从penangiana Abacopteris根茎中分离到两个新的乙酰化黄酮苷(2S,4R)-4,5,7-三羟基-4′-甲氧基-6,8-二甲基黄酮-5- o -β- d -6-乙酰-d -葡萄糖苷(1)和(2S,4R)-5,7-二羟基-4,4′-二甲氧基-6,8-二甲基黄酮-5- o -β- d -6-乙酰-葡萄糖苷-7- o -β- d -葡萄糖苷(2)。利用IR、HR-ESI-MS、1D和2D NMR等光谱方法和化学证据对其结构进行了鉴定。
Two new acetylated flavan glycosides (2S,4R)-4,5,7-trihydroxy-4′-methoxy-6,8-dimethylflavan-5-O-β-D-6-acetylglucopyranoside-7-O-β-D-glucopyranoside (1) and (2S,4R)-5,7-dihydroxy-4,4′-dimethoxy-6,8-dimethylflavan-5-O-β-D-6-acetylglucopyranoside-7-O-β-D-glucopyranoside (2) were isolated from the rhizomes of Abacopteris penangiana. Their structures were elucidated on the basis of spectroscopic methods including IR, HR-ESI-MS, 1D and 2D NMR, and chemical evidences.
