摘要:

基于熵值-综合评分法研究趁鲜切制云当归在4种干燥条件(晒干和40、50、60 ℃热风干燥)下的药效成分变化,并对其微生物群落组成和药效成分之间的变化规律进行相关性分析。利用电子鼻量化云当归气味并进行主成分分析;测定其挥发油、阿魏酸、藁本内酯、多糖、总酚、总黄酮6个药效成分的含量;通过DPPH法和ABTS法评价其自由基清除能力;采用16S和ITS微生物高通量测序揭示其趁鲜切制干燥过程中微生物群落组成变化,对“微生物-成分”进行相关性分析。结果显示,晒干样品综合评分最优,其次为40 ℃热风干燥,其性状(翘片率、气味),药效成分(挥发油、阿魏酸、藁本内酯、多糖、总酚、总黄酮)及抗氧化活性(DPPH、ABTS自由基清除能力)保留最佳。此外,16S、ITS微生物测序表明,干燥条件显著影响微生物群落组成,真菌群落变化占主导地位,其中曲霉菌属、沙雷菌属、ApiotrichumNaganishia等与成分含量变化密切相关。综上,在规模化生产中建议采用40 ℃热风干燥以平衡干燥效率与云当归药材质量,本研究也为优化云当归干燥工艺及其干燥过程中“微生物-成分”相互作机制研究提供理论依据。

Abstract:

Based on the entropy-comprehensive scoring method, the changes of pharmacodynamic components of fresh-cut Angelicae Sinensis Radix from Yunnan (YASR) under four drying conditions (sun drying, 40, 50, 60 ℃ hot air drying ) were studied, and the correlation between microbial community composition and pharmacodynamic components was analyzed. The electronic nose was used to quantify the odor of YASR and principal component analysis was performed. The contents of volatile oil, ferulic acid, ligustilide, polysaccharide, total phenols and total flavonoids were determined. The free radical scavenging ability was evaluated by the DPPH method and the ABTS method. The 16S and ITS microbial high-throughput sequencing was used to reveal the changes in microbial community composition during the fresh-cut drying process, and the correlation analysis of “microorganism-component” was carried out. The results showed that the comprehensive score of sun-dried samples was the best, followed by hot air drying at 40 °C. Their traits (warping rate, odor), pharmacodynamic components (volatile oil, ferulic acid, ligustilide, polysaccharide, total phenols, total flavonoids) and antioxidant activity (DPPH, ABTS free radical scavenging activity) were the best. 16S and ITS microbial sequencing showed that drying conditions significantly affected the composition of microbial community, and the change of fungal community was dominant. Among them, Aspergillus, Serratia, Apiotrichum and Naganishia were closely related to the change of component content. In summary, it is recommended to use 40 ℃ hot air drying in large-scale production to balance the drying efficiency and the quality of YASR. This study also provides a theoretical basis for optimizing the drying process of YASR and the mechanism of “microorganism-component” interaction during the drying process.
