Eimeria melogale n. sp. (Apicomplexa: Eimeriidae) in the Javan ferret-badger (Melogale orientalis)

The Javan ferret-badger Melogale orientalis (Carnivora: Mustelidae: Helictidinae) is a small carnivore endemic to Indonesia. In the family Mustelidae, 10 Eimeria, 12 Cystoisopora, one Isospora, and one Hammondia species are known, but no eimeriid coccidia has been yet described in the subfamily Helictinidae (ferret badgers). Coproscopic examination of Javan ferret-badgers imported into the Czech Republic revealed the presence of coccidian oocysts. Sporulated oocysts differ from other Eimeria known in the family Mustelidae by their small size (12.4–16.1 × 10.4–13.4 μm) and ovoidal shape. Morphological data and phylogenetic analyses of 18S rRNA and COI genes indicated a new species of Eimeria found in faecal samples of Javan ferret badgers. The species is described as E. melogale n. sp.     

Chemical study of the seeds of Erythrophleum ivorense A. Chev. (Fabaceae)

The Chemical study of methanolic extract of the seeds from Erythrophleum ivorense led to the isolation of one original cassane diterpenoid (1) along with six known cassane diterpenoids (2–7). In addition, the known compounds (2–7) are isolated for the first time in E. ivorense. Their structures were established according to their spectral data (NMR, HRESIMS, IR). This result confirms that cassane-type diterpenoids are one of the major constituents of Erythrophleum species. The identification of these compounds and their chemotaxonomic significance is discussed.     

Ossicaulis yunnanensis sp. nov. (Lyophyllaceae,Agaricales) from southwestern China

Ossicaulis is a small genus in the family Lyophyllaceae. Two known species, O. lachnopus, and O. lignatilis, are distributed in north temperate regions. The third taxon, O. yunnanensis sp. nov., is described from the alpine belt of subtropics of southwestern China, and this genus is also reported for the first time from China. Morphologically, the new species is characterized by its whitish basidiomata and very small basidiospores. Molecular analyses from the nuclear rDNA internal transcribed spacer region (ITS) show that the subtropical alpine species is distinct from hitherto known Ossicaulis species and has a close relationship to O. lachnopus.     

New Paramecium quadecaurelia strains (P. aurelia spp. complex,Ciliophora) identified by molecular markers (rDNA and mtDNA)

Paramecium quadecaurelia is a rare species (previously known only from two locations) belonging to the P. aurelia species complex. In the present paper, fragments of an rDNA gene (ITS1-5.8S-ITS2-5′ rDNA) and mtDNA genes (cytochrome oxidase subunit I and cytochrome b regions) were employed to assist in the identification and characterization of three new strains collected from Ecuador and Thailand. Molecular data were confirmed by mating reactions. In rDNA and mtDNA trees constructed for species of the P. aurelia complex, all P. quadecaurelia strains, including the three new strains discussed in this study and two known previously from Australia and Africa, form a monophyletic but differentiated clade. The present study shows that genetic differentiation among the strains of P. quadecaurelia is equal to or even greater than the distances between some other P. aurelia species, e.g., P. primaurelia and P. pentaurelia. Such great intra-specific differentiation may indicate a future splitting of the P. quadecaurelia species into reproductively isolated lines.     

Dammarane triterpenes from Cabralea canjerana (Vell.) Mart. (Meliaceae): Their chemosystematic significance

The stem of Cabralea canjerana (Vell.) Mart. yielded three new dammarane triterpenes 20S,24S-epoxy-7β,25-dihydroxy-3,4-secodammar-4(28)-en-3-oic acid, 20S,24S-epoxy-7β,15α,25-trihydroxy-3,4-secodammar-4(28)-en-3-oic acid and 20S,24R-epoxy-7β,22ξ,25-trihydroxy-3,4-secodammar-4(28)-en-3-oic acid, which were identified on the basis of spectroscopic methods. The known dammarane triterpenes ocotillone, eichlerianic acid, shoreic acid and the sterols sitosterol, campesterol, stigmasterol, sitostenone and stigmast-5-en-3-one were also isolated and identified. The branches yielded the above three known dammaranes and eichlerialactone. The dammaranes in C. canjerana display strong similarities with Trichilieae tribe, which contains several dammaranes. The data reported herein thus provide firm support for placing Cabralea within the subfamily Melioideae, Trichilieae tribe.     

