Abstract
Panax ginseng CA Meyer has a variety of biological effects, including antioxidant and antidiabetic activities. Ginseng requires long-term cultivation, but this can be shortened using hydroponic systems to facilitate the commercial development of ginseng as a functional food. However, the characteristics of short-term-cultured (< 30 days) hydroponic ginseng (sHCG) are unclear. We investigated the characteristics of 21-day-cultured sHCG compared 5-year-old normally cultured ginseng. The free radical-scavenging activity and total ginsenoside and phenolic contents were significantly higher in sHCG than in normally cultured ginseng. Fifteen ginsenosides were detected in sHCG, and the concentrations of most were higher in shoots than roots. These findings suggest that 21-day-cultured sHCG, due to its enhanced antioxidant activity and higher concentrations of total phenolics and ginsenosides (including Rd and Re), has potential as a functional food.

Summary
Panax ginseng CA Meyer (Korean ginseng) is a perennial plant of the family Araliaceae and has been used as an ingredient in traditional herbal medicines for over 2,000 years, in Asia. Most of which belong to one of two major functional types: protopanaxadiol (PPD) and protopanaxatriol (PPT) types As these two types of ginsenoside exert different physiological effects (Chen et al, 2016), the PPD/PPT ratio is calculated to determine the bioactivity of ginseng (Shan et al, 2014). After transplantation of 2-year-old ginseng into a hydroponic system, the ginsenoside content of leaves steadily increased from 7 to 56 days, whereas that in roots increased until 21 days and steeply declined thereafter. The optimal cultivation duration for 2-year-old ginseng seedlings after transplantation in hydroponic systems may be less than 30 days (Jang et al, 2018). We evaluated the antioxidant activity, total ginsenoside content, phenolic content and profiles of 22 ginsenosides in 21-day hydroponically cultured ginseng (sHCG) compared with 5-year-old normally cultured ginseng
