TITLE:
摘要: 目的:建立同时测定桂枝汤中9种主要成分含量的方法,比较传统煎煮和煎药机煎煮对桂枝汤中上述成分含量的影响。方法:采用高效液相色谱法。色谱柱为Agilent Zorbax SB C18,流动相为乙腈-0.1%磷酸(梯度洗脱),流速为1.0 ml/min,检测波长为230 nm(芍药内酯苷、芍药苷、甘草苷)、254 nm(桂皮醛、甘草酸)、280 nm(没食子酸、香豆素、桂皮酸、2-甲氧基桂皮醛),柱温为25 ℃,进样量为10 μl。结果:没食子酸、芍药内酯苷、芍药苷、甘草苷、香豆素、桂皮酸、桂皮醛、2-甲氧基桂皮醛和甘草酸检测质量浓度线性范围分别为0.410 2~210.0(r=0.999 9)、0.994 0~254.5(r=0.999 9)、1.636 0~1 675.0(r=0.999 9)、0.988 3~506.0(r=0.999 6)、0.987 3~31.59(r=0.999 5)、0.486 8~124.6(r=0.999 5)、2.458 0~314.6(r=0.999 5)、0.034 3~1.096(r=0.999 8)、1.711 0~219.0 μg/ml(r=0.999 7);精密度、稳定性、重复性试验的RSD<5%,加样回收率分别为93.56%~103.19%(RSD=4.00%,n=9)、101.51%~107.32%(RSD=2.21%,n=9)、95.08%~103.76%(RSD=2.87%,n=9)、100.82%~105.73%(RSD=1.85%,n=9)、85.08%~89.12%(RSD=1.40%,n=9)、92.31%~99.12%(RSD=2.71%,n=9)、99.17%~102.32%(RSD=1.24%,n=9)、100.15%~103.98%(RSD=1.18%,n=9)、99.93%~102.61%(RSD=1.03%,n=9)。煎药机煎煮所得总有效成分含量为4 565 μg/g,传统煎煮所得总有效成分含量为2 742 μg/g。结论:该方法操作简便、稳定、重复性好,可用于桂枝汤中9种主要成分含量的同时测定,其中没食子酸、芍药内酯苷和2-甲氧基桂皮醛的含量测定为桂枝汤中首次报道。煎药机煎煮所得总有效成分含量高于传统煎煮所得总有效成分。
ABSTRACT: OBJECTIVE:To establish a method for the contents determination of 9 components in Guizhi decoction, and compare the effects of traditional decoction method and the extracting machine decoction method on these contents in Guizhi decoction. METHODS: HPLC was performed on the column of Agilent Zorbax SB-C18 with mobile phaseof acetonitrile - 0.1% phosphoric acid (gradient elution) at a flow rate of 1.0 ml/min, the detection wavelength was 230 nm, 254 nm and 280 nm, the column temperature was 25 ℃, and the injection volume was 10 μl. RESULTS: The linear range was 0.410 2-210.0 μg/ml for gallic acid(r=0.999 9),0.994 0-254.5 μg/ml for albiflorin(r=0.999 9),1.636 0-1 675.0 μg/ml for paeoniflorin(r=0.999 9),0.988 3-506.0 μg/ml for liquiritin(r=0.999 6),0.987 3-31.59 μg/ml for coumarin(r=0.999 5),0.486 8-124.6 μg/ml for cinnamic acid(r=0.999 5),2.458 0-314.6 μg/ml for cinnamaldehyde(r=0.999 5),0.034 3-1.096 μg/ml for 2-methoxy cinnamaldehyde(r=0.999 8),and 1.711 0-219.0 μg/ml for glycyrrdhizic acid (r=0.999 7); RSDs of precision, stability and reproducibility tests were lower than 5%, recoveries were 93.56%-103.19%(RSD=4.00%,n=9)、101.51%-107.32%(RSD=2.21%,n=9)、95.08%-103.76%(RSD=2.87%,n=9)、100.82%-105.73%(RSD=1.85%,n=9)、85.08%-89.12%(RSD=1.40%,n=9)、92.31%-99.12%(RSD=2.71%,n=9)、99.17%-102.32%(RSD=1.24%,n=9)、100.15%-103.98%(RSD=1.18%,n=9)、99.93%-102.61%(RSD=1.03%,n=9). The content of total effective components from the extracting machine decoction method was 4 565 μg/g, that from the traditional decoction method was 2 742 μg/g.CONCLUSIONS:The method is simple, stable and reproducible, and can be used for the simultaneous determination of 9 componentsin Guizhi decoction. The contents of gallic acid,albiflorin and 2-methoxy cinnamaldehyde are first reported. The total effective components from the extracting machine decoction method are higher than that from the traditional decoction method.
