From the branch tissue of Maytenus hookeri, the endophytic strain Lz531 was isolated, and determined to belong to Streptomyces, according to its 16S rRNA sequence. From the extracts of the fermentation broth of Streptomyces sp. Lz531, two new and four known compounds were isolated. The two new compounds were identified as cyclo(L-Pro-L-Val-L-Val) (1) and 13-methyl-N-(2-phenylethyl)tetradecanamide (2).
从云南美登木的枝条组织中分离出内生菌株Lz531，根据其16S rRNA序列确定其属于链霉菌属。从链霉菌属Lz531发酵液提取物中分离出两个新化合物和四个已知化合物。这两个新化合物被鉴定为环（L-脯氨酸-L-缬氨酸-L-缬氨酸）（1）和13-甲基-N-（2-苯乙基）十四酰胺（2）。
