چکیده
|
Beta-carotene is an important functional ingredient in human food supply,which needed to be quantified exactly. in presented study,pure β-carotene was used to evaluate four methods for the quantitative determination of β-carotene. the four methods included uv spectrophotometric determination,extraction-uv spectrophotometric determination,hplc(high performance liquid chromatography) separation and extraction-hplc separation with c18 column. the results confirmed that all of these methods were sufficient for β-carotene quantification. the extraction with hexane/ethanol proved the recovery of hplc separation,especially when the concentration of β-carotene was high. © 2016,chemical society of pakistan. all rights reserved.
