藿香枝叶多糖的提取工艺及其清除羟基自由基作用研究

采用苯酚-硫酸,并以超声法辅助提取野生藿香枝叶中的多糖,设计L9(34)正交试验考察料液比、pH和超声提取时间对藿香枝叶中多糖提取的影响,并对藿香多糖进行清除.OH试验。结果表明,藿香多糖的最佳提取工艺为料液比1∶10,超声提取30min,pH值为6,可使藿香多糖的提取率高达7.50%。藿香多糖对羟基自由基有显著地清除效果,表明其有抗氧化作用。     

Ultrastructure of Ascodichaena rugosa on beech bark

Ascodichaena rugosa Butin is a corkinhabiting fungus, found frequently on the bark of Fagus sylvatica L. The hyphae of the fungus are distributed solely in the phellem cells, stopping their growth in the last-formed cork cell layer. The cell to cell invasion is effected by penetration hyphae, causing no extensive dissolution of the cork wall. Electron microscopical observations revealed fine structural details of the fruit bodies and of the intracellular hyphae. Of special interest were the finger-like hyaline hyphae in the last-formed layer of cork cells, which are interpreted as haustoria on the basis of the fine structure both of hyphae and host cells. This situation is considered as reflecting a parasitic relationship of Ascodichaena to beech bark. The activity of the fungus led also to the increased production of cork cells, perhaps related to the nutrient supply of the fungus.     

(+)-4-epi-alpha-bisabolol as a major sesquiterepene constituent in the leaves of two Rosa rugosa hybrids, Martin Frobisher and Vanguard

During an investigation of the sesquiterpene phases and contents in leaves of several Rosa rugosa hybrids (hybrid rugosas), Martin Frobisher and Vanguard were found to accumulate a large amount of (+)-4-epi-alphabisabolol (1) as a single constituent. Although glandular trichomes of Martin Frobisher on the leaves are dense, this R. rugosa hybrid produces none of the carota-1,4dienaldehyde (2) or bisaborosaol A (3) that are both found as representative sesquiterpenes of the carotane and bisabolane classes, respectively, in a glandular trichome exudate of wild-type R. rugosa. Compound 1 was also apparent as a nearly single constituent detectable by GC in the leaf constituents of Vanguard possesses sparse glandular trichomes on the leaf. Martin Frobisher and Vanguard had likely lost their capability to form carotane-type sesquiterpenes and had also lost their activity to oxygenate the C-7 allyl methyl carbon of compound 1 to convert 3. The presence of (+)-4-epi-alphabisabolol-accumulating R. rugosa hybrids is significant when considering the sesquiterpene biogenesis of Rosa rugosa.     

Effects of Rosa rugosa petals on intestinal bacteria

The effects of pulverized petal of Rosa rugosa on the growth of 10 species of intestinal and pathogenic bacteria were investigated. Growth of bifidobacteria and lactobacilli was not affected by the addition of the petal in plate cultivation. However, the growth of Bacteroides vulgatus, Escherichia coli, Staphylococcus aureus, and Bacillus cereus was completely inhibited by the addition of 0.1, 0.5, 0.1, and 0.05% (w/v) of the petal respectively. In liquid cultivation, the addition of the petal (0.5%) stimulated the growth of Bifidobacterium breve and slightly inhibited the growth of Lactobacillus salivarius. But the growth of E. coli, S. aureus, B. cereus, and Salmonella sp. was inhibited by nearly 50%. Hydrolyzable tannins isolated from R. rugosa, rugosin D, and tellimagradin II showed antibacterial activities against E. coli, S. aureus, B. cereus, and Salmonella sp., but little or no effect against Bif. breve and L. salivarius. R. rugosa petal showed selective antibacterial activities against intestinal and pathogenic bacteria, and the selectivity resembled that of prebiotics such as oligosaccharides and dietary fiber. Hydrolyzable tannins in R. rugosa, such as rugosin D and tellimagradin II, must be active constituents.

First report of Litomosa spp. (Nematoda: Filarioidea) from Malagasy bats; review of the genus and relationships between species

The presence of the filarial genus Litomosa in Malagasy bats is demonstrated by the finding of L. goodmani n. sp. from Miniopterus gleni and Litomosa sp. (male unknown) from M. manavi, both in the Special Reserve of Ankarana. These materials are compared to the 22 Litomosa species, including two Indian species originally placed in the genus Litomosoides, L. fotedari (Gupta and Trivedi, 1989) n. comb. and L. tewarii (Gupta and Trivedi, 1989) n. comb., and the new taxon L. seurati n. sp. (= L. beaucournui Bain, 1966 pro parte), type-host Rhinolophus ferrum-equinum, Algeria, distinguished by the narrow area rugosa and the female caudal extremity with two conspicuous points, instead of several small ones. The Malagasy material belongs to a group of species close to the type, L. filaria, which have a male area rugosa composed of cuticular bosses and microfilariae folded within the sheath, and which are parasitic in Vespertilionidae, Hipposideridae and Rhinolophidae from Africa and Europe. The two Malagasy species resemble L. seurati n. sp., L. beshkovi Jancev, 1971, L. chiropterum Ortlepp, 1932, L. adami Petit, 1980 and L. ottavianii Lagrange et Bettini, 1948, with the enlarged third segment of the buccal capsule. L. goodmani n. sp. is distinct with its small size and female caudal extremity with a single point, which is suppressed in old mature worms; the females of Litomosa sp. have two conical points. Relationships among Litomosa species appear to be dependent upon both the chiropteran host groups and the geographical region.     

Inhibition of lipase activity by low-molecular-weight chitosan

Inhibition of enzymatic activity of lipase (EC 3.1.1.3) from the fungus Candida rugosa and wheat (Triticum aestivum L.) germ by low-molecular-weight chitosan with an average molecular weight of 5.7 kDa in reactions of p-nitrophenyl palmitate cleavage was studied. Preincubation of lipases with chitosan, prior to addition of the substrate to solution, showed that equilibrium during the lipase-inhibitor complex formation was reached within 30 min. The inhibition constants for C. rugosa lipase and wheat germ lipase were 1.4 and 0.9 mM, respectively. The contribution of electrostatic interactions to the complex formation between chitosan and lipases is insignificant.
