摘要：

A new di-C-glucosylflavone, 2 '',2'''-di-O-beta-glucopyranosyl-vicenin II and a new flavonol di-O-glycoside, herbacetin 3-O-alpha-rhamnopyranoside-8-O-beta-glucopyranoside, were isolated from the aerial parts of Ephedra aphylla. Vicenin II, the 7-methoxy-4-quinolone 2-carboxylic acid, ephedralone, p-hydroxybenzoic, p-coumaric, protocatechuic acids and herbacetin 7-methyl ether were also isolated. The C-13 NMR spectrum of the latter compound has been assigned for the first time. (C) 1997 Elsevier Science Ltd. All rights reserved.
