桦褐孔菌人参复配粉提取工艺优化及其对小鼠脾细胞CD69表达的影响
Optimization of the extraction process of Inonotus obliquus and Ginseng compound powder and its effect on CD69 expression in mouse splenocytes
目的 本研究旨在优化桦褐孔菌人参复配粉的提取工艺,并评价其对脾细胞早期活化标志CD69表达的影响。 方法 以总多糖提取率为指标,采用L9(34)交互作用实验考察提取时间、用水量、提取次数对总多糖提取率的影响,确定桦褐孔菌人参复配粉的最佳提取工艺。提取小鼠原代脾细胞,CCK-8法测定桦褐孔菌人参复配粉对小鼠脾细胞的活力;设置阴性对照组、荧光减一(FMO)对照组、刀豆蛋白A(ConA)组(2.5 μg·mL-1)及桦褐孔菌人参复配粉组(100 μg·mL-1),流式细胞术检测CD69阳性细胞率。 结果 最佳提取工艺为用水量10倍,提取3次,每次1 h,验证实验多糖提取率为1.893%±0.064%。CCK-8实验显示复配粉浓度100 μg·mL-1时,细胞活力达190.01%±11.95%(P<0.000 1)。流式细胞术结果显示,桦褐孔菌人参复配粉能够诱导自然杀伤(NK)细胞、巡逻单核细胞和炎性单核细胞的CD69表达显著上调,而几乎不触发CD4+ T细胞、CD8+ T细胞、B细胞活化。 结论 优化的桦褐孔菌人参复配粉提取工艺为10倍用水量,提取3次,每次1 h,工艺稳定可行,所得复配粉在体外可诱导NK细胞、单核细胞早期活化,具有免疫增强潜力。
Objective To optimize the extraction process of Inonotus obliquus and Ginseng compound powder and to evaluate its effect on the expression of the early activation marker CD69 in splenocytes. Methods Using the extraction yields of total polysaccharides as indicators, an L9(34) interaction experiment was conducted to investigate the effects of extraction time, water volume, and number of extraction cycles on the extraction yields of total polysaccharides, thereby determining the optimal extraction process for Inonotus obliquus and Ginseng compound powder. Primary mouse splenocytes were isolated. The cell viability of Inonotus obliquus and Ginseng compound powder on mouse splenocytes was assessed by Cell Counting Kit-8 (CCK-8) assay. The negative control group, the fluorescence minus one (FMO) control group, the Concanavalin A (ConA) group (2.5 μg·mL-1), and the Inonotus obliquus and Ginseng compound powder group (100 μg·mL-1) were set up. The percentage of CD69‑positive cells was detected by flow cytometry. Results The optimal extraction process was water addition of 10 times the material weight, extraction for 3 cycles and 1 hour per cycle, and verification experiments showed that the extraction rate of polysaccharides was 1.893%±0.064%. The CCK-8 assay indicated that at a concentration of 100 μg·mL-1, the cell viability reached 190.01%±11.95% (P<0.000 1). Flow cytometry results showed that the Inonotus obliquus and Ginseng compound powder significantly upregulated CD69 expression in natural killer (NK) cells, patrolling monocytes, and inflammatory monocytes, while barely triggering the activation of CD4⁺ T cells, CD8⁺ T cells, or B cells. Conclusion The optimized extraction process for the Inonotus obliquus and Ginseng compound powder is extraction with 10-fold water for 3 cycles of 1 hour each. This process is stable and feasible. The resulting compound powder can induce early activation of NK cells and monocytes in vitro, demonstrating potential for immune enhancement.
