目的 研究深裂銹毛莓氯仿部位的化學(xué)成分。方法 采用硅膠柱色譜和重結(jié)晶方法進(jìn)行分離純化，根據(jù)化合物的理化性質(zhì)和波譜數(shù)據(jù)鑒定其結(jié)構(gòu)。結(jié)果 分離得到5個(gè)化合物，分別鑒定為2α,3β,19α-三羥基烏蘇-12-烯-23-羧酸-28-O-β-D-吡喃葡萄糖酯（1）、2α,3β,19α-三羥基烏蘇-12-烯-28-酸（2）、2α,3β,19α-三羥基烏蘇-12-烯-23,28-二酸（3）、pseudosanguidiogenin A（4）、β-谷甾醇（5）。結(jié)論 所有化合物均為首次從該植物中分離得到。

Objective To study the chemical constituents in the chloroform fraction from the roots and rhizomes of Rubus reflexus var. lanceolobus. Methods The chemical constituents were separated and purified by silica gel column chromatography and recrytallization, and their structures were identified by physicochemical characteristics and spectral features. Results Five compounds were isolated and identified as 2α,3β,19α-trihydroxyurs-12-en-23-carboxyl-28-O-β-D-glucopyranosyl ester (1), 2α,3β,19α-trihydroxyurs-12-en-28-oic acid (2), 2α,3β,19α-trihydroxyurs-12-en-23,28-dioic acid (3), pseudosanguidiogenin A (4), and β-sitosterol (5). Conclusion All the compounds are isolated from this plant for the first time.
