Abstract:
Ampelopsis grossedentata is a traditional medicinal and edible plant rich in bioactive compounds. This paper focus on the white powder on the surface of A. grossedentata, and the effects of processing technology and storage time on the composition of bioactive compounds in Ampelopsis grossedentata extracts (AMP). 33 compounds in AMP were identified and 30 compounds were reported for the first time compared with standards by UHPLC-Q-Orbitrap-MS. Organic acid, phenol, and flavonoids were detected in powder samples. Through comparing the mass spectrum data of three processing samples (traditional method, fermentation and drying-only), five compounds in fermentation samples were higher than other groups, and the content of most compounds of the traditional process was decreased compared with drying-only process. For the storage time research, the powder on the surface was found to be more unstable than leaf parts after 24 h, suggesting that sealing preservation is crucial in the process after powder precipitation.
