Nghiên cứu đặc điểm thực vật và định tính một số nhóm chất của loài Cỏ đuôi lươn (Desmodium rubrum (Lour.) DC.) thu hái tại xã Bất Bạt, Hà Nội

Abstract

Objective: To build a data set on the morphological and microscopic features and determine the chemical constituents of Desmodium rubrum (Lour.) DC collected in Bat Bat Commune, Ha Noi.

Subjects and methods: Desmodium rubrum (Lour.) DC. plants from Bat Bat commune, Ha Noi city were analyzed for morphological and anatomical features, with photographic documentation of the powdered material. The scientific name was identified by morphological comparison. A preliminary phytochemical screening was conducted using standard chemical reactions and thin-layer chromatography (TLC).

Results: The botanical characteristics of the plant were described, confirming the specimen's identity as Desmodium rubrum (Lour.) DC. Eleven groups of compounds were detected, including flavonoids, tannins, saponins, coumarins, cardiac glycosides, reducing sugars, lipids, organic acids, carotenoids, sterols, and polysaccharides. The solvent system composed of ethyl acetate: formic acid: H₂O (8:1:1) provided good separation on the chromatogram.

Conclusion: The morphological and anatomical features of Co duoi luon were described and illustrated in detail, providing a basis for species identification. 11 groups of organic compounds were detected, and thin-layer chromatography was employed to evaluate the separation of the extract using ethyl acetate: formic acid: water (8:1:1) as the mobile phase.
