In an attempt to find species specific markers, a phenoxychromone () and eight isoflavonoids including six isoflavans () and two isoflavanones ( and ) were isolated from the root of . Among the isolated phenolic compounds, glycyurelone (), glycyurelvanins A and B ( and ) were found to be undescribed while others, (-)-vestitol (), conferol A (), glyasperin C (), glyasperin D (), (-)-licoisoflavanone (), and (-)-3'-(γ,γ-dimethylallyl)kievitone () were previously reported. All compounds except and were prenylated and majority of these possess isoflavan scaffold with highly conserved stereo specificity at C-3 center. Structure elucidation was mainly based on extensive NMR, ECD and mass spectral data analysis.
为了寻找具有物种特异性的标记物,从 的根部分离得到苯并色酮()和八种异黄酮,包括六种异黄烷()和两种异黄酮酮(和)。在所分离的酚类化合物中,发现glycyurelone()、glycyurelvanins A 和 B(和)是未描述的,而其他化合物,(-)-vestitol()、conferol A()、glyasperin C()、glyasperin D()、(-)-licoisoflavanone()和(-)-3'-(γ,γ-二甲基烯丙基)kievitone()以前曾有报道。除了和之外,所有化合物都被 prenylated,其中大多数具有异黄烷骨架,并在 C-3 中心具有高度保守的立体特异性。结构阐明主要基于广泛的 NMR、ECD 和质谱数据分析。
