| 摘 要： | 从中国民间草药短瓣花（Brachystemma calycinum D.Don)干燥根的乙醇提取物中分离得到4个新的微量环八肽，命名为短瓣花环肽A、B、C和D。经光谱分析鉴定。它们的结构分别为cyclo(Pro^1-Phe-Leu-Ala^1-Thr-Pro^2-Ala^2-Gly)(1)、cyclo(Pro^1-Ala-Phe-Trp-Asp-Pro^2-Leu-Gly)(2)、cyclo(Pro^1-Ⅱe-Gly-Pro^2-Val-Ala^1-Ala^2-Tyr)(3)和cyclo(Pro-OMet-Trp-Ⅱe-Gly-Ala-Leu-Asp)(4)。

New Minor Cyclic Peptides from Brachystemma calycinum |
| |
| Abstract: | From the ethanol extract of the roots of Brachystemma calycinum D.Don, a Chinese folk herb, four new minor cyclic peptides namely brachystemin A, B, C and D (1-4) have been isolated. Their structures were established as cyclo (Pro 1_Phe_Leu_Ala 1_Thr_Pro 2_Ala 2_Gly) (1), cyclo (Pro 1_Ala_Phe_Trp_Asp_Pro 2_Leu_Gly) (2), cyclo (Pro 1_Ile_Gly_Pro 2_Val_Ala 1_Ala 2_Tyr) (3) and cyclo (Pro_OMet_Trp_Ile_Gly_Ala_Leu_Asp) (4) respectively by means of extensive spectral methods. |
