RESUMO
Certain species of ethnobotanical importance belonging to families Asteraceae, Berberidaceae, Cupressaceae, Elaeagnaceae, Gentianaceae, Salicaceae and Tamaricaceae, were collected from Gilgit during the months of June and July 2008 and were investigated for the presence of alkaloids, amino acids, anthraquinone [free and as glycosides] ascorbic acid, carbohydrates, coumarins, flavonoids, phenolics, proteins, saponins and steroids in their aqueous, ethanol and benzene extracts. Artemisia maritime L. [leaves] showed positive results for carbohydrates, coumarins, phenolics and proteins. Ephedra gerardiana Wall ex. Stapf. [stem] tested positive for alkaloids, ascorbic acid, coumarins, phenolics, proteins, saponins and steroids. Tamarix gallica L. tested positive for alkaloids, amino acids, anthraquinone as glycoside, ascorbic acid, carbohydrates, flavonoids, phenolics, proteins and steroids in stems, roots and leaves. Salix acmophylla Boiss. showed positive results for alkaloids, amino acids, anthraquinone [free and as glycosides] ascorbic acid, carbohydrates, flavonoids, phenolics, proteins, saponins and natural steroids. Hippophae rhamnoides L. showed positive results for alkaloids, amino acids, anthraquinone [free as glycosides] ascorbic acid, carbohydrates, coumarins, flavonoids, phenolics, proteins, saponins and steroids. Berberis glycocarpa Stapf. showed positive results for alkaloids, amino acids, ascorbic acid, carbohydrates, flavonoids, phenolics, proteins and steroids in stem, roots and leaves. Similarly Juniperus excelsa Wall ex. C.A. Meyer showed positive result for anthraquinone [both free and as glycosides], carbohydrates, phenolics, proteins, saponins and natural steroids
