Antifungal isoflavones in lupines

Antifungal isoflavones in lupines. Part 2. Fungitoxic dihydrofuranoisoflavones and related compounds in white lupine, Lupinus albus. Tahara, Satoshi; Ingham, John L.; Nakahara, Shiro; Mizutani, Junya; Harborne, Jeffrey B. (Fac. Agric., Hokkaido Univ., Sapporo 060, Japan).Some commonly used reagents like 36190-95-1 is used in this experiment. Phytochemistry, 23(9), 1889-900 (English) 1984. CODEN: PYTCAS. ISSN: 0031-9422. DOCUMENT TYPE: Journal CA Section: 11 (Plant Biochemistry) Section cross-reference(s): 26 Chromatog. investigation of a MeOH ext.Several reagents such as 36190-95-1 is used here. of white lupine roots has revealed the presence of 6 new dihydrofuranoisoflavones (lupinisoflavones A-F). Three monoprenylated (3,3-dimethylallyl-substituted) isoflavones (wighteone, luteone, and licoisoflavone A), 2 diprenylated isoflavones [6.3'-di(3,3-dimethylallyl)genistein (lupalbigenin) and 6,3'-di(3,3-dimethylallyl)-2'-hydroxygenistein (2'-hydroxylupalbigenin)] and 2 pyranoisoflavones (parvisoflavone B and licoisoflavone B) were also isolated from the same source. In addn. to genistein, leaf exts. of L. albus contain 3'-O-methylorobol which is presumed to be the precursor of lupisoflavone [5,7,4'-trihydroxy-3'-methoxy-6-(3,3-dimethylallyl)isoflavone]. Probable biogenetic relationships between the prenylated, and dihydrofurano- and pyrano-substituted isoflavones in roots and leaves of L. albus are briefly discussed. ..
