Chemotaxonomic variability in Zizyphus mouritiana varieties and its pharmacological properties in relation to human health.

Abstract

Twenty varieties of ber (Zizyphus mouritiana), namely umaran, katha, bilayati, kaithli, ZG-3, gola, safeda rohtak, takadi, tikari, banarasi karaka, seo, sonaur-2, sonaur-3, ilaichi, mundia murahra, pathan, kakrola gola, seb, golden yellow and chhuhara, were investigated for the presence of phenolic acids in stem bark, leaves and fruits using high performance liquid chromatograph. Results indicated the presence of tannic (retention time (Rt.) 2.76 min), gallic (Rt. 2.86 min), caffeic (Rt. 3.12 min), vanillic (Rt. 3.26 min), ferulic (Rt. 3.42 min), chlorogenic (Rt. 4.16 min) and cinnamic acids (Rt. 4.45 min) in varying amounts in different parts in of these varieties. In fruits of seven varieties, namely, kaithly, sonaur-2, sonaur-3, mundia murahra, pathan, golden yellow and chhuhara, oxalic acid (Rt. 3.00 min) was also detected. Pharmacological properties of phenolic acids of fruits in relation to human health and the possible implications of different phenolic acids in chemotaxonomy of different varieties of ber are discussed.
