| Abstract: |
| Compounds were separated by various chromatographic techniques to study the chemical constituents of the air part of Tadehagi trquetrum. Their structures were identified by analyzing their physicochemical properties and spectral data. The results showed that thirteen compounds were purified and determined as kaempferol(1),kaempferol-3-O-α-L-rhamnoside(2),kaempferol-3-O-β-D-glucoside(3),kaempferol-3-O-β-D-rutinoside(4),quercetin-3-O-α-L-rhamnoside(5),kaempferol-3-O-α-L-rhamnoside(1→6)-β-D-galactopyranoside(6),querceitin-3-O-β-D-glucopyranosi(7),quercetin-3-O-α-L-rhamnoside(1→6)-β-D-galactopyranoside(8),rutin(9),phloroglucinol-1-O-β-D-glucopyranoside(10),naringenic acid(11),roseosideⅡ(12),(+)-catechin(13). Compounds 2, 4, 5, 6, 8, 9, 10, 12 were isolated from Tadehagi trquetrum for the first time. |
