宽叶金粟兰中1个新的倍半萜

A new sesquiterpene from Chloranthus henryi

运用硅胶柱色谱、ODS柱色谱、Sephadex LH-20柱色谱和制备型高效液相等方法从宽叶金粟兰Chloranthus henryi乙醇提取物中分离提取得到8个倍半萜类化合物,并根据波谱数据和理化性质对其进行结构鉴定,分别鉴定为:(1S,6S,8S,10R)-8-ethoxy-10-methoxychlomultin C (1),tianmushanol (2),multistalide A (3),myrrhterpenoid N (4),1α,9α-二羟基-8,12-环氧桉叶-4,7,11-三烯-6-酮(5),4β,10α-香木兰烷二醇(6),oplopanone (7),10α-hydroxycadinan-4-en-3-one (8)。其中化合物1为新化合物,化合物2~8首次从宽叶金粟兰中分离得到。

Eight sesquiterpenes were isolated and purified from the ethanol extract of Chloranthus henryi by column chromatographies over silica gel, ODS and Sephadex LH-20,and preparative HPLC. Their chemical structures were established by spectral data and physiochemical properties as(1S,6S,8S,10R)-8-ethoxy-10-methoxychlomultin C(1),tianmushanol(2),multistalide A(3),myrrhterpenoid N(4),1α,9α-dihydroxy-8,12-expoxy-eudesma-4,7,11-trien-6-one(5),4β,10α-aromadendranediol(6),oplopanone(7),10α-hydroxycadinan-4-en-3-one(8). Among them, compound(1) was a new compound, and compounds 2-8 were isolated from Chloranthus henryi for the first time.
