%X Diospyros malabarica (Desr.) Kostel synonym Diospyros peregrina Gurke (Family: Ebenaceae) is a medium sized evergreen tree commonly known as Kendu in Assamese. The plant has ethnomedicinal significance and used by various ethnic communities of North-East India to treat various disorders like dysentery, diabetes, diarrhea malaria, ulcer and wounds. However, detailed scientific information is not available to identify the plant material, in order to ascertain its quality and purity. Therefore, the present work was carried out to perform morpho-anatomical and physicochemical analysis of D. malabarica stem bark. The bark is externally dark brown to black in color and rough having characteristics odor and astringent taste. The microscopy of bark reveals the presence of polygonal thick walled cork, 3-4 layered phellogen, 7-8 layered phelloderm, stone cells, phloem fibers and medullary rays. Stem bark powder showed thick walled cork cells, thick walled elongated phloem fibers, lignified stone cells and rhomboidal crystals of calcium oxalate. Further, physicochemical analysis of the bark power showed loss on drying, total ash, water soluble ash, and acid insoluble ash as 6.2, 5.6, 1.1, 2.45, and 5.7% w/w respectively. The alcohol and water soluble extractives values of the stem bark were 10.6 and 16.8% w/w respectively. The result of preliminary phytochemical screening indicates presence of triterpenoids, saponins, tannins, flavonoids and sterols. The findings of this study will facilitate pharmacognostic standardization of the plant material and aid in the preparation of an herbal monograph for the species.

Kostel synonym Diospyros peregrina Gurke, commonly known as Kendu in Assamese, is a small middle sized evergreen tree belongs to family Ebenaceae (Figure 1). The plant is distributed throughout the tropics and has various ethno-medicinal significances. It is used for the treatment of dysentery, fever, malaria, diabetes, ulcer and wounds 1, 2, 3. The fruit and stem bark possess astringent property and are traditionally used for the treatment of dysentery, diarrhea and intermittent fever & the macerated matured unripe fruit is successfully used in costal West Bengal of India for treatment of diabetes 4, 5. The fruits are also used to dye fishing nets for its durability and attract fishes 6. The alcoholic extract of stem bark has been reported to possess hypoglycemic, diuretic, antidiarrheal, antiplasmodial and antitumor activities. 7, 8, 9. The active constituents of this plant are mostly
