| 摘要: |
| 目的 建立槟榔、焦槟榔、大腹皮中槟榔碱、槟榔次碱、去甲槟榔碱、去甲槟榔次碱含量的LC-PDA测定方法。方法 样品加氨水浸润，甲醇超声提取。ZORBAX 300-SCX色谱柱(150 mm×4.6 mm，5 μm)分离，流动相A为乙腈，流动相B为0.2%甲酸水(氨水调节pH=3.8)，梯度洗脱，流速为0.5 mL·min-1，柱温为30 ℃，进样量为5 μL，检测波长为225 nm。结果 槟榔碱、槟榔次碱、去甲槟榔碱、去甲槟榔次碱分别在2.98~745.0，2.60~650.0，1.19~595.0，1.22~610.0 μg·mL-1内与峰面积呈良好的线性关系(r2>0.999 0)。槟榔、焦槟榔、大腹皮中槟榔碱、槟榔次碱、去甲槟榔碱、去甲槟榔次碱的平均加样回收率(n=6)均在95.0%~105.0%，RSD<2.50%。槟榔和其炮制品中生物碱含量差异显著。结论 该方法快捷、灵敏、准确、可靠，可用于槟榔、焦槟榔、大腹皮中4种生物碱的含量测定，为槟榔及其饮片的质量控制提供了参考。 |

| Abstract: |
| OBJECTIVE To establish an LC-PDA method for determination of arecoline, arecaidine, guvacoline and guvacine in Arecae Semen, Arecae Semen Tostum and Arecae Pericarpium. METHODS The sample was soaked with ammonia, and extracted with methanol by ultrasonic extraction. The target compounds were separated on a ZORBAX 300-SCX column(150 mm×4.6 mm, 5 μm) with a gradient elution of acetonitrile(A)-0.2% acetic acid(B) solution(adjusted to pH=3.8 with ammonium) at the flow rate of 0.5 mL·min-1. The column temperature was 30 ℃, the injection volume was 5 μL, and the detection wavelength was set at 225 nm. RESULTS Arecoline, arecaidine, guvacoline and guvacine showed a good linear relationship with the peak area within 2.98-745.0, 2.60-650.0, 1.19-595.0, 1.22-610.0 μg·mL-1, respectively(r2>0.999 0). The average recoveries of arecoline, arecaidine, guvacoline and guvacine in Arecae Semen, Arecae Semen Tostum and Arecae Pericarpium were ranged from 95.0% to 105.0%, with RSD<2.50%(n=6). The content of alkaloids in Arecae Semen and its processed products was significantly different. CONCLUSION The proposed method is rapid, sensitive, accurate, reliable, which can be used for the determination of four alkaloids in Arecae Semen, Arecae Semen Tostum and Arecae Pericarpium. |
