ISOLATION OF PENTANDRAONE FROM METHANOLIC EXTRACT OF AERIAL PART OF ZALEYA PENTANDRA

Abstract

Zaleya pentandra is a well known species in the genus Zaleya. It has wide traditional medicinal uses. Zaleya pentandra is being used for treatment of stomach diseases, respiratory tract infection and cough. For the purpose of isolation from the dried aerial parts of Zaleya pentandra was subjected to extraction with methanol, this combined extract was concentrated and column chromatography was then carried out. The isolation and purification yielded amorphous solid which was subjected to physical, chemical, and spectral techniques like UV, IR, ¹H-NMR, ¹³C –NMR and HREI-MS for the structure elucidation of compound. The compound was concluded as pentandraone, a novel compound isolated for the first time from the methanolic extract of aerial part of Zaleya pentandra.
