蒽酮/苯酚 - 硫酸法测定紫皮石斛多糖的条件
Conditions for anthrone/phenol - vitriolic colorimetry in determining polysaccharides of Dendrobium devonianum
分别研究蒽酮/苯酚 - 硫酸法测定紫皮石斛多糖的方法中显色溶液用量、显色温度和显色时间对吸光度值的影响.采用响应面法拟合优化影响人工大棚种植紫皮石斛多糖测定吸光度值的因素.实验数据显示,用蒽酮 - 硫酸法测定人工大棚种植紫皮石斛多糖吸光度值时,溶液显色时间影响最大,蒽酮溶液用量次之,显色温度影响最小;而使用苯酚 - 硫酸法进行测定时,苯酚溶液用量影响最大,显色时间次之,影响最小的是显色温度.多糖所制备的标准曲线拟合良好,精密度高、稳定好、回收率高,故2种测定方法在优化最佳实验条件下进行,均可作为测定人工大棚种植紫皮石斛多糖质量浓度的测定方法.使用2种测定方法分别测定铁皮石斛和紫皮石斛多糖的质量浓度时,实验数据存在较大差异.
The effects of the volume of chromogenic solution, chromogenic temperature, and chromogenic time on the absorbance values were investigated separately using anthrone/phenol - vitriolic colorimetry for the determination of polysaccharides in Dendrobium devonianum. Response surface methodology was applied to model and optimize the factors influencing the absorbance of polysaccharides in artificially greenhouse - cultivated D. devonianum. Experimental results showed that in the determination of polysaccharides in artificially greenhouse - cultivated D. devonianum using the anthrone - sulfuric acid method, chromogenic time had the greatest effect on the absorbance, followed by the amount of anthrone solution, and finally the chromogenic temperature. In contrast, the application of the phenol - sulfuric acid method revealed that the volume of phenol solution exerted the greatest influence on the absorbance, followed by the chromogenic time, while the chromogenic temperature demonstrated the least effect. Both methods produced well - fitted standard curves with high precision, good stability, and high recovery rates under optimized conditions, confirming their suitability for determining polysaccharide concentrations in artificially greenhouse - cultivated D. devonianum. Significant discrepancies were observed in the experimental data with the application of these two methods for determining polysaccharide concentrations in D. officinale and D. devonianum, respectively.
