【摘要】 对鲜天麻不同盐水杀青浓度和加工方法进行研究，探讨其加工后的饮片是否符合质量要求，为鲜天麻杀青及加工提供新技术。将鲜天麻置于0.03、0.06、0.09 g/mL盐水杀青10 d后采用传统加工、直接干燥、趁鲜加工3种加工方法得到天麻饮片，对其进行薄层鉴别、外观评价、浸出物、水分、灰分、酸不溶性灰分、二氧化硫残留量、亚硝酸盐及6种有效成分含量的测定。以天麻素、对羟基苯甲醇、巴利森苷A、巴利森苷B、巴利森苷C、巴利森苷E的质量分数、醇溶性浸出物和外观性状得分为考察指标，结合AHP-CRITIC复合权重法和化学计量法，对加工的天麻饮片进行综合评价。结果表明最优工艺为：0.03 g/mL盐水杀青10 d,脱盐后，斜切6 mm, 55℃干燥13 h。该加工工艺得到的天麻饮片综合评分最高；GA、HBA、PE、PB、PC含量，GA和HBA总量均为最高；薄层鉴别、浸出物、水分、二氧化硫残留量均符合要求，亚硝酸盐未检出。更多还原

【Abstract】 This study investigated the effects of different saline blanching concentrations and processing methods on fresh Gastrodia elata Bl., aiming to determine whether the processed decoction pieces meet quality standards and to provide a new processing technology for production areas. Fresh G.elata tubers were immersed in saline solutions with concentrations of 0.03, 0.06, and 0.09 g/mL for 10 days, followed by three processing methods: traditional processing, direct drying, and fresh-cut processing to obtain decoction pieces. Subsequently, thin-layer chromatography(TLC), appearance evaluation, moisture content, total ash, acid-insoluble ash, alcohol-soluble extractives, sulfur dioxide residue, nitrite content, and six active components were determined. Gastrodin(GA), p-hydroxybenzyl alcohol(HBA), parishin A, parishin B, parishin C, and parishin E, together with alcohol-soluble extract content and appearance scores, were used as evaluation indicators. The quality of the processed G.elata decoction pieces was comprehensively assessed using the AHP-CRITIC composite weighting method combined with chemometric analysis.The results showed that the optimal process was soaking fresh G.elata in a 0.03 g/mL saline solution for 10 days, followed by desalination, oblique slicing to 6 mm, and drying at 55 ℃ for 13 hours, which yielded the highest comprehensive score. Under this process, the contents of GA, HBA, PE, PB, and PC were highest, and the total amount of GA+HBA was also maximized. The TLC identification, alcohol-soluble extractives, moisture, and sulfur dioxide residue all met pharmacopoeial requirements, and nitrite was not detected.更多还原
