Ohba. and Terminalia catappa L. showed higher activities of SOD-like and total antioxidant. The analytical method of HPLC chromatographic fingerprint of Rhodiola crenulata H. Ohba. was established and validated. It could be used as the quality control method in the development of these Chinese herbs. Rhodiola crenulata H. Ohba. and Terminalia catappa L. 5% aqueous extract fluid showed no toxicity and no skin and eye irritation response. The evaluation protocols followed OECD Guidelines for Testing of Chemical. This study focused on Rhodiola crenulata H. Ohba. and Terminalia catappa L. which prepared theirs cream dosage form. The stability studies of the cream were performed under 25 and 35℃ for 90 days.
