2. Objective(s)

• Study about  the morphological characteristics and anatomical features of the plant Desmodium triquetrum.
• To isolate and identify the structure of chemical compounds from aerial parts of the plant Desmodium triquetrum.

3. Creativeness and innovativeness

• The first report about  the morphological characteristics and anatomical features of the plant Desmodium triquetrum.
• This is the first report on the presence of compound 4 in the plant D. triquetrum.

4. Research results

• Based on the morphological observations, we determined that the plant voucher specimen collected in Bac Kan, Vietnam, with vernacular names are known as “Mui mac”, “Co binh”, belongs to the species Desmodium triquetrum (L.) DC., a member of the family Fabaceae. The analytical phytotomy of leaves, stem, and root described herein also supports the conclusion. This is the first comprehensive morphological and anatomical study about this species.
• By chromatographic methods, 4 substances isolated from the plant and they were identified as kaempferol (1), astragalin (2), isoquercitrin (3), quercitrin (4) by analysis of physicochemical and spectroscopic data.
