摘要: 建立了高效液相色谱测定罗汉果中罗汉果苷Ⅴ、罗汉果苷ⅣA、罗汉果苷Ⅲ、11-氧化罗汉果苷Ⅲ、罗汉果苷ⅡE和11-氧化罗汉果苷ⅡE等6种苷类化合物含量的方法。采用的色谱条件:ZORBAX SB-C18色谱柱(150 mm×4.6 mm, 5 μm);柱温30 ℃;以水(A相)和乙腈(B相)为流动相,梯度洗脱程序:0~3 min,20%B~30%B;3~8 min,30%B~35%B;8~9 min,35%B;流速0.8 mL/min;检测波长203 nm;进样量10 μL。结果表明,以上6种苷类化合物分别在0.04~1.0 mg/mL、0.011~0.68 mg/mL、0.010~0.80 mg/mL、0.0097~0.58 mg/mL、0.025~1.0 mg/mL、0.013~0.76 mg/mL范围内线性关系良好(r>0.9991)。加标回收率依次为99.65%,101.6%,97.05%,103.1%,99.25%和103.0%;相对标准偏差分别为0.83%,3.1%,1.9%,3.3%,0.59%和2.0%。该方法简便、快速、准确,适用于罗汉果原材料及其制品中苷类化合物的检测和含量测定。

Abstract: Siraitia grosvenorii, a traditional Chinese fruit, belongs to the family Cucurbitaceae and has been used as a pulmonary demulcent and emollient for the treatment of dry cough, sore throat, dire thirst, and constipation in folk medicine. A high performance liquid chromatographic method was developed for simultaneous determining the contents of mogrosideⅤ, mogrosideⅣA, mogrosideⅢ, 11-oxomogrosideⅢ, mogrosideⅡE and 11-oxomogrosideⅡE in Siraitia grosvenorii fruits. The chromatographic analysis was carried out on a ZORBAX SB-C18 column (150 mm×4.6 mm, 5 μm). The mobile phase was water (A) and acetonitrile (B) with gradient elution (0-3 min, 20%B-30%B; 3-8 min, 30%B-35%B; 8-9 min, 35%B). The flow rate was maintained at 0.8 mL/min. The detection wavelength was set at 203 nm and the column temperature was controlled at 30 ℃. The sample injection volume was 10 μL. The calibration curves were linear over the ranges of 0.04-1.0 mg/mL, 0.011-0.68 mg/mL, 0.010-0.80 mg/mL, 0.0097-0.58 mg/mL, 0.025-1.0 mg/mL and 0.013-0.76 mg/mL (r>0.9991) for the above cucurbitane triterpene glycosides, respectively. The average recoveries were 99.65% for mogrosideⅤ, 101.6% for mogroside ⅣA, 97.05% for mogroside Ⅲ, 103.1% for 11-oxomogrosideⅢ, 99.25% for mogrosideⅡE, and 103.0% for 11-oxomogrosideⅡE, with the relative standard deviations of 0.83%, 3.1%, 1.9%, 3.3%, 0.59% and 2.0%, respectively. This simple, rapid and accurate method is suitable for quality control and determination of raw materials and products of Siraitia grosvenorii fruits.
