The Determination of Lipide- Soluble Vitamin Contents of Some Astragalus Taxa by Using HPLC

Abstract

Astragalus hirsutus, Astragalus campylorhynchus, Astragalus cephalotes var. cephalotes, Astragalus odaratus) species by determining the lipide-soluble vitamin contents based on HPLC analyse. Current study showed that A. anthlloides (208,95±4,09 µg/g) and A. hirsutus (200,9±2,8 µg/g) have high ϒ-tocopherol content. Also, D3 vitamin content of studied Astragalus species were found between 2,94±0,18 µg/g (Astragalus odaratus) and 12,53±,495 µg/g (Astragalus anthlloides). On the other hand, α-tocopherol content of Astragalus species have detected between 3,99±0,14 µg/g (Astragalus campylorhynchus) and 11,9±0,66 µg/g (Astragalus cephalotes var. cephalotes). However, it was found that A. hirsutus only have beta caroten content (3,55±0,43 µg/g) among studied species. On the other hand, it was found that r-tocopherol, a-tocopherol acetate, D2, K1, retinol and retinol acetate contents were lowest amounts or absent.
