Abstract

High altitude herbal medicines offers remedy for many diseases, particularly for which no medicine is available. As high altitude plants grow under stressful situations and exposed to high UV radiations, they are reported to have immense potential. Various scientific studies conducted on Hippophae species (Elaeagnaceae) during the last decade confirm its medicinal values. The present study was carried out with a view to lay down standards which could be useful to detect the authenticity of these medicinal plants, further the microscopical and physiochemical evaluation were studied to reveal the differences among Hippophae rhamnoides L. and Hippophae salicifolia D. Don. For the microscopic observation, free hand cross sections of the leaves of Hippophae rhamnoides and Hippophae salicifolia were stained with phloroglucinol and hydrochloric acid (1:1) and studied according to standard methods. Physiochemical analysis was carried out as per WHO guidelines on quality control methods for medicinal plants. The cross section of both the species of leaves were almost similar and revealed that the lower epidermal cells were completely covered with apressed stellate trichomes and abundant sunken stomata. Ash values of Hippophae rhamnoides leaves, showed higher ash content, compared to Hippophae salicifolia. The Pharmacognostic and phytochemical profile of Hippophae rhamnoides and Hippophae salicifolia are highly dependent on environmental adaptability of the plants. The present study helps in identification and differentiation of both the species of Hippophae.
