【摘要】：姜具有豐富的食品價(jià)值和藥用保健功效,姜皮中含有豐富的生物活性成分,具有廣闊的開發(fā)前景。研究應(yīng)用二極管陣列高效液相色譜法對(duì)姜皮中姜辣素物質(zhì)進(jìn)行了分析,色譜條件為:Syncronis C_(18)柱,流動(dòng)相是乙腈和0.1%甲酸水為流動(dòng)相,采用梯度洗脫,流速1.0 m L/min,柱溫為30℃,檢測波長280 nm。在0~200 mg/L范圍內(nèi)五種姜辣素類物質(zhì)均具有良好的線性關(guān)系。精密度RSD值在0.02%~1.24%之間。加標(biāo)回收率在95.45%~99.52%之間,最低檢出限在0.014~0.091μg/m L之間。該法快速,簡便,靈敏,準(zhǔn)確,重現(xiàn)性好,可有效地用于姜皮中姜辣素類物質(zhì)含量的測定。
[Abstract]:Ginger has abundant food value and medicinal health care function, and the ginger peel contains rich bioactive ingredients. Diode array high performance liquid chromatography (HPLC) was used to analyze gingerol in curcuma peel. The chromatographic conditions were as follows: 1 Syncronis Che 18) column. The mobile phase was acetonitrile and 0.1% formic acid water as mobile phase, gradient elution was used, flow rate was 1.0 mL / min, column temperature was 30 鈩，
