isolated from the seeds of Tephrosia apollinea and identified as the diastereoisomers (−)-semiglabrin and (−)-pseudosemiglabrin, (+)-glabratephrin, (+)-glabratephrinol, appollinine (7-methoxy-8-[3″-(2″,5″-dihydro-5″,5″-dimethyl-2″-oxofuryl)]-flavone and lanceolatin-A. The use of 13C NMR in the structure elucidation of flavones of this type is discussed. The potential chemotaxonomic value of Tephrosia flavones
摘要 共分离出 6 种复杂的 7-氧化 8-异戊二烯黄酮,分别为非对映异构体 (-)-semiglabrin 和 (-)-pseudosemiglabrin、(+)-glabratephrin、(+)-glabratephrinol , appollinine (7-methoxy-8-[3″-(2″,5″-dihydro-5″,5″-dimethyl-2″-oxofuryl)]-flavone and lanceolatin-A。13C NMR在讨论了该类型黄酮的结构解析,并探讨了从 T. apollinea 中分离的该类型的 Tephrosia 黄酮的潜在化学分类学价值。
