elsewhere that Vigna radiata seeds contain a high concentration of γ-glutamyl- S -methylcysteine and its sulphoxide and that these compounds serve as index compounds for the chemotaxonomy of V. radiata . Beside these two γ-glutamyl peptides, nine other γ-glutamyl derivatives, of which three are new compounds, have been isolated and identified from V. radiata seeds. The structures of the new peptides, γ-glutamyl-
摘要 据其他地方报道,豇豆种子含有高浓度的γ-谷氨酰-S-甲基半胱氨酸及其亚砜,这些化合物可作为辐射豇豆化学分类学的指标化合物。除了这两种 γ-谷氨酰肽之外,还有九种其他 γ-谷氨酰衍生物,其中 3 种是新化合物,已从辐射弧菌种子中分离和鉴定出来。新肽,γ-谷氨酰-S-甲基半胱氨酰-β-丙氨酸(S-甲基高谷胱甘肽)、γ-谷氨酰-Nδ-乙酰鸟氨酸和γ-谷氨酰-γ-谷氨酰-S-甲基半胱氨酸的结构,通过直接比较得到证实与合成标本。其他六种γ-谷氨酰衍生物是高谷胱甘肽、γ-谷氨酰谷氨酸、-天冬氨酸、-苯丙氨酸、-亮氨酸和-异亮氨酸。
