Abstract

Background: Canavalia gladiata (Jacq.) DC. (Family Leguminosae) is a large annual or perennial climber with a terete glabrous stem, native to Indo-Malaysian and also distributed in tropical, subtropical regions. C. gladiata (Jacq.) DC. is generally confused with another closely related species i.e. C. ensiformis (Linn.) DC (Jack bean). The tender pods of both the above species have close similarity in morphology, especially shape and size of fruit, therefore it is difficult to differentiate on their vegetative and also fruiting stages. The plant C. ensiformis mentioned as a synonym of C. gladiata in many of the earlier literature though they are 2 different taxa. Some authors published different colour seeds in the name of C. gladiata . It is doubtful if C. ensiformis (Linn.) DC. or C. gladiata (Jacq.) DC was studied during that analysis. Objectives: A systematic pharmacognostical study has been executed to identify the correct botanical source. Materials and Methods: All the studies were carried out by standard procedures in Pharmacopoeias and other authentic literature. Results: Macroscopically surface characters followed by odour and taste, anatomically TS of the pericarp, plecenta, testa, cotyledon and radical, powder microscopically epidermal cells with stomata and prismatic crystal cystolith, trichomes, testa palisade cells, sclereids with different shape and size, brownish content, starch grains, tracheids, fibres and prismatic crystals of calcium oxalate are the unique diagnostic characters observed. HPTLC with different spots having unique Rf values in the pericarp, testa, cotyledon and seeds will be helpful for critical identification of the species. Conclusion: The findings of the present study will be helpful in the identification and differentiation of related species as the whole drug or in powder form.

背景:加拿大夏花(Jacq.)DC。(豆科)是一种大型一年生或多年生攀援植物,茎圆柱状无毛,原产于印度-马来西亚,也分布于热带和亚热带地区。C.gladiata(Jacq.)DC。通常与另一个亲缘关系密切的物种,即C.ensiformis(Linn.)DC(Jack bean)混淆。上述两种的嫩荚在形态上,特别是果实的形状和大小上有着密切的相似性,因此在营养期和结果期都很难区分。在许多早期文献中,C.ensiformis植物被称为C.gladiata的同义词,尽管它们是两个不同的分类群。一些作者以C.gladiata的名义发表了不同颜色的种子。ensiformis(Linn.)是否为DC是值得怀疑的。或C.gladiata(Jacq.)DC。目的:进行了一项系统的生药学研究,以确定正确的植物来源。材料和方法:所有研究均按照药典和其他权威文献中的标准程序进行。结果:从宏观上看,表面特征其次是气味和味道,从解剖学上看,果皮、软毛、种皮、子叶和根的TS,粉末显微镜下的表皮细胞有气孔和棱柱状晶体膀胱石,毛状体,种皮栅栏细胞,不同形状和大小的硬骨片,褐色含量,淀粉粒,管胞,草酸钙的纤维和棱柱状晶体是观察到的独特的诊断特征。在果皮、种皮、子叶和种子中具有独特Rf值的不同斑点的HPTLC将有助于物种的关键鉴定。结论:本研究的结果将有助于整个药物或粉末形式的相关物种的鉴定和分化。
