| TITLE： | Comprehensive evaluation of the quality of Amomum tsao -ko based on entropy weight TOPSIS method |
| 摘要： | 目的 综合评价不同产地、采收期草果的质量。方法使用2020年版《中国药典》（四部）中挥发油测定甲法测定草果中总挥发油含量；采用硝酸铝-亚硝酸钠比色法和福林酚法分别测定草果中总黄酮、总多酚含量；采用气相色谱法测定草果挥发油中α-蒎烯、β-蒎烯、1，8-桉叶素、α-松油醇、香叶醇、反式橙花叔醇含量；采用超高效液相色谱法测定草果中原儿茶酸、香草酸含量。选择上述11个指标，结合熵权TOPSIS法综合评价16批草果的质量。结果16批草果样品中总挥发油、总黄酮、总多酚、α-蒎烯、β-蒎烯、1，8-桉叶素、α-松油醇、香叶醇、反式橙花叔醇、原儿茶酸、香草酸的含量分别为15.8333～28.0000μL/g、29.1005～78.1996mg/g、6.7898～35.7977mg/g、0.0887～0.4013mg/g、0.1063～0.4080mg/g、3.7096～8.5331mg/g、0.2598～0.5996mg/g、0.3148～1.3241mg/g、0.2723～0.5764mg/g、9.3012～19.8185μg/g、8.1809～27.6663μg/g。熵权TOPSIS法分析结果显示，相对贴近度排名前3位的分别是云南保山7月、云南红河10月和云南文山9月产草果；相对贴近度排名后3位的分别是云南德宏9月、云南德宏11月、云南德宏12月产草果。结论云南保山（7月）、红河（10月）、文山（9月）产草果质量较优。 |
| ABSTRACT： | OBJECTIVE To evaluate the quality of Amomum tsao -ko from different origins and harvesting periods comprehensively. METHODS The contents of total volatile oil in A. tsao -ko were determined by volatile oil measurement method A stated in 2020 edition of Chinese Pharmacopoeia （part Ⅳ）；the contents of total flavonoids and total polyphenols in A. tsao -ko were determined by aluminum nitrate-sodium nitrite colorimetry and folin-ciocalteu method. The contents of α-pinene，β-pinene， 1，8-cineole，α-terpineol，geraniol and trans-nerolidol in the volatile oil of A. tsao -ko were determined by gas chromatography ；the contents of protocatechuate and vanillic acid in A. tsao -ko were determined by ulta high performance liquid chromatography. The above 11 indicators were selected ，and entropy weight TOPSIS method was used to comprehensively evaluate the quality of 16 batches of A. tsao -ko. RESULTS The contents of total volatile oil ，total flavonoids ，total polyphenols ，α-pinene，β-pinene， 1，8-cineole，α-terpineol，geraniol，trans-nerolidol，protocatechuate and vanillic acid in 16 batches of A. tsao -ko were 15.833 3- 28.000 0 μL/g，29.100 5-78.199 6 mg/g，6.789 8-35.797 7 mg/g，0.088 7-0.401 3 mg/g，0.106 3-0.408 0 mg/g，3.709 6-8.533 1 mg/g，0.259 8-0.599 6 mg/g，0.314 8-1.324 1 mg/g，0.272 3-0.576 4 mg/g，9.301 2-19.818 5 μg/g，8.180 9-27.666 3 μg/g， respectively. Entropy weight TOPSIS results showed that the top three of relative closeness rankings were A. tsao -ko produced by Yunnan Baoshan in July ，Yunnan Honghe in October ，Yunnan Wenshan in September ；the last three of relative closeness rankings were A. tsao -ko produced by Yunnan Dehong in September ，Yunnan Dehong in November ，Yunnan Dehong in December. CONCLUSIONS A. tsao -ko produced by Yunnan Baoshan in July ，Yunnan Honghe in October and Yunnan Wenshan in September present better quality. |
