        摘   要   目的:分析并比较不同生长年限黄芪中 6 种单糖的含量。方法:取来自 3 个产地的 2~4 年生黄芪药材,经水提醇沉、
        Sevage除蛋白后制得黄芪多糖;将上述多糖经三氟乙酸水解和1-苯基-3-甲基-5-吡唑啉酮衍生化后,采用高效液相色谱法测定其
        中甘露糖、鼠李糖、半乳糖醛酸、葡萄糖、半乳糖、阿拉伯糖等 6 种单糖的含量。以 Symmetry C18为色谱柱,以磷酸盐缓冲液(pH
        6.8)-乙腈(84 ∶ 16,V/V)为流动相,流速为1.0 mL/min,检测波长为245 nm,柱温为35 ℃,进样量为20 µL。结果:黄芪多糖中甘露
        糖、鼠李糖、半乳糖醛酸、葡萄糖、半乳糖、阿拉伯糖的含量分别为 0.50~0.94、0.76~1.60、3.35~7.86、87.33~275.77、1.95~8.96、
        2.35~14.04 mg/g,2、3、4年生黄芪中上述单糖的总含量分别为98.26~139.92、173.81~295.71、122.37~182.41 mg/g。3年生黄芪
        中葡萄糖的含量与2、4年生黄芪有显著差异(162.71~275.77 mg/g vs. 87.33~107.70、111.54~167.26 mg/g,P<0.05)。结论:2、3、
        4年生黄芪中均检出上述6种单糖,其中葡萄糖含量最高,且3年生黄芪中葡萄糖含量显著高于2、4年生黄芪。

        ABSTRACT    OBJECTIVE:To analyze and compare the contents of 6 kinds of monosaccharide in Astragalus membranaceus from
        different growth years. METHODS:2-4 years old A. membranaceus from three areas were extracted with water extraction and
        alcohol precipitation,Sevage deproteinization to obtain A. membranaceus polysaccharide. The samples were firstly hydrolyzed with
        trifluoroacetic acid(TFA)and then derivatized by 1-phenyl-3-methyl-5-pyrazolone(PMP). HPLC analysis was adopted to determine
        the contents of 6 kinds of monosaccharide as mannose, rhamnose, galacturonic acid, glucose, galactose, arabinose. The
