Preliminary phytochemical screening of some plants of ethnobotanical importance from district Gilgit of Northern Areas, Pakistan

ABSTRACT

Seven medicinal plants of ethnobotanical importance belonging to families Elaeganaceae, Gentianaceae, Cupressaceae, Asleraceae, Tamaricaceae, Berberidaceae and Salicaceae were investigated for the presence of alkaloids, amino acids, anthraquinone [free nad as glycosides] ascorbic acid, carbohydrates, coumarins, flavonoids, phenolics, proteins, saponins and steroids in their coumarins, phenolics and proteins. Ephedra gerardiana [stem] [family ephedraceae] tested positive for alkaloids, ascorbic acid, coumarins, phenolics, proteins, saponins and steroids. Tamarix gallica [Family Tamaricaceae] tested positive for alkaloids, amino acids, anthraquinone as glycoside, ascorbic acid, carbohydrates, flavonoids, phenolics, proteins and steroids in stems, roots and leaves. Salix accomophylla [family Silaceae] showed positive results for alkaloids, amino acids, anthraquinone [free and as glycosides] ascorbic acid, carbohydrates, flavonoids, phenolics, proteins, saponins and steroids. Hippophe rhamnoides [family Elaeganaceae] showed positive results for alkaloids, amino acids, anthraquinone [free and as glycosides] ascorbic acid, carbohydrates, coumarins, flavonoids, phenolics, proteins, saponins and steroids. Berberis aristata [family Berberidaceae] showed positive results for alkaloids, amino acids, ascorbic acid, carbohydrates, flavonoids, phenolics, proteins and steroids in stem, roots and leaves, Juniperus excelsa [Family Juniperaceae] showed positive results for anthraquinone [both free and as glycosides], carbohydrates, phenolics, proteins, saponins and steroids
