Abstract: Based on the morphological characteristics and phylogenic analysis,endophytic strain WXC isolated from the seed of Trewia nudiflora was classified as Streptomyces sp.The fermentation products of strain WXC showed antifungal activity.Bioactivity-guided fractionations resulted in the isolation of two pyran naphthoquinone compounds,using column chromatography.The structures of compounds 1 and 2 were elucidated respectively as frenolicin B and deoxyfrenolicin according to spectroscopic analyses including NMR and MS.

Key words: endophytic, Streptomyces sp.WXC, isolation and purification, structure
