ジンセノサイド類を含む生薬ニンジンの健康食品の品質評価

Abstract

We investigated by HPLC the contents of ginsenosides in overseas and Japanese ginseng health foods. The ginsenoside Rb1 was at the range of ND (not detected) ～ 43.3 mg/g, and the ginsenoside Rg1 was at the range of ND ～ 6.6 mg/g in 8 products of overseas ginseng health foods. In some health foods, ginsenosides contents were higher than that of the ginseng crude drug (Rb1 : 6.6 mg/g, Rg1 : 4.7 mg/g), and also varied between lots. The intake level of ginsenoside Rb1 + Rb1 from overseas health foods was estimated to be 0 ～ 96.9 mg/day. In some health foods, intake levels were higher than that of the ginseng conventional crude drug product (Rb1 + Rb1 : 16.2 mg/day). The ginsenoside Rb1 was at the range of 0.6 ～ 5.0 mg/g, and the ginsenoside Rg1 was at the range of 0.4 ～ 4.1 mg/g in 6 products of Japanese ginseng health foods. The intake level of ginsenoside Rb1 + Rb1 from Japanese health foods was estimated to be 0.6 ～ 35.7 mg/day, however one of them was higher than that of the ginseng conventional crude drug product.
