Abstract:

This study was aimed to investigate the in vivo metabolism and accumulation of astaxanthin from Adonis
aestivalis in Artemia (brine shrimps). A total of 1400 48-h fasted adult brine shrimps were randomly divided into two groups
(700 brine shrimps per group): control and experimental groups. Shrimps were fed on dried powder of Adonis aestivalis
flower in experimental group and each group was extracted at 0.5, 1, 2, 3, 4 h and 5 h for C18-HPLC analysis. Results
showed that free astaxanthin started to accumulate in shrimps following feeding of Adonis aestivalis flower and reached the
maximum in 3 h. In addition, astaxanthin ethers in brine shrimps gradually disappeared. In conclusion, administration of
Adonis aestivalis flower powder to brine shrimps led to an increase in free astaxanthin. The astaxanthin eithers from Adonis
aestivalis flower were metabolically transformed into free astaxanthin and accumulated in vivo.
