目的 测定牵牛子脂肪油中的棕榈酸、硬脂酸、油酸、亚油酸和亚麻酸.方法 采用毛细管气相色谱法,对被测成分甲酯化后测定.色谱柱为DB-Wax毛细管柱(30 m×0.25 mm,0.25 μm);检测器为FID;程序升温,起始温度170℃,以10℃/min升至230℃后,保持5 min;分流比15∶1.结果 棕榈酸、硬脂酸、油酸、亚油酸和亚麻酸质量浓度分别在0.04~0.57 mg/mL(r=0.999 6),0.01~0.18 mg/mL(r=0.999 6),0.02~0.35 mg/mL(r=0.999 8),0.05~0.82 mg/mL(r=0.999 7),0.004 ~0.06 mg/mL(r =0.9994)范围内,与峰面积呈良好的线性关系;平均回收率(n=9)分别为98.5%,96.4%,97.2%,98.2%,95.7%.结论 本法简便、准确,重复性好,可用于牵牛子脂肪油的质量控制.
目的 測定牽牛子脂肪油中的棕櫚痠、硬脂痠、油痠、亞油痠和亞痳痠.方法 採用毛細管氣相色譜法,對被測成分甲酯化後測定.色譜柱為DB-Wax毛細管柱(30 m×0.25 mm,0.25 μm);檢測器為FID;程序升溫,起始溫度170℃,以10℃/min升至230℃後,保持5 min;分流比15∶1.結果 棕櫚痠、硬脂痠、油痠、亞油痠和亞痳痠質量濃度分彆在0.04~0.57 mg/mL(r=0.999 6),0.01~0.18 mg/mL(r=0.999 6),0.02~0.35 mg/mL(r=0.999 8),0.05~0.82 mg/mL(r=0.999 7),0.004 ~0.06 mg/mL(r =0.9994)範圍內,與峰麵積呈良好的線性關繫;平均迴收率(n=9)分彆為98.5%,96.4%,97.2%,98.2%,95.7%.結論 本法簡便、準確,重複性好,可用于牽牛子脂肪油的質量控製.
