CHEMICAL INVESTIGATT ON OF SOME LABIATAE PLANTS OF PAKISTAN

Abstract

Acetone extract of Teucrium royleanum and Teucrium stocksianum of Labiatae family was subjected to various chromatographic techniques for the separation and purification of different components. Four pure compounds (pentatriacontanone(4), hentriacontadien-1-ol(6), (Z)-12-nonadecen- 9-one ( 10) and 5,23-stigmastadien-3-0-galactoside(12)) from Teucrium royleanum and one pure compound (5,22-stigmastadien-3-ol(13)) from Teucrium stocksianum were isolated. Eight components (mixture of triactoane, hentriacontane(l), hentriacontane, tritriacontane, pentatriacontane( 2), tetracosylester and its higher homologues(3) octylester and its higher homologues(5) triterpenes(7), mixture of 5,22,25-stigmastatrien- 3- 01 and 5,25- stigmastadien- 3- 01(8) mixture of octadecanoic acid methylester and octadecadienoic acid methylester(9) and hexacosanoic acid and its higher homologues(ll»were isolated from Teucrium royleanum. Structures 1 13 W4re identified with the help of IR, H-NMR, C-NMR and MS spectroscopy.
