Curcusinol ( 1 ), a new resveratrol trimer, was isolated and identified from the rhizomes of Curculigo sinensis (Hypoxidaceae), together with five known phenolic compounds: curcapital ( 2 ), pilosidine ( 3 ), crassifoside A ( 4 ), curculigoside I ( 5 ) and phegopolin ( 6 ). The new compound 1 was determined as an oligostilbenoid on the basis of various spectroscopic methods, especially intensive 2D‐NMR (COSY, HMQC, HMBC and NOESY) techniques. 相似文献
