PHARMACOGNOSTIC AND PHYTOCHEMICAL INVESTIGATIONS OF OPERCULINA TURPETHUM LINN. ROOTAbstract
Objective: To study detailed Pharmacognosy of the root of Operculina turpethum (Convolvulaceae) well known Ayurvedic drug (trivrit).
Method: Macroscopy, microscopy, physicochemical analysis, preliminary phytochemical testing of the root and other WHO recommended methods for the standardization were done.
Results: The periderm cells are tabular in shape; the phloem cells are homogeneous, tabular in shape and have suberized walls. The phelloderm cells are also tabular in shape and have cellulose walls. Irregular masses of squarish sclerenchyma cells are seen inner to the periderm and with outer cortical zone. Sclereids are also seen in small masses in the interior portion of the cortex. The cortical cells are densely loaded with starch grains and sparsely distributed calcium oxalate crystals. Secondary xylem is the thick and dense central cylinder comprising wide, circular thin walled vessels and thick walled lignified fibers. The vessels are solitary and diffuse in distribution. The xylem parenchyma cells are thick, tangential layered and they are apotracheal layered type. The parenchyma layers are away from the vessels.
