摘 要:采用硅胶、Sephadex LH-20、高效制备液相等方法,对红药根的甲醇提取物进行分离纯化,通过质谱(MS)、波谱数据分析(^1H,^13C-NMR)进行结构鉴定。从红药根的甲醇提取物中分离7个化合物,分别鉴定为plantainoside A(1),plantainoside B(2),calcedarioside C(3),calcedarioside D(4),platyphylloside(5),hirsutanonol(6)和hirsutanonol-5-O-β-D-glucopyranoside(7)。化合物均5-7为首次从该科物中分离得到。To study the chemical constituents from the roots of Chirita longgangensis var. hongyao. The methanol extract was isolated and purified by silica gel,Sephadex LH-20 and preparative HPLC. Their structures were elucidated by MS and spectral data(^1H,^13C-NMR). Seven compounds were isolated and identified as plantainoside A(1),plantainoside B(2),calcedarioside C(3),calcedarioside D(4), platyphylloside(5),hirsutanonol(6), and hirsutanonol-5-O-β-D-glucopyranoside(7). Compounds 5-7 were isolated for the first time from the family Gesneriaceae.