Cytotoxic sesquiterpenoids from Dysoxylum parasiticum (Osbeck) Kosterm. stem bark

Two undescribed sesquiterpenoid derivatives, 10β,11-dihydroxy-1β-hydroperoxide-4αH,5αH,7βH-guaiane (1) and 10β-hydroxy-4α,4β-dimethyl-5αH,7αH-eudesm-3-one (2) along with three known of guaiane, aromadendrane, and cadinane sesquiterpenoids (3-5) were isolated from the stem bark of Dysoxylum parasiticum (Osbeck) Kosterm. The chemical structure of the compounds were determined by detailed analysis of spectroscopic data, including MS, IR, 1D, and 2D NMR as well as through comparison with data of known analogues. The isolated compounds were also tested for cytotoxic properties against MCF-7 breast cancer line. Compound 4, was found to exhibit the strongest cytotoxic activity with an IC₅₀ value of 12.17 μM, while the other compounds showed moderate or no activity.     

New unsaturated fatty acid and other chemical constituents from the roots of Cola rostrata K. Schum. (Malvaceae)

Phytochemical investigation of the roots of Cola rostrata K. Schum. led to the isolation of a new unsaturated fatty acid, named rostratanic acid (1), together with fourteen known compounds, lignoceric acid, friedelan (7), friedelanone (8), bauerenol (3), lupeol (4), herranone (9), acotatarone A (11), betulinic acid (6), betulin (5), nonanedioc acid (2), arjunolic acid (10) stigmasterol, β−sitosterol, and β−sitosterol-3-O-β-D-glucopyranoside. The structure of the new compound as well as those of the known compounds were established by means of spectroscopic methods: NMR analysis (¹H and ¹³C NMR, ¹H–¹H–COSY, HSQC and HMBC) and high-resolution mass spectrometry (HR-ESI-MS), and by comparison with previously reported data. Two of those known compounds were modified chemically to afford three new derivatives. All those compounds were tested for their cytotoxic activity against the human cervix carcinoma KB-3-1 cells and their antibacterial activity against Escherichia coli, Salmonella enterica, Pseudomonas aeruginosa and Staphylococcus aureus. Although the crude extract gave weak antibacterial activity, none of the isolated compounds showed antibacterial activity, and, only the prenylated derivative showed weak cytotoxicity. In addition, the chemotaxonomic significance of the species Cola rostrata is discussed.     

A new sesquiterpenoid from Sclerorhachis platyrachis (Boiss.) Podlech ex Rech.f

A new eudesmane-type sesquiterpenoid together with two known flavonoids were isolated from the chloroform extract of the aerial part of Sclerorhachis platyrachis. The structure of the new compound was deduced from its comprehensive spectroscopic analysis including IR, EI-MS, ¹H NMR, ¹³C NMR, DEPT, COSY, HMBC and HMQC and was shown to be 4R^*-hydroxy-6S^*-tigloyloxyeudesma-7S^*-11 (13)-en-12-oic acid (1). Finally, the structure of the new compound was unambiguously confirmed by single-crystal X-ray analysis. The structure of known compounds 2 and 3 were identified by comparison of their spectral data with those reported in the literature.     

Flavonoids from the Turkish endemic plant Rhaponticoides mykalea (Hub.-Mor.) M.V.Agab. & Greuter (Asteraceae)

The genus Rhaponticoides, recently segregated from the genus Centaurea, belongs to the family Asteraceae (tribe Cardueae). Rhaponticoides mykalea (Hub.-Mor.) M.V.Agab. & Greuter is an endemic species narrowly distributed in the Aegean part of Turkey. Owing to the existing anthropogenic impacts (such as urbanization and road construction) throughout its distribution range, the species has been the subject of several conservation studies. Phytochemical research on the aerial parts of R. mykalea led to the isolation of a new flavonoid, namely patuletin 7-O-(6″-E-sinapyl)-β-glucopyranoside, together with four known flavonoids from n-butanol extract. The structures of all isolated compounds were elucidated by spectroscopic analysis (1D and 2D NMR, HR-ESI-MS), as well as by comparison with the relevant literature data. All of the compounds have been isolated from the genus Rhaponticoides for the first time.     

A new putrescine bisamide phenolic glycoside from the seeds of Lallemantia iberica (M. Bieb.) Fisch. & C. A. Mey

Bieb.) Fisch. & C. A. Mey. Their structures were elucidated by spectroscopic analysis, and by comparison with literature data. This is the first report of phenolic glycosides from genus Lallemantia.     

Acylated cyanidin 3-sambubioside-5-glucosides from the purple-violet flowers of Matthiola longipetala subsp. bicornis (Sm) P. W. Ball. (Brassicaceae)

A novel acylated cyanidin 3-sambubioside-5-glucoside was isolated from the purple-violet flowers of Matthiola longipetala subsp. bicornis (Sm) P. W. Ball. (family: Brassicaceae), and determined to be cyanidin 3-O-[2-O-(2-O-(trans-feruloyl)-β-xylopyranosyl)-6-O-(trans-feruloyl)-β-glucopyranoside]-5-O-[6-O-(malonyl)-β-glucopyranoside] by chemical and spectroscopic methods. In addition, two known acylated cyanidin 3-sambubioside-5-glucosides, cyanidin 3-O-[2-O-(2-O-(trans-sinapoyl)-β-xylopyranosyl)-6-O-(trans-feruloyl)-β-glucopyranoside]-5-O-[6-O-(malonyl)-β-glucopyranoside] and cyanidin 3-O-[2-O-(β-xylopyranosyl)-6-O-(trans-feruloyl)-β-glucopyranoside]-5-O-[6-O-(malonyl)-β-glucopyranoside] were identified in the flowers.     

