【 摘 要 】

Mucuna pruriens is a plant of Fabaceae family. Seed of M. pruriens is considered as a rich source of levo-3,4 dihydroxyphenylalanine (L-DOPA), a non-protein phenolic amino acid. In the present study, three different extraction methods were compared for extract yield, concentration of bioactive compounds such as total phenol, L-DOPA and antioxidant capacity. Extracts were prepared using water acidified with hydrochloric acid (0.1 N) by conventional method of refluxing as well as two green methods namely ultrasound and microwave assisted solvent extraction. A rapid and qualified high-performance liquid chromatography method was also developed for quantification of L-DOPA in different extracts. Among the three extraction methods, microwave assisted extraction provided the best results for yield and quality of M. pruriens extract in much shorter time in comparison to refluxing method of extraction.
