虎尾草化学成分研究

Chemical Constituents of Lysimachia barystachys

从虎尾草Lysimachia barystachys地上部分中分得8个已知黄酮苷类化合物,通过波谱解析其结构分别鉴定为槲皮素(1),山奈酚(2),金丝桃苷(3)、芦丁(4)、3,5,7,3′,4′-五羟基黄酮-3-O-(2,6-二-O-α-L-吡喃鼠李糖)-β-D-吡喃半乳糖苷(5),3,5,7,3′,4′-五羟基黄酮-7-O-α-L-吡喃鼠李糖-3-O-α-L-吡喃鼠李糖(1-2)-β-D-吡喃葡萄糖苷(6),3,5,7,4′-四羟基黄酮-3-O-(2,6-二-O-α-L-吡喃鼠李糖)-β-D-吡喃半乳糖苷(7),3,5,7,4′-四羟基黄酮-7-O-α-L-吡喃鼠李糖-3-O-α-L-吡喃鼠李糖(1-2)-β-D-吡喃葡萄糖苷(8)。这些化合物除3,4外均为首次从该植物中分离得到。

From the aerial parts of the plants of Lysimachia barystachys, eight known compounds were isolated. Their structures were elucidated as following based on spectral methods ： quereetin （ 1 ）, kaempferol （ 2 ）, hyperin （ 3 ）, rutin （4） , quercetin-3 -0 - （ 2,6-di-O -α-L-rhamnopyranosyl-β-D-galactopyranoside） （ 5 ） , quereefin-7 -O-α-L-rhamnopyranoside-3-O- α-L-rhamnopyranosyl（ 1-2）- β-D-glueopyranoside （6）, kaempferol-3-O -（2,6-di-O-a- L-rhamnopyranosyl-β-D-galaeto- pyranoside） （ 7 ） , kaempfeml-7-O-α-L-rhamnopyranosyl-3-O-α-L-rhamnopyranosyl （ 1-2 ） - β-D-glucopyranoside （ 8 ）. All compounds were isolated for the first time from this plant except hyperin and turin.
