摘要
Background:Spermacoce pusilla Wallich(S.pusilla)is widely used in Guangdong province of China.It has valuable medicinal value in treating trauma,fractures,carbuncle,swelling,and poisonous snake bites.Method:The present study was carried out to provide a scientific basis for the identification and authenticity of S.pusilla with the help of pharmacognostical parameters,which has not been done before.In this study,a series of related identification information such as source,character,microscopic observation,physical and chemical reaction,and molecular markers were employed to establish accurate,comprehensive pharmacognostic identification information of S.pusilla.Results:The study provided some basic data regarding the genuine crude drug.The identification efficiency of ITS sequences obtained in this study is high,the psbA-trnH sequence was obtained from S.pusilla and sequenced for the first time in this study.Conclusion:In this study,traditional pharmacognosy identification and molecular marker identification of S.pusilla in the Guangdong region were carried out,and a systematic and comprehensive pharmacognosy identification information system was established.
