目的研究黑老虎Kadsuracoccinea根95%乙醇提取物的化学成分。方法利用多种色谱方法进行分离,根据理化性质和波谱学手段对分离得到的化合物进行结构鉴定。结果分离得到12个化合物,分别鉴定为24ξ-n-丙基-胆甾-3-酮(24ξ-n-propyl-cholestan-3-one,1)、豆甾-5-烯-7-羰基-3β-醇(stigmast-5-en-7-oxo-3β-ol,2)、豆甾-5-烯-3β,7α-二醇(stigmast-5-en-3β,7α-diol,3)、clovane-2β,9α-diol(4)、美国茶叶花素(草夹竹桃苷,androsin,5)、正丁基-β-D-吡喃果糖苷(n-butyl-β-D-fructopyranoside,6)、香草酸(vanillic acid,7)、香草醛(vanillin,8)、原儿茶酸(protocatechuic acid,9)、莽草酸(shiki mic acid,10)、β-谷甾醇(β-sitosterol,11)和胡萝卜苷(daucosterol,12)。结论化合物1~6为首次从该属植物中分离得到。
Aim To study the chemical composition of 95% ethanol extract of black tiger Kadsuracoccinea root. Methods A variety of chromatographic methods were used for the separation. The structures of the isolated compounds were identified by their physico-chemical properties and spectroscopic methods. Results Twelve compounds were isolated and identified as 24ξ-n-propyl-cholestan-3-one (1) Stigmast-5-en-7-oxo-3β-ol, stigmast-5-en-3β, 7α-diol, Clovane-2β, 9α-diol (4), American tea flower anthocyanin (androsin, 5), n-butyl-β-D-fructopyranoside 6, vanillic acid (7), vanillin (8), protocatechuic acid (9), shiki mic acid (10), β-sitosterol 11) and daucosterol (12). Conclusion Compounds 1 ~ 6 were isolated from this genus for the first time.
