This study was to evaluate the efficiency of different solvent systems to extract active ingredients from different parts of medicinal plants used as oriental medicinal herb in the cosmetic industry. We tested efficacies related to the antioxidative effects and UV absorption of herbal extracts as complex of active ingredients, not each single ingredient. When extracting medicinal plant which is used effective medicine, we should consider the collecting conditions like collecting time, place, part and extracting conditions like solvent, temperature, time, and etc. Among them, extraction solvent and collecting part are very important factors for the efficacy. As increased interest in medicinal plants, more intensive studies on collecting conditions and extracting processes were needed for the developments in the herbal ingredient industry. We evaluated the efficiency of different solvent systems to extract active ingredients from different parts of plants (Terminalia chebula, Syzygium aromaticum, Paeonia lactiflora, Morus alba, Scutellaria baicalensis) widely used as medicine and food. As results, we found that proper condition can make better data and decrease the required quantity.
