摘要：

We have characterized and studied the biological functions of a terpenoid derivative in the Indian tropical tasar silkworm, Antheraea mylitta reared on the primary host plant Arjun, Terminalia arjuna. The compound from insect cocoon turned out to be a terpenoid derivative which resembled oleanane type triterpene (Arjunolic acid) present in the host plant. The plant and cocoon compounds were anti-oxidative as determined by bleaching of beta carotene it? vitro. UV-exposure is the major form of peroxidative insult encountered by this wild tropical silkworm. The life cycle comprising five larval stages and the cocoon stage lasts for about 30-45 days. Hence the sequestration of antioxidant and UV-protectant molecule from the host plant commands great biological significance. (c) 2006 Elsevier Ltd. All rights reserved.
