A new isoflavone from soya beans

A new isoflavone was isolated from soya beans and shown to be 7,4′-dihydroxy, 6-methoxyisoflavone, for which the name glycitein is proposed.     

Isoflavonoids from Cyclolobium species

(3R)-Claussequinone (7-hydroxy-4′-methoxyisoflavanquinone is the principal constituent of Cyclolobium clausseni Benth. and C. vecchii A.     

A new species of Lathyrus L. (section Cicercula; Fabaceae) from Turkey

A new species, Lathyrus egirdiricus H.Genc & A.Sahin (section Cicercula; Fabaceae), is described from Turkey, with illustrations and taxonomic comments. Characteristics of the species are compared with those of the related species Lathyrus hirsutus L., L. stenophyllus Boiss. & Heldr., L. sativus L., L. cassius Boiss. and L. gorgoni Parl., from which it differs mainly in the shape, length, width and venation of leaflets, length and width of the stipule, flower colour, legume and style length. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 158 , 301–305.     

New isoflavonoids related to kievitone from Phaseolus vulgaris

The new isoflavonoids 5,7,2′,4′-tetrahydroxy-8-(3,3-dimethylallyl)isoflavone (2,3-dehydrokievitone) and 7,2′,4′-trihydroxy-8-(3,3-dimethylallyl)isoflavanone (5-deoxykievitone) have been isolated from fungus-inoculated Phaseolus vulgaris pod tissue and from the inoculation droplets. A third isoflavonoid was tentatively identified as 1″,2″-dehydrocyclokievitone and appears to be a metabolite of the phytoalexin kievitone.     

Isolation of a new isoflavan phytoalexin from two Lotus species

A phytoalexin isolated from the fungus-inoculated leaflets of Lotus angustissimus and L. edulis has been characterised as 5,7-dimethoxy-2′,4′-dihydroxyisoflavan (lotisoflavan). The total synthesis of lotisoflavan is described.     

A new species of Hedysarum (Fabaceae) in Iran and other new Hedysarum records

Hedysarum al-shehbazii , a new species endemic to Iran, is described and illustrated. This species belongs to Hedysarum section Multicaulia . It is confined to the western part of Iran (Kermanshah Province), and is known from a single population close to the Iraq frontier, although possibly also growing in the adjoining eastern part of Iraq. The conservation status of this species is 'vulnerable' according to World Conservation Union (IUCN) criteria. In addition, H. varium and H. syricum are reported as new records from a single gathering close to the Turkish frontier. Moreover, H. kotschyi and H. pogonocarpum are transferred from Hedysarum section Crinifera to Hedysarum section Multicaulia .  © 2007 The Linnean Society of London, Botanical Journal of the Linnean Society , 2007, 155 , 505–512.     

Further studies on the isoflavones of Tephrosia maxima

A new 7,8-methylenedioxyisoflavone, maxima isoflavone H, was isolated from Tephrosia maxima along with the known isoflavone, maxima isoflavone B.     

A new species of Astragalus L. (section Onobrychoidei DC.: Fabaceae) from Turkey

A new species of Astragalus L., A. trabzonicus (section Onobrychoidei DC.), is described and illustrated from north‐east Anatolia in Turkey. The diagnostic, pollen morphological, and chromosomal characteristics are discussed. A distribution map and conservation status are given. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 157 , 741–747.     

Alkaloid distribution in some new world Lupinus species

Alkaloidal profiles of 21 Lupinus species indigenous to North and South America have been determined. Nineteen quinolizidine alkaloids were identified, including aphyllidine and N-methylcytisine, which have not previously been found in the genus. Two dipiperidine alkaloids were also detected. The pattern of alkaloidal distribution is related to a taxonomic classification of the genus.
