Antioxidant capacity of anthocyanins from Rhodomyrtus tomentosa (Ait.) and identification of the major anthocyanins
The anthocyanins in the fruits of Rhodomyrtus tomentosa (ACN) were extracted by 1% TFA
in methanol, and then purified by X-5 resin column and C18 (SPE) cartridges. The purified
anthocyanin extract (ART) from the fruits of R. tomentosa showed strong antioxidant
activities, including DPPH radical-scavenging capacity, ABTS radical scavenging capacity,
reducing power and oxygen radical absorbance capacity (ORAC). The purified anthocyanin
extract was analyzed by high performance liquid chromatography (HPLC). The major …
