To evaluate the antioxidative activity of the ethanol extracts from 116 domestic medicinal plants, each extract was added to palm oil and lard in 1,000 ppm level, and the induction time was measured by Rancimat method. Almost all plant extracts tested showed more or less antioxidative activity. The extracts which had strong antioxidative activity to palm oil and lard were Caesalpinia sappan L., Paeonia japonica Miyabe et Takeda, Dendrobium moniliforme (L.) Sw and Crcumae longa L. These extracts were fractionated with chloroform, ethyl acetate, butanol and water. Ethyl acetate layer of Caesalpinia sappan L. and Paeonia japonica Miyabe et Takeda showed marked antioxidative activity, and chloroform layer of Dendrobium moniliforme (L.) Sw and Crcumae longa L. ethanol extract had stronger antioxidative activity than all the other layers.
