Floratheasaponin A-C is known to significantly reduce the amount of neutral lipids (triglycerides) in blood serum for 50-100 mg/kg[1]. For this activity, acylation at 21 and 22 positions of the triterpene structure is necessary. Chakasaponin I-III inhibits pancreatic lipase and for this activity, the hydroxyl group at position 15 is important. Other functionality of floral saponins are anti-allergy and gastric mucosal protection [2]. |
Floratheasaponin A-C は50-100 mg/kg の用量なら、血中の中性脂質(トリグリセリド)を有意に抑制します。 この活性には、トリテルペン部の21,22位に結合したアシル基が必須です。 またchakasaponin I-IIIは膵リパーゼ阻害作用を持ち、これには15位水酸基の存在が重要です。 その他、抗アレルギー、胃粘膜保護作用等も見出されています。 |
