“…The assay is based on the reduction of Mo(VI) to Mo(V) by analyte and the subsequent formation of a green phosphate/Mo(V) complex at an acidic pH (Pan et al, 2007a(Pan et al, , 2007bPrieto et al, 1999). The higher the absorbance, the stronger is the antioxidant activity.…”

Ultrasonically assisted extraction and Soxhlet extraction using 95% ethanol were performed to obtain ultrasonically assisted extract of Agrimonia pilosa (UEA) and Soxhlet extract of Agrimonia pilosa (SEA). The effects of the different extracting methods on the total phenolic (TP) and total flavonoid (TF) content of the extracts from Agrimonia pilosa were investigated. The findings showed that UEA contained higher TP and TF content than SEA. To understand better the effect of ultrasonic extraction, the antioxidant activities of UEA and SEA were evaluated with different antioxidant testing systems in vitro to determine reducing power, total antioxidant capacity, and free radical scavenging assays, including 2,2 0 -diphenyl-1-picrylhydrazyl (DPPH) and 2,2 0 -azinobis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radicals. Both SEA and UEA exhibited satisfied antioxidant activity superior to that of synthetic antioxidant butylated hydroxytoluene (BHT). The antioxidant activity of the tested subjects was in the order of UEA [ SEA [ BHT. Their high phenolic and flavonoid contents could be responsible for their antioxidant activity and pharmacologic actions.

The roots of three varieties of Polygonum cuspidatum were analyzed for resveratrol and its analogs. The powder of the dried roots was extracted with aqueous ethanol (60% v/v) and the extracts obtained were analyzed using RP HPLC with coulometric detection. A simple HPLC method with a multichannel CoulArray detector was developed for the determination of four stilbenes: resveratrol, its glucoside piceid, piceatannol, and its glucoside astringin. Analyses were carried out on a LiChrospher C18 (125 x 4.6 mm id, particle size 5 microm) column with a mobile phase of ammonium acetate (pH 3) and ACN in gradient mode. Four compounds were monitored by a CoulArray electrochemical detector. Potentials of eight electrochemical cells in series were set in the range of 200-900 mV. Optimization of the mobile phase pH was performed. Calibration curves showed good linearity with correlation coefficients (r(2))--more than 0.9975.
