Objective:To evaluate the quality of Arnebiae Radix(AR)and dictamni Cortex(dC)and study the efficacy of herbal extracts of these two herbs on the treatment of allergic contact dermatitis(ACd).Methods:Qualitative and quantitative analysis of effective components was performed using High Performance Thin Layer Chromatography(HPTLC),High Performance Liquid Chromatography(HPLC),and HPLC-Quadrupole Time of Flight-Mass Spectrometry(HPLC-QTOF-MS).In vitro allergic ACd 3d model was established by incubating 3d reconstructed human epidermis(RHE)with skin sensitizer,potassium dichromate.A total of 65 gene expression that were associated with ACd,which included 24 antioxidant responsive element(ARE)and 41 SENS-IS genes were quantified by q *** than or equal to 10 ARE genes and 18 SENN-IS genes were induced by 1.3-fold,demonstrating the successful establishment of in vitro ACd *** extracts of AR and dC were applied on the in vitro ACd model to study the ***:Batch 3 of AR and batch 2 of dC showed presence of all active ingredients with the highest *** ingredients of the herbs were extracted using a special oil and formulated into herbal oil *** herbal oil extracts were able to down regulate the induced genes in the in-vitro ACd skin model,bringing the tissue back to homeostatic ***:The oil extracts showed the potent efficacy of using AR and dC in ACd *** combination study will be done to optimize the formulation ratio which will be developed into a topical cream.
