摘要
A new indolinepeptide (3) was isolated, together with two known compounds, a cerebroside (1) and an alloxazine (2), from silkworm larvae infected with Paecilomyces sp. J300. On the basis of spectroscopic data, their structures were elucidated as (4E, 8E, 2S, 2'R, 3R)-N-2'-hydroxyhexadecanoyl-1-O-beta-D-glucopyranosyl-9-methyl-4, 8-sphingadienine (1), 7,8-dimethylalloxazine (2) and 3beta,5-dihydroxy-1-N-methyl-indoline-2beta-carbonyl amino-D-alanyl-erythro-p-hydoxyisoleucinyl-glycine (3).
