    Abstract:

    Components of the Lespedeza cuneate from three different months were extracted by ultrasonic alcohol extraction method, the extractives were dissolved by ether and analyzed by GCMS, and quantitative analysis of lupenone by GCMS. Results showed that 61 components have been detected. Lespedeza cuneate included 42 components in May, 39 components in August and 42 components in November. The mainly include alkane, terpenoid and aromatics. The lupenone was firstly found in Lespedeza cuneate, and the relative contents of lupenone in May, August and November were respectively 1.734mg/g, 2.235mg/g and 1.111mg/g. Through comparison the Lespedeza cuneate constituents and contents of the three different months, the Lespedeza cuneate constituents was the least in August, but the contents of it is the highest.
