Tóm tắt

The objective of this study is to evaluate the growth and functional components of ginseng sprouts
aeroponically grown in Vietnam. One-year-old ginseng roots were used in a controlled-environmental
aeroponic system including, temperature, humidity, light, pH, and EC. The growth characteristics of ginseng
sprouts consisting of plant height, stem length, plant weight, and stem diameter were measured after 30 days
of transplanting. Furthermore, functional components (total saponin, total polysaccharide, and total
flavonoid) in root, leaf and stem were also extracted. Results showed that the plant height and stem length of
ginseng sprouts grown in Vietnam were higher than those grown in South Korea. The content of saponin
and flavonoid in the leaf and stem was higher than that in the root, whereas the content of polysaccharides
in the leaf and stem was lower than that in the root. Additionally, the content of ginsenosides (e.g. Rg1, Re,
Rf, Rb1) in ginseng sprouts grown in Vietnam was lower than those grown in South Korea in both
traditional farming and aeroponical methods.
