원보 : LC-MS/MS를 이용한 반하사심탕 물 추출물 중 13종 성분의 함량분석

Banhasasim-tang is a well-known traditional Korean herbal formula and has been used clinically for the treatment of gastric disease, including acute and chronic gastritis, diarrhea and gastric ulcers in Korea. In this study, an ultra-performance liquid chromatography-electrospray ionization-mass spectrometer method was developed for the quantitative determination of the 13 marker constituents, homogentisic acid (1), 3,4-dihydroxybenzaldehyde (2), spinosin (3), liquiritin (4), baicalin (5), ginsenoside Rg1 (6), liquiritigenin (7), wogonoside (8), ginsenoside Rb1 (9), baicalein (10), glycyrrhizin (11), wogonin (12), and 6-gingerol (13) in Banhasasim-tang decoction. Separation of the compounds 1-13 was using an UPLC BEH C18 (100×2.1 mm, 1.7 μm) column and column oven temperature was maintained at 45℃. The mobile phase consisted of 0.1% (v/v) formic acid in water (A) and acetonitrile (B) by gradient elution. The injection volume and flow rate were 2.0 μL and 0.3 mL/min, respectively. Calibration curves of the compounds 1-13 were showed with r(2) values ≥ 0.9908. The limit of detection and limit of quantification values of the compounds 1-13 were 0.04-1.11 ng/mL and 0.13-3.33 ng/mL, respectively. Among the these compounds, the compounds 1-3 were not detected, while the compounds 4-13 were detected in the ranges of 3.20-107,062.98 μg/g in Banhasasim- tang sample.
