PHARMACOGNOSTIC STUDY OF ZIZIPHUS MAURITIANA LAM. (RHAMNACEAE)
Journal Title: International Journal of Pharmacognosy - Year 2018, Vol 5, Issue 6
Abstract
Objective: To study the preliminary and pharmacognostic characteristics of Ziziphus mauritiana Lam., harvested in Côte d'Ivoire. Identify the drug by anatomy and histochemistry. Method: Macroscopic and microscopic study of the fresh and dry drug and determination of physico-chemical parameters. Results: Tree, shrub or bush, 16 m long, 5 m or 4 m, Ziziphus mauritiana Lam. Has bending branches with rounded tops. Its fairly cracked bark is gray or brown, then pale red. The oval or sub-orbicular leaves are alternate and petiolate from 4 mm to 5 mm. The limb, dark green in color, is polished on the upper side and whitish and then densely to mentose on the lower side. The anatomo-histological cut of the limb showed a median rib slightly curved on the upper surface and strongly bulging on the lower side and a broader limb. Each epidermis, consisted of small, visible cells more or less rectangular, is covered with cuticle, outer lipoidal covering; impermisive and resistant, giving it a protective role. The cross section of the stem, revealed a quadrangular shape, has two distinct zones: the bark and the central cylinder. The less developed bark comprises of 4 tissues (cuticle, epidermis, collenchyma and cortical parenchyma). The central cylinder, more developed than the bark, is composed of primary tissues (bone, wood, medullary parenchyma, sclerenchyma and peri-medullary fiber). The sclerenchyma occurs in small clusters around the conductive system. Conclusion: Pharmacognostic analysis and physico-chemical characteristics can help in the efficient utilization of this medicinal plant.
