Ompounds in VIVEMA TWIN by HPLC-ESI-FTMS. Every chemical compound is reported in Table 2. few assays are in a position to detect and quantify these molecules selectively. In this context, the pH differential system is in a position to locate the presence of anthocyanin compounds thanks to their traits to display various color based in the pH in the environment mixture14,24. The 4-(Dimethylamino)-cinnamaldehyde (DMAC reagent) can selectively react with flavonol compounds with no cost metaoriented hydroxyl groups within the flavonoid scaffold, and using a single bond in 2,3position from the Cring14,24,25. The spectrophotometric determination obtained by way of these assays showed that, even though no anthocyanins were present (LOD: 3 g mL-1; LOQ: ten g mL-1), virtually 17 from the mixture consisted of flavan-3-ols. To be able to determine essentially the most vital active compounds present in VIVEMA TWIN, HPLC-ESI-FTMS was employed. According to each the fragmentation pattern of every single compound and on their retention time, HPLC-ESIFTMS evaluation allowed the putative identification of 16 compounds (Fig. 1). Among the NPY Y4 receptor Agonist custom synthesis identified compounds, four are organic acid [Mannuronic Acid (#1), Gallic Acid (#2), Valoneic Acid (#3) and Phloionic Acid (#14)], 3 are condensed tannins derived in the condensation of GA (#4, #5 and #6) and three are the lactone form with the #3 [Ellagic Acid (#7), Valoneic acid (#8), and 2,3,8-Trimethylellagic Acid (#15)]. In distinct, among the lactones, #8 is a dilactone. Additionally, the HPLC-ESI-FTMS analysis identified other bioactive compounds, for example a caffeic acid derivatives (#13), a single flavonoid (#9), a single lignan (#11) and two organic steroids (#12 and #16).
