The Qinling-Daba Mountains area is the main producing areas of Gynostemma longipes for medicinal usage, and samples of wild whole plants in Pingli, Shaanxi Province and Qingchuan, Sichuan Province were collected. The ultra-high performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry(UHPLC-Q-TOF-MS~E) was used to profile the chemical compositions and analyze the similarities and differences of G. longipes samples in these areas. Based on the accurate molecular weight and fragment information obtained from Q-TOF-MS~E, the structures of the main components were identified by combining with the mass spectra, chromatographic behaviors of reference standards and related literatures. The results showed that the components of wild G. longipes from different places among Qinling-Daba Mountains area were similar. Forty-five chemical components were identified in the whole plant of G. longipes from Pingli, Shaanxi Province, including 43 triterpenoid saponins and 2 flavonoids which contain all main peaks in its fingerprint. The main components are dammarane-type triterpenoid saponins, such asgypenoside ⅩLⅨ, gypenoside A and its malonylated product of glycosyl.

OBJECTIVE: To explore the new quality problems of Draconis Sanguis imported from Indonesia. METHODS: According to the quality standard of imported medicinal materials and Ch.P method, exploratory analysis was carried out on 10 batches of imported Draconis Sanguis and three batches of Draconis Sanguis fruits. RESULTS: The dracohodin content in three batches of Draconis Sanguis fruits was 1.2%-2.4%. Three batches of imported Draconis Sanguis were obtained by directly pulverization of Draconis Sanguis fruits, and loureirin A and loureirin B were detected in one batch of Draconis Sanguis, suggesting that dracaena cochinchinensis was added. CONCLUSION: Among the 10 batches of imported Draconis Sanguis, three batches are determined to be unqualified due to character inconformity, and the other batch is judged to be unqualified due to the addition of dracaena cochinchinensis.
