Abstract

Alkaloid content and its components type of the species Cuscuta chinensis wasdetermined by using high-performance liquid chromatography (HPLC). The effectiveness of the aqueous extract of the studied species at concentration of 100 mg /ml was evaluated on the growth of four species of pathogenic bacteria positive and negative gram (Staphylococcus aurens, Escherichia coli, Pseudomonas aeruginosa and Kocuria rosea). The anti-oxidant effectiveness of the C. chinensis was studied by 2,2-Diphenyl-1-picrylhydrazyl (DPPH). Six alkaloids (Isolupanine, Retmine, Cuscutine, Isoquinoline, Aloperine and Lupanine) were diagnosed and the aqueous extract showed its effective on growth inhibition of the studied species of bacteria. The inhibition proportion reached to 92.49% as compared to the standard ascorbic acid (94.09%).
