RESUMO
Objective To study the technique condition for separating and purifying total flavones from Striga asiatica (L.) O. Ktze. by Polyamide. Methods Total flavones content, in the sample solution of Striga asiatica (L.)O. Ktze. , detected by UV spectrophotometry, is used as the index. Some technological parameters are observed by single factor observation. Results Polyamide has good absorbing effect on total flavones of Striga asiatica (L.) O. Ktze. The liquid concentration of its absorbing and separating technological condition is 1.12～2. 24 mg/mL and at the absorbing speed of 2BV/h. The elution effect of 95 % alcohol of 250 mL is the best. Conclusion This method is simple and feasi-ble, fit for separating and purifying total falvones from Striga asiatica (L.) O. Ktze.
RESUMO
Objective To study the effects of epimedium koreanum flavones and davallia mariesil flavones on osteoporosis mice induced by retinoie acid.Methods The osteoporosis mice were induced by retinoic acid and then were fed with epimedium koreanum flavones and davallia mariesil flavones.The biochemical markers in serum were observed.Results The data showed that the blood AKP were higher in mice treated with two total flavones than mice in model group,the blood HOP/Cr,BGP,Ca2+ were lower in treated mice than model group(P＜0.01 or P＜0.05).Conclusion This study suggests that those two total flavones can effectively treat the osteoporosis mice induced by retinoic acid.
