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

Abstract

The goal of current study is to contribute the biochemical studies of five Astragalus (Astragalus anthlloides,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 ?-tocopherol content. Also, D3 vitamincontent of studied Astragalus species were found between 2,94±0,18 µg/g (Astragalus odaratus) and 12,53±,495µg/g (Astragalus anthlloides). On the other hand, ?-tocopherol content of Astragalus species have detectedbetween 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 studiedspecies. On the other hand, it was found that r-tocopherol, a-tocopherol acetate, D2, K1, retinol and retinol acetatecontents were lowest amounts or absent.
