Abstract:
NaNO2-Al(NO3)3-NaOH spectrophotometry and orthogonal experiment was used to optimize the extraction process of flavonoids in Anoectochilus.Through single factor test and orthogonal test,effect of ethanol concentration,solid-liquid ratio,extraction temperature and extraction time on the extraction effect of flavonoids compounds from Anoectochilus were investigated.The results showed that the influence of Anoectochilus flavonoids compoundsextraction yield of the size of the order for ethanol concentration>extraction temperature>extraction time>solid-liquid ratio.Best process conditions for the extraction of flavonoids compoundsin Anoectochilus,ethanol concentration of 95%,material-liquidratio of 1∶40 g?mL-1,extraction temperature of 70 ℃,extracting time of 60 minutes.Under this condition,the extract flavonoids compoundsyield in Anoectochilus were 25.426 mg?mL-1.This research could provide theoretical basis and reference data for the industrial production of Anoectochilus.
