Abstract

  Recently we have noted anti solar activity of ethanol extract of Ageratum conyzoides Linn (A. conyzoides L.) leaves. We did extraction of the plant leaves to establish this pharmacological activity. As it is known that pharmacological activity of a plant depends on temperature and time of extraction process, aim of the present work was to see effects of temperature and time of the extraction process on anti solar activity of ethanol extract of A. conyzoides L. leaves. A. conyzoides L. leaves were collected and identified by the taxonomist. Ethanol extracts of the leaves were prepared separately at temperatures 20, 37, 55, 70 degree centigrade for 10, 15, 30, 50 minutes. Anti solar activity of different extracts was checked by a spectrophotometer taking absorption in UV region (200 - 400 nm) at 10 nm intervals. Results showed that ethanol extract of A. conyzoides L. leaves at 370C for 15 minutes showed maximum anti solar activity. These conditions may be maintained for isolation work of the anti solar compound from A. conyzoides L. leaves.
