Abstract

Background: This study was carried out to determine the best time for collecting ginseng berries without reducing the ginsenosideRe content of ginseng roots, which are used as food, medicine, or cosmetic materials.
Methods and Results: The test variety of ginseng used in this study was is Chunpung, which was collected from a 4-year-old ginseng field. Ginseng berries were collected at 7, 14, 21, 28, 35, 42, 49, and 56 days after flowering. The number of berry bunches per 1.62 ㎡ ranged from 43.4 to 61.4, while the weight of berries per 1.62 ㎡ was the greatest when they were collected 49 days after flowering. The root fresh weight per 1.62 ㎡ was increased by 0.21 - 1.00 ㎏ compared with that before the test, but root weight gain was decreased as the berry collection time was delayed. Total ginsenoside content of 4-year-old ginseng was the highest when berries were collected 7 days after flowering, while the ginsenoside-Re contents was the highest when collection was done 14 days after flowering.
Conclusions: The most suitable period for ginseng berry collection was proposed to be from 14 to 21 days after flowering, as this is when the content of ginsenoside-Re, which is useful as a medicinal or cosmetic material, is still high and the ginseng root has not yet decreased in weight.
