- Abstract
- We report the efficiency of green subcritical water extraction (SWE) for the recovery of bioactive compounds from Allium hookeri root (AHR). The highest extraction yield (88 wt%) and highest contents of bioactive compounds including total phenolic content (29.4 mg of gallic acid equivalent/g of dry AHR), total flavonoid content (30.6 mg of quercetin equivalent/g of dry AHR), ascorbic acid (81 mg/g of dry AHR), and gallic acid (2.8 mg/g of dry AHR), as well as high concentrations of Maillard reaction products (melanoidins), and various rare sugars were achieved at 160 degrees C for 30 min. The SWE extracts possessed 89.3-91.8 % higher antioxidant activities than those of the Soxhlet water extract. As a result, the SWE extract showed strong anticancer effects against human cancer cells of the HT-1080 (fibrosarcoma) and MDA-MB-231 (breast cancer) cell lines, suggesting the possible application of the AHR extract obtained via SWE in cancer therapy and prevention.
