摘要
目的:明确鼓槌石斛花成分、抗氧化能力和食用安全性,促进其开发利用。方法:以50℃烘干后的鼓槌石斛花为研究对象,根据相关国家标准或委托第三方检测机构对其营养成分、活性成分、安全性指标进行检测,应用试剂盒对其抗氧化能力进行检测。结果:鼓槌石斛花含有多种功能性化合物,多糖含量高达(25.25±1.36)g/100 g,可溶性糖含量为(52.09±1.47)g/100 g;鼓槌石斛花醇提物对羟基自由基、超氧阴离子、ABTS阳离子自由基、DPPH自由基的具有清除能力,半抑制浓度(IC50)分别为0.0544 mg·mL^(-1)、0.0959 mg·mL^(-1)、0.0054 mg·mL^(-1)和0.0025 mg·mL^(-1);鼓槌石斛花4种重金属、196种农药残留和2种微生物均未超标。结论:鼓槌石斛花具有较高的营养价值和保健功能,可作为食用花卉进行开发利用。
Objective:To clarify the components,antioxidant activity,and food safety of the flowers of Dendrobium chrysotoxum,and promote their development and utilization.Method:The flowers of D.chrysotoxum dried at 50℃were taken as the research object.According to relevant national standards or third-party testing institutions commissioned,their nutritional components,active ingredients,and safety indicators were tested.The antioxidant capacity was tested using a reagent kit.Result:The flowers of D.chrysotoxum contain multiple functional compounds,with a polysaccharide content of up to(25.25±1.36)g/100 g and a soluble sugar content of(52.09±1.47)g/100 g;the alcohol extract of the flowers of D.chrysotoxum has the ability to scavenge hydroxyl radicals,superoxide anions,ABTS cation radicals,and DPPH radicals,with half inhibitory concentrations(IC_(50))of 0.0544 mg·mL^(-1),0.0959 mg·mL^(-1),0.0054 mg·mL^(-1),and 0.0025 mg·mL^(-1),respectively;the 4 heavy metals,196 pesticide residues,and 2 microorganisms in flowers of D.chrysotoxum did not exceed the standard.Conclusion:The flowers of D.chrysotoxum has high nutritional value and health functions,and can be developed and utilized as an edible flower.
