PHYTOEXTRACTION POTENTIAL OF INORGANIC SOLVENTS FOR SECONDARY METABOLITES OF SOME PLANTS FROM CHOLISTAN DESERT, PAKISTAN
Ghulam Yasin
Abstract
The present studies were aimed to solvent based extracted phytochemicals indices for the trees and herbs of Cholistan desert, Pakistan. Among phytochemicals secondary metabolites like alkaloids, flavonoids and saponins were studied. Phytochemicals are synthesized in response to environmental stresses. Quantification of these metabolites in three different solvents Ethanol, Methanol and Acetone was carried out from various plants. Quantifications of alkaloids, flavonoids and saponins were done in shoots of trees and herbs. The results revealed that alkaloid contents in different solvents were as Ethanol > Methanol >Acetone. The mean alkaloid contents in some trees of Cholistan desert were in the order of Acacia jacquemontii>Tamarix aphylla>Acacia nilotica>Capparis decidua>Prosopis cineraria among trees. The maximum alkaloids were found in Citrullus colocynthis and minimum in Tribulus longipetalus among herbs. The order of solvent for flavonoid extraction was Methanol >Ethanol >Acetone. The order of plants for flavonoids was as Acacia jacquemontii>Capparis decidua>Prosopis cineraria>Tamarix aphylla>Acacia nilotica. Maximum flavonoids, among herbs, were in Solanum surattense and minimum in Launaea nudicaulis. When summarized, the results revealed as Methanol >Ethanol >Acetone as order for saponins. The maximum concentrations of saponins were found in Acacia jacquemontii and Tribulus longipetalus of trees and herbs respectively.
