Abstract
|
|
|
|
In this study, hydroponically-cultivated ginseng leaves, fruits, and roots were respectively extracted with ethanol. The contents of 12 ginsenosides and three phenolics in the extracts were quantitatively analyzed and the free radical scavenging activities were measured and compared. Hydroponically-cultivated ginseng leaves contained higher levels of gensenosides (Rg1, Rg2+Rh1, Rd, and Rg3) and p-coumaric acid than the other parts of the ginseng plants. The 2,2'-azino-di-(3-ethylbenzothiazoline)-6-sulfonic acid radical scavenging activities of leaves were also the highest. Accordingly, hydroponically-grown ginseng leaves were shown to hold promise for use as an environmentally-friendly natural anti-oxidant.