Molecular phylogeny and new taxa in the Archaeosporales (Glomeromycota): Ambispora fennica gen. sp. nov., Ambisporaceae fam. nov., and emendation of Archaeospora and Archaeosporaceae

The AM fungal family Archaeosporaceae and the genus Archaeospora are rendered paraphyletic by the relationship with the Geosiphonaceae. This problem led to a more detailed study of the Archaeosporales. Members of the Archaeosporaceae were described as forming both glomoid and acaulosporoid spores, or solely acaulosporoid spores. However, we found that Glomus callosum fell into the same phylogenetic clade as A. leptoticha and A. gerdemannii, but exclusively formed glomoid spores. To resolve these inconsistencies, a genus, Ambispora gen. nov., typified by Ambispora fennica sp. nov., is erected based on morphological evidence and SSU and ITS region rDNA data. Ambispora contains three species known to produce both acaulosporoid and glomoid spores: A. fennica, A. leptoticha comb. nov. (basionym G. leptotichum), and A. gerdemannii comb. nov. (basionym G. gerdemannii). Another species, A. callosa comb. nov. (basionym G. callosum), is known only from glomoid spores. Ambispora is placed in a new family, the Ambisporaceae fam. nov. The Archaeosporaceae is maintained with the type species, Archaeospora trappei (basionym Acaulospora trappei), along with Intraspora schenckii (basionym Entrophospora schenckii). Acaulospora nicolsonii, known only from acaulosporoid spores, is discussed and is considered likely to belong in the Ambisporaceae, but is retained within its present genus because of inadequate morphological information and a lack of molecular data.     

Alilepus meini nov. sp. (Leporidae,Lagomorpha) from the Early Messinian of Tuscany (central-western Italy)

Alilepus meini nov. sp., a new leporid known only from the Early Messinian of central-western Italy (Baccinello-Cinigiano basin, V3 faunal assemblage; Tuscany), is described here. A. meini nov. sp. is an endemic taxon – not inherited from the older Tusco-Sardinian assemblages – of the continental and balanced BCB V3 fauna. The peculiarities of A. meini nov. sp. mainly reside in the occlusal surface of p3 (very large anteroconid, extremely short talonid, deep and crenulated posterior flexids, extremely thin protoisthmus) and P3 (wide hypoflexus). A. meini nov. sp. seems closely related to Alilepus turolensis, as testified by shared morphological characters (globous anteroconid and deep protoflexid, very thin protoisthmus). Palaeobiogeographical evidences support morphological data as A. meini nov. sp. and A. turolensis are the only two species of the genus present in western Europe.     

Chemical constituents from Alnus mandshurica (Callier) Hand.-Mazz. and their chemotaxonomic significance

A new phenol compound, (9S)-9-hydroxy-9-[(2-hydroxyphenyl)methoxy]-nonanoic acid methyl ester (1) was isolated from the stem bark of Alnus mandshurica (Callier) Hand.-Mazz., along with eight known compounds (2–9). The structure of compound 1 was determined by spectral analyses, including HR-ESI-MS, 1D and 2D NMR (COSY, HMQC and HMBC) experiments. All the isolated compounds were reported for first time from A. mandshurica. Furthermore, compounds 3–9 were found in the family Betulaceae for the first time.     

Saponins from Astragalus hareftae (NAB.) SIRJ.

Four cycloartane- (hareftosides A–D) and oleanane-type triterpenoids (hareftoside E) were isolated from Astragalus hareftae along with fifteen known compounds. Structures of the compounds were established as 3,6-di-O-β-d-xylopyranosyl-3β,6α,16β,24(S),25-pentahydroxycycloartane (1), 3,6,24-tri-O-β-d-xylopyranosyl-3β,6α,16β,24(S),25-pentahydroxycycloartane (2), 3-O-β-d-xylopyranosyl-3β,6α,16β,25-tetrahydroxy-20(R),25(S)-epoxycycloartane (3), 16-O-β-d-glucopyranosyl-3β,6α,16β,25-tetrahydroxy-20(R),24(S)-epoxycycloartane (4), 3-O-[β-d-xylopyranosyl-(1→2)-O-β-d-glucopyranosyl-(1→2)-O-β-d-glucuronopyranosyl]-soyasapogenol B (5) by the extensive use of 1D- and 2D-NMR experiments along with ESI-MS and HR-MS analyses.
