杏果肉%β-胡萝卜素%高效液相色谱法
杏果肉%β-鬍蘿蔔素%高效液相色譜法
행과육%β-호라복소%고효액상색보법
apricot pulp%β-carotene%HPLC
采用高效液相色谱法测定了18种杏果肉中β-胡萝卜素的含量。样品采用丙酮∶石油醚（体积比20∶80）提取，40℃水浴旋转蒸发至干，无水乙醇定容，高效液相色谱测定。检测波长450 nm，定量检测限0.1 mg/kg，方法快速有效，线性关系良好。经检测表明，杏果肉中含有丰富的β-胡萝卜素，其中以骆驼黄杏的β-胡萝卜素含量最高为（17.55±0.27） mg/kg。
採用高效液相色譜法測定瞭18種杏果肉中β-鬍蘿蔔素的含量。樣品採用丙酮∶石油醚（體積比20∶80）提取，40℃水浴鏇轉蒸髮至榦，無水乙醇定容，高效液相色譜測定。檢測波長450 nm，定量檢測限0.1 mg/kg，方法快速有效，線性關繫良好。經檢測錶明，杏果肉中含有豐富的β-鬍蘿蔔素，其中以駱駝黃杏的β-鬍蘿蔔素含量最高為（17.55±0.27） mg/kg。
채용고효액상색보법측정료18충행과육중β-호라복소적함량。양품채용병동∶석유미（체적비20∶80）제취，40℃수욕선전증발지간，무수을순정용，고효액상색보측정。검측파장450 nm，정량검측한0.1 mg/kg，방법쾌속유효，선성관계량호。경검측표명，행과육중함유봉부적β-호라복소，기중이락타황행적β-호라복소함량최고위（17.55±0.27） mg/kg。
Measured β-carotene content in 18 kinds of apricot pulp by HPLC (high performance liquid chromatography). Samples extracted with acetone∶petroleum ether (20∶80), rotary evaporated to dryness in 40℃water bath, diluted with ethanol, and detected with HPLC. Detection wavelength is 450 nm, quantitative detection limit is 0.1mg/kg. This method has characteristics of fast and effective , exact linear relation. The test showed that, apricot pulp was rich in β-carotene, the highest content of β-carotene in all of varieties is Luotuohuang apricot which is up to (17.55±0.27) mg/kg.
