内生链霉菌Streptomyces sp.Ly221的次生代谢成分
Metabolites from Endophytic Streptomyces sp. Ly221
摘要
Abstract
The strain Ly221 was isolated from the branch tissue of Maytenus hookeri and determined to be a member of Streptomyces according to the 16S rDNA sequence. The extracts from the fermentation broth of Streptomyces sp. Ly221 were purified,and five compounds were obtained. They were identified to be 4,10-dihydroxy-10-methyl-dodec-2-en-l ,4-olide (1) , two diastereomeric 4,11 -dihydroxy-10-methyldodec-2-en-1, 4-olides (2/3 ) , 4-hydroxy-10-methyl-l 1-oxo-do-dec-2-en-1 ,4-olide(4) and N-acetyltyramine(5) based on spectral data,respectively.关键词
