Abstract

The seasonal variation of alkaloids, amino acids and protein have beeninvestigated in leaves of Asparagus racemosus wild ,Boswellia serrateRoxb., Dolichandrone falcata Seem, Grewia tiliaefolia Vahl., Lanneacoromandelica (Houtt.)Merr., Mytenus emarginata (Wilid)D.Hou.,Rhus mysurensis Heune., Securinega virosa Roxb.,Wrightia tinctoriaR.Br. and Zizyphus glabrata Heyne, which are medicinally importantplants of Laling forest. The leaves of Asparagus racemosus showedhigh level of alkaloid content (range 0.641 to 0.772 mg/g dry wt.) andlowest amount of alkaloid content in the leaves of Securinega virosa(0.129 to0.208 mg/g dry wt.) comparatively as compared to otherinvestigated taxa. Comparative account of protein content of leaves of Wrightia tinctoriashowed higher level (range 2.422 to 2.824 mg/g dry wt.) and lowest amount of proteincontent in the leaves of Rhus mysurensis (range 1.224 to 1.526 mg/g dry/wt.). The leaves ofMytenus emarginata showed high level of amino acid content ( range 3.752 to 4.476mg/g/drywt.) and lower amino acid content of Dolichandrone falcata ( range 1.226 to 1.426 mg/g drywt.) comparatively other investigated taxa.

Keywords: Alkaloid, amino acids, protein, medicinal plant and Laling forest.
