METABOLOMIC PROFILE BUPLEURUM SCORZONERIFOLIUM WILLD., GROWING IN THE BAIKAL REGION

Abstract

In folk medicine in the Baikal region, an infusion from the aerial part of the plant Bupleurum scorzonerifolium (Willd) is widely used as a choleretic and anti-inflammatory agent. The choleretic effect of herbal remedies is mainly due to the content of phenylpropanoids and flavonoids. Using high performance liquid chromatography with a diode-matrix detector and 3Q electrospray ionization detector, we studied the metabolic profile of the phenylpropanoids and flavonoids of the aboveground organs of B. scorzonerifolium (Willd.), which grows in the Baikal region. In the aboveground organs of B. scorzonerifolium, 7 phenylpropanoids and 17 flavonoids were identified, of which 15 compounds for the species were identified for the first time. Quantitative determination of individual components was carried out in the aboveground organs of B. scorzonerifolium and dry extract by microcolumn HPLC with UV detection. The predominant components in the aerial part of the plant are 5-O-caffeic quinic acid, 3,5-di-O-caffeic quinic acid, isoquercitrin, isorhamnetin-3-O-glucoside, kaempferol-3-O-rhamnoside and rutin. The dry extract obtained from the aerial part of B. scorzonerifolium contains the entire complex of phenylpropanoids and flavonoids, which are identified in the plant. The content of active ingredients in the extract is 2.5–3.0 times higher than in the aboveground organs. The aboveground organs and dry extract of B. scorzonerifolium can be used as a source of phenylpropanoids and flavonoids.
