In this paper, we study the effects of Tongmai Fang, a compound of daidzein, daidzein, 5-hydroxymyristin, manganoside, daidzin, 3’-methoxy puerarin, genistein, O-β-D-glucopyranoside, formononetine-7-O-β-D-glucopyranoside, Furanosyl- (1 → 6) -O-β-D-glucopyranoside, albuterol, Gehuanen, daidzein -7,4’-di-O-β-D-glucopyranose Glucosyl- (1 → 6) -O-glucosyltransferase, puerarin, thaumatoxylin, 3’-hydroxy puerarin, β-D-glucopyranoside, genistein -8-C-β-D-furanosyl- (1 → 6) -O-β-D-glucopyranoside, -β-D-furanosyl- (1 → 6) -O-β-D-glucopyranoside, 3’-hydroxy thaumatan, 6 "-O-β-D-xylosylpuerarin , Biochanin A-8-C-β-D-furanosyl- (1 → 6) -O-β-D-glucopyranoside, ’-di-O-β-D-glucopyranoside, daidzein -7-O-β-D-glucopyranosyl- (1 → 4) -O-β-D-glucopyranoside and soybean Aglycone-7-O-α-D-glucopyranoside (1 → 4) -O-β-D-glucopyranoside in intestine.Using the human intestinal Caco-2 cell monolayer model, we studied the above 25 isoflavones From the villus surface (AP side) to the basal side (BL side) or from the BL side to the AP side of the two directions of transport.Application of high performance liquid chromatography, UV detection of compounds were quantitative analysis of apparent permeability coefficient (P_ (app)), and compared with the positive control drug propranolol and atenolol.The P app of daidzein and tomanonetin from AP side to BL side were (2.55 ± 0.03) × The average values ​​of P app from BL to AP were (2.62 ± 0) × 10 ~ (-5), (3.06 ± 0.01) × 10 ~ (-5) cm · s -1 -5), (2.65 ± 0.11) × 10 -5 cm · s -1, respectively.Compared with propranolol, which is a good positive control in the Caco-2 cell monolayer model P (app) was (2.66 ± 0.32) × 10 ~ (-5) cm · s ~ (-1), and Pare (app) was 2.34 ± 0.10 × 10-7cm · S ~ (-1), the daidzein and the formononetin were in the same order of magnitude as those of propranolol; the other compounds were in the same order of magnitude as atenolol.Application of AP_ (app AP → BL) / P_ (app BL → AP) were 0.97 and 1.15 respectively. It can be predicted that daidzein and formononetin can passively enter the body through intestinal epithelial cells and are well-absorbed compounds; other compounds belong to malabsorptive compounds. O-β-D-furanosyl- (1 → 6) -O-β-D-D-glucosyltransferase P_ (app AP → BL) / P_ (app BL → AP) of glucopyranoside were 0.18,0.28,0.45,0.38,0.49, respectively. It is speculated that they may have efflux mechanism in Caco-2 cell monolayers.
