| 摘要 目的：研究大瑶山甜茶正丁醇部位中的二萜类化学成分，为探索其活性物质奠定基础。方法：采用95%乙醇提取药材，提取液回收至无醇味后溶于水中，依次用石油醚、乙酸乙酯和正丁醇萃取，减压干燥后获得相应萃取物，综合运用各种色谱技术对正丁醇萃取物进行分离纯化，获取二萜类化合物，通过NMR对得到的化合物进行结构鉴定。结果：从大瑶山甜茶中分离得到10个二萜类化合物，分别鉴定为7β, 17-dihydroxy-16β-ent-kauran-19-oic acid 19-O-β-D-glucopyranoside ester (1), 7β, 17-dihydroxy-ent- kaur-15-en-19-oic acid 19-O-β-D-glucopyranoside ester (2), 13-[(O-β-D-glucopyranosyl)oxy]ent-kaur-16-en-19-oic acid 2-O-β-D- glucopyranosyl-β-D-glucopyranosyl ester (3), 12-α-[(2-O-β-D-glucopyranosyl-β-Dglucopyranosyl)oxy]ent-kaur-16-en-19-oic acid β-D- glucopyranosyl ester (4), glaucocalyxin G (5), β-D-glucopyranosyl 17-hydroxy-ent-kauran-19-oate-16-O-β-D-glucopyranoside (6), cussoracosides E (7), 17-O-β-D-glucopyranosyl-16α-ent-kauran-19-oic acid (8)，cussovantoside A (9)，cussovantoside C (10)。结论：化合物1-10首次从大瑶山甜茶中分离得到。 |

| ABSTRACT Objective: To study the diterpenoids of n-butanol extract of Rubus suavissimus S. Lee., and to establish the foundation for its active substances. Methods: The medicinal materials were extracted by 95% EtOH. The extract was recovered to non-alcoholic taste and dissolved in water. The extract was successively extracted with petroleum ether, ethyl acetate and n-butanol. After drying under reduced pressure, the corresponding extract was obtained, and the n-butanol extract was separated and purified by various chromatographic techniques. Results: The structures of the compounds were established as 7β, 17-dihydroxy-16β-ent-kauran-19-oic acid 19-O-β-D-glucopyranoside ester (1), 7β, 17-dihydroxy-ent-kaur-15-en-19-oic acid 19-O-β-D-glucopyranoside ester (2), 13-[(O-β-D- glucopyranosyl)oxy]ent-kaur-16-en-19-oic acid 2-O-β-D-glucopyranosyl-β-D-glucopyranosyl ester (3), 12-α-[(2-O-β-D- glucopyranosyl-β- Dglucopyranosyl)oxy]ent-kaur-16-en-19-oic acid β-D-glucopyranosyl ester (4), glaucocalyxin G (5), β-D-glucopyranosyl 17-hydroxy- ent-kauran-19-oate-16-O-β-D-glucopyranoside (6), cussoracosides E (7), 17-O-β-D-glucopyranosyl- 16α-ent-kauran-19-oic acid (8), cussovantoside A (9), and cussovantoside C (10). Conclusion: Compounds 1-10 were obtained from Rubus suavissimus S. Lee firstly. |
