Abstract
Five acylated 5,7,2',6'-oxygenated flavone glycosides along with the known 5,2',6'-trihydroxy-7-methoxyflavone-2'-O-beta-d-glucopyranoside have been isolated from the whole plant of Andrographis alata. The structures of the compounds were established from spectral (mainly 1D and 2D NMR) and chemical studies.
摘要
从翅柄穿心莲全株中分离出5种酰化的5,7,2',6'-氧化黄酮苷以及已知的5,2',6'-三羟基-7-甲氧基黄酮-2'-O-β-D-吡喃葡萄糖苷。通过光谱（主要是一维和二维核磁共振）和化学研究确定了这些化合物的结构。
