The twigs and leaves of Pithecellobium clypearia(Jack.)Benth are used as common Chinese traditional herbal medicine to treat upper respiratory tract infection,acute gastroenteritis and bacterial dysentery.The study isolated nine compounds from the EtOAc extract,all of which were obtained from Pithecellobium Mart.for the first time.Based on 1H-NMR and 13C-NMR data,the structures of these compounds,including two ladiosiplodins and two dihydroisocoumarins,were elucidated. 展开更多

Neofusicoccum parvum,an endophytic fungus isolated from Elaeocarpus serratus(Ceylon Olive;family Elaeocarpaceae),was grown for 3 weeks in potato dextrose broth.Chromatographic separation of the ethyl acetate extracts from the culture filtrate and mycelium over silica gel,Sephadex LH-20 and preparative thin layer chromatography furnished(R)-7-hydroxymellein(1),(3R,4R)-4-hydroxymellein(2),(3R,4S)-4-hydroxymellein(3),(R)-5-hydroxymellein(4),(R)-mellein(5),(3R,4R)-4,7-dihydroxymellein(6),(6R,7S)-dia-asperlin(7),CJ-14445(8)and 13,14,15,16-tetranorlabd-7-ene-19,6β:12,17-diolide(9).The structures of known compounds 1–9 were determined by spectroscopic methods and comparison with reported data.This is the first report of the isolation of an endophytic fungus from E.serratus,and the isolation of compounds 1,4,6,8 and 9 from N.parvum.It is important to note that compounds 1–7 are small molecules with an oxygen heterocyclic ring system.These compounds can be used as starting materials in the synthesis of pharmaceutically important large molecules with oxygen heterocyles. 展开更多
