云南美登木共生放线菌菌株3C产生的苯丙素类化合物

摘要

从云南美登木共生放线菌菌株3C的发酵提取物中分离得到两个苯丙素类化合物1和2.通过谱学特征鉴定了化合物的结构,其中,化合物2为新化合物.通过乙酰化反应得到了相应的乙酰化产物,并通过纸片扩散法测定了所有化合物的抗细菌活性.%Two phenylpropanoids(1 and 2)were isolated from the fermentation extracts of commensal microbe of Maytenus hookeri(Streptomyces sp.3C).Their structures were elucidated on the basis of NMR and EIMS techniques and compound 2 was a new one.Their acetylated products,1a,1b and 2a,were obtained by acetylation with Ac2O-pyridine.The antibacterial activities of all the five compounds were performed by paper-disc assay method,and potential activities were observed.
