Rosmarinic acid is a naturally antioxidant, which is biosynthesized from the amino acids Lphenylalanine and L-tyrosine by eight enzymes that include phenylalanine ammonia lyase and cinnamic acid 4-hydroxylase. Rosmarinic acid can also be chemically produced by the esterification of caffeic acid and 3,4-dihydroxyphenyllactic acid. Recently, rosmarinic acid and its derivatives (RA) have attracted interests for their biological activities, which include antiinflammatory, anti-oxidant, anti-angiogenic, anti-tumor, and anti-microbial functions. RA extraction procedure from Xaden leaves Celastrus hindsii was investigated. RA extracts were obtained from 50 % ethanol extract. The optimal conditions for extraction were as followings: solvent/material ratio 12/1 (v/m), two time extractions, and total extraction time of 3 hours. RA extracts were refined by Diaion HP-20column to have RA with 83.30 % purity and yield 2.86 % (by dry weight material).
