摘要

木蔷薇(Desr.)Kostel同义词Diospyros peregrina Gurke(科:Ebenaceae)是一种中等大小的常绿树木,通常在阿萨姆邦被称为Kendu。这种植物具有民族医学意义,被印度东北部的各个民族社区用来治疗各种疾病,如痢疾、糖尿病、腹泻、疟疾、溃疡和伤口。然而,没有详细的科学资料来鉴定这种植物材料,以确定其质量和纯度。因此,本文对马拉巴利木茎皮进行了形态解剖和理化分析。树皮外观为深褐色至黑色,粗糙,有气味和涩味。树皮显微镜下可见多角形厚壁软木、3-4层状木栓、7-8层状木栓层、石细胞、韧皮部纤维和髓质射线。茎皮粉具有厚壁软木细胞、厚壁细长韧皮部纤维、木质化石细胞和草酸钙菱形晶体。理化分析表明,干燥损失、总灰分损失、水溶性灰分损失和酸不溶性灰分损失分别为6.2、5.6、1.1、2.45和5.7% w/w。茎皮的醇溶物和水溶性浸出物含量分别为10.6和16.8% w/w。初步植物化学筛选结果表明,其中含有三萜、皂苷、单宁、黄酮类化合物和甾醇。本研究的结果将促进植物材料的生药学标准化,并有助于编制该物种的草药专著。

Morpho-Anatomical and Physicochemical Standardization of Diospyros malabarica (Desr.) Kostel Stem Bark
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.
