| 摘要: |
| 目的 建立显齿蛇葡萄茎中黄酮类成分的含量测定方法，分析广西不同地区显齿蛇葡萄茎中二氢杨梅素、芦丁及杨梅素的含量。方法 采用色谱柱为PoroshellEC-C18（4.6 mm×250 mm，4.0 μm），以乙腈-0.1%磷酸为流动相，梯度洗脱，流速1 mL·min-1，柱温25℃，检测波长0~23 min，330 nm；23~50 min，375 nm。结果 显齿蛇葡萄茎中二氢杨梅素、芦丁及杨梅素进样量分别在0.800 5~9.606 μg（r=0.999 9）、0.201 6~2.419 μg（r=0.999 8）和0.100~1.202 μg（r=0.999 7）内呈良好的线性关系；平均加样回收率分别为98.1%，101%和99.9%，RSD<3%，方法的稳定性、重复性和精密度均良好（RSD<3%）。桂林灵川的显齿蛇葡萄茎中二氢杨梅素、芦丁和杨梅素的含量均较高，武鸣双江和金秀互助村的显齿蛇葡萄茎中二氢杨梅素和杨梅素含量均较低，而武鸣双江的芦丁含量较高，柳州泗顶镇的芦丁含量较低。结论 不同地区显齿蛇葡萄茎中二氢杨梅素、芦丁和杨梅素的含量相差较大。该方法结果准确、重复性好，可使目标成分与试样中其他共存组分达到较好地分离。 |

| Abstract: |
| OBJECTIVE To establish a method for the determination of contents of flavonoids and analyze the contents of dihydromyricetin, rutin and myricetin in Ampelopsis grossedentata stems from different areas of Guangxi. METHODS HPLC method was adopted. The separation was performed on Agilent PoroshellEC-C18(4.6 mm×250 mm, 4.0 μm) column and the mobile phase consisted of acetonitrile and 0.1% H3PO4 water solution in gradient elution at flow rate of 1 mL·min-1, the column temperature was 25, the detection wavelengths were set at 330℃ nm for dihydromyricetin and 375 nm for myricetin. RESULTS The linear ranges were 0.800 5-9.606 μg(r=0.999 9) for dihydromyricetin, 0.201 6-2.419 2 μg(r=0.999 8) for rutin and 0.100-1.202 μg(r=0.999 7) for myricetin, and the average recovery were 98.1%, 101% and 99.9%, respectively, RSDs<3%. The determined results showed that the contents of dihydromyricetin, rutin and myricetin in Ampelopsis grossedentata stems from Lingchuan of Guilin were higher, and the contents in dihydromyricetin and myricetin in Ampelopsis grossedentata stems from Shuangjiang of Wuming and Huzhu Cun of Jinxiu were lower; the contents of rutin in Ampelopsis grossedentata stems from Shuangjiang of Wuming were higher, and the contents of rutin from Siding Zhen of Liuzhou were lower. CONCLUSION The contents of dihydromyricetin, rutin and myricetin in Ampelopsis grossedentata stems from different areas were quite different. This method can be better to separate from coexisting component, with good separation, and the results showed the method had high accuracy and good reproducibility. |
