Abstract

To investigate the effects of four original constituents (Loganin, Morroniside, Peoniflorin, Paeonol) of Liu-wei Di-huang pills on the proliferation and differentiation of rat preadipocyte, and optimize the best concentration by the orthogonal test. The rat preadipocytes were cultured, then above four original constituents according to 4 factors and 3 levels to make L9 (3(4)) orthogonal test, and the control was performed at the same time. The proliferation of preadipocytes was determined by MTT method, and the accumulation of cellular lipid was determined by Oil Red O staining, the differences between factors and variances were compared by the value of absorbance. The combination of four original constituents of Liu-wei Di-huang pills could stimulate rat preadipocyte proliferation and inhibited its lipid accumulation. Both the effects were highly significant (P < 0.01) with the combination of A3 B1 C3 D2; Compared with the monosomic group, the effects of the A3 B1 C3 D2 was highly significant (P < 0.01). Compared with the monosomic group, the effects of the combination of the four original constituents of Liu-wei Di-huang pills on the proliferation and differentiation of rat preadipocyte were highly significant. This combination consists of Loganin, morroniside with high doses, Paeonol, Peoniflorin with mid-dose and low-dose, respectively. Regnesent the overall regulatory role of synergy and officiencg.
