What Is PERSEA GRATISSIMA (AVOCADO) OIL UNSAPONIFIABLES?
Persea Gratissima (Avocado) Oil Unsaponifiables (牛油果不皂化物, ASU, CAS 91770-40-0) 是牛油果油中不能被皂化的脂质精华部分，富含植物甾醇 (phytosterols, ~50%)、角鲨烯 (squalene)、维生素 E 和三萜醇 (triterpene alcohols)。ASU 是牛油果油中最具生物活性的组分，具有显著的促胶原合成 (collagen synthesis) 和抗炎特性 (anti-inflammatory)。临床研究表明 ASU 可增加皮肤胶原密度并减少紫外线引起的炎症。
