Abstract:
To establish a determination method for the contents of ammonium glycyrrhetate,nardosinone,and curcumin in transdermal receptor liquid of Baimai Ointment,and investigate the percutaneous permeability of Baimai Ointment and the effects of two kinds of penetration enhancers on percutaneous absorption of three components. The contents of ammonium glycyrrhetate,nardosinone,and curcumin in transdermal receptor liquid were determined by high pressure liquid chromatography( HPLC). The vertical modified Franz diffusion cell was used to perform a transdermal experiment in vitro with the abdominal skin of mice( treated and untreated). The transdermal receptor liquid was preferably used to investigate the transdermal absorption rule of the Baimai Ointment and the effect of the penetration enhancer. The results showed that the comprehensive solubility of PEG-ET-NS( 3 ∶3 ∶4) was best among three types of receptor liquid PG-ET-NS( 3 ∶3 ∶4),PEG-ET-NS( 3 ∶3 ∶4),ET-NS( 3 ∶7). PEG-ET-NS was used as the receptor liquid for in vitro transdermal experiments. The cumulative permeation area of ammonium glycyrrhetate,nardosinone and curcumin within 24 h was 5. 73,18. 99,0. 38 μg·cm~(-2)respectively. Taking QEFand ER as comprehensive evaluation indicators of permeation performance,the comprehensive penetration-promoting performance of ammonium glycyrrhizinate: 3% PEG 400-ethanol-normal saline ≈ 1. 19 times( 3%azone) = 1. 94 times( blank); comprehensive penetration-promoting performance of nardosinone: 3% PEG 400-ethanol-normal saline≈1. 28 times( 3% azone) = 1. 37 times( blank); the comprehensive penetration performance of curcumin: 3% PEG 400-ethanol-normal saline≈1. 77 times( 3% azone) ≈3. 42 times( blank). The comprehensive penetration enhancement properties of the two penetration enhancers were as follows: 3% PEG 400-ethanol-normal saline>3%azone>blank. The transdermal absorption curve of ammonium glycyrrhetate,nardosinone and curcumin in Baimai Ointment were consistent with the zero-order equation,indicating that the transdermal absorption process was irrelevant to the concentration of three components,and its was a diffusion process. This experiment provides reference for the study of ointment transdermal preparations.
