Background: This study was carried out to determine the best time for collecting ginseng berries without reducing the ginsenoside- Re 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.
