ABSTRACT
Objective To explore the extraction kinetic deviation of the chlorogenic acid (ChA) in Lonicerae Japonicae Flos and Lonicerae Flos through established extract kinetic model of closed system of Chinese materia medica. Methods The content of ChA (W0) and ρ2in Lonicerae Japonicae Flos and Lonicerae Flos were determined by HPLC; The V1and V2were measured by water absorbing further to calculate V0; The value of M, N, L, α, β, and π were estimated by curve fitting using SPSS19.0 edition; The extraction kinetic parameters k, k1′, k2′, ρ1, tmax, cmax, AUC, P%, and D% were calculated by Excel; their similarity was calculate by the total quantum statistical moment similarity (TQSMS). Results The V0, V1,and V2for Lonicerae Japonicae Flos were 18.69, 9.50, and 30.20 mL, respectively. The W0for the ChA in Lonicerae Japonicae Flos were 3.75%, and ρ2was 0.884; The V0, V1, and V2for Lonicerae Flos were 12.79, 7.80, and 37.00 mL, respectively. The W0for the ChA in Lonicerae Flos were 5.67%, and ρ2was 1.020; The extraction kinetic profiles for ChA in Lonicerae Japonicae Flos and Lonicerae Flos were fitted three compartment model. The main kinetic parameters as k were 0.1101, 0.3755 h-1; k1′ were 3.632, 3.288 h-1; k2′ were 53.12, 55.28 h-1; ρ1were 2.731, 2.751; tmaxwere 0.299 5, 0.216 3 h; cmaxwere 0.134 0, 0.252 7 mg/mL; AUC were 3.405, 1.560 h; P% were 35.73% and 44.57%; D% were 0.916 2% and 2.680 7%, respectively. Their TQSMS was 0.963 8, which indicated that the extraction kinetics of ChA in Lonicerae Japonicae Flos and Lonicerae Flos had good similarity. Conclusion The extraction kinetic model described the dissolution behavior and deviation of extraction kinetic profiles for ChA in Lonicerae Japonicae Flos and Lonicerae Flos objectively and effectively. This research can provide some references for further study on extraction processes and preparation of Lonicerae Japonicae Flos and Lonicerae Flos.
