摘要：

用HPLC法研究了具8位异戊烯基的黄酮醇甙类(A类)及一般结构的黄酮醇甙类(B类)在淫羊

藿属Epimedium L.中的存在和含量情况，得到一些具分类学意义的结论。1)依据化学成分可将

Epimedium 分为3群：A群，主要含A类成分；B群，主要含B类成分；AB群，两类化合物含量都高。B

群的8个类群(种或亚种)有多项演化程度较高的形态特征，它可能是Epimedium发展演化中较为进化

的一个分支群。—朋群的种类为本屑较原始的类群，因而在化学性状上有朋群→A群、AB群→B群的

演化趋势，与形态演化趋势基本相关。A、B、AB群的划分与现有分类系统不一致，也与花粉、染色体C

带的结果不很吻合。2)分布于地中海的E. alpinum因有较高含量的厶2类成分(A类中4'-OH的一类

化合物)而体现了与中国的原始类群的一些联系。3)E. davidii和E. ecalcaratum的化学成分几乎相

同，表明花瓣距的有无在Epimedium中的原始类群可能不具重要的分类价值。4)HPLC图谱为E.Х

fanjingshanense这一杂交种的亲本来源提供了可靠的证据。本研究结果为建立一个合理的Epimedium

的分类系统提供了新的依据。

Abstract:

In this paper, the distribution and quantity of flavonol glycosides with isoprenyl in

the eighth position (A kind) or without isoprenyl (B kind) in Epimedium were analyzed by

HPLC. The following results of taxonomic significance were obtained: 1 )According to the

chemical characteristics, Epimedium could be divided into three groups: A group, mainly

with A kind of flavonol glycosides; B group, mainly with B kind of fiavonol glycosides; AB

group, sharing the two kinds. Eight taxa (species or subspecies) in B group, which have

many advanced charaetaristics, should represent a more advanced group of the genus. The

species of AB group were relatively primitive in the genus. Hence the evolutionury trend

from AB group to A group and then to B group was possible. This trend is basically correlat-

ed with that of morphological evolution. But the above groupings of A, B and AB do not ac-

cord with Stearn's taxonomic system and the results of pollen morphology and of chromo-

some C-bands. 2)E. alpinum, a species distributed in the Mediterranean area, contains a

high quantity of A2 kind of compounds (those of A kind with 4'-OH), so it may be some-

what related to the primitive species in China. 3)The constituents of E. davidii and E. e-

calcaratnm are almost identical, implying that the prescence or absence of the spur of the

petal should be of unimportant systematic significance. 4)The chromngram of HPLC provid-

ed reliable evidence for determining the parental origin of the hybrid E. x fanjingshanense.

The results of this work provided new evidence for establishing a more reasonable taxonomic

system of Epimediurn, but the taxonomic research on Epimedium has a long way to go and

more work must be done. Other chemical characteristics of Epimedium and its relationship

with other groups in the Berberidaceae were also discussed.
