| 摘要: |
| 目的 采用UV和HPLC法比较野生与种植黄连植株不同部位生物碱含量差异。方法 UV法在波长345 nm处测定黄连总生物碱含量，HPLC采用C18（4.6 mm×250 mm，5 μm）色谱柱，乙腈和0.4%磷酸水溶液（25：75）等度洗脱，流速1.0 mL/min，进样量10 μL，检测波长345 nm，柱温30℃以测定盐酸小檗碱含量。结果 黄连不同部位的总生物碱含量：种植黄连根茎含（9.88±0.03）%、须根含（6.41±0.03）%、茎叶含（1.92±0.04）%；野生黄连根茎含（7.95±0.03）%、茎叶含（0.64±0.03）%。黄连不同部位的的盐酸小檗碱含量：种植黄连根茎含（0.45±0.04）%、须根含（0.17±0.03）%、茎叶含（0.09±0.03）%；野生黄连根茎含（0.38±0.03）%、茎叶含（0.16±0.03）%。结论 种植黄连植株不同部位的总生物碱含量高于野生黄连，但其盐酸小檗碱含量低于野生黄连植株；野生与种植黄连均为根茎部总生物碱和盐酸小檗碱含量最高。 |

| Abstract: |
| Objective To compare the alkaloid content in different parts of wild and cultivated Coptis chinensis by UV and HPLC. Methods Determination of total alkaloids in Coptis chinensis by ultraviolet spectrophotometry at 345 nm. HPLC was performed on C18(4.6 mm×250 mm, 5 μm) chromatographic column by isocratic elution with acetonitrile -0.4% phosphoric acid aqueous (25:75) as mobile phase, the flow rate was 1 mL/min, the injection volume was 10 μL, the detection wave length was 345 nm, the column temperature was set at 30℃. Results The content of total alkaloids in cultivated Coptis chinensis:the rhizome, fibrous root, cauline contains (9.88±0.03)%, (6.41±0.03)%, (1.92±0.04)%, respectively; The content of total alkaloids in wild Coptis chinensis:rhizome was (7.95±0.03)%, stem and leaf was (0.64±0.03)%. The content of berberine hydrochloride in cultivated Coptis chinensis:rhizome was (0.45±0.04)%, fibrous root, and stem and leaf contain (0.17±0.03)%, (0.09±0.03)%, respectively. The content of berberine hydrochloride in wild Coptis chinensis:rhizome was (0.38±0.03)%, and that of stem and leaf was (0.16±0.03)%. Conclusion The content of total alkaloids in different parts of cultivated Coptis chinensis was higher than that in wild Coptis chinensis, but the content of berberine hydrochloride was lower than that in wild Coptis chinensis. The rhizome part in both wild and cultivated Coptis chinensis had the highest content of total alkaloids and berberine hydrochloride. |
