| Abstract: | Objective: To develop a stable and simple method to measure the content of aloe oligosaccharides. Methods: After the conversion coefficient of aloe oligosaccharides to glucose was obtained, the content of aloe oligosaccharides was measured by phenol sulfuric acid method. Results: The correlation coefficient of standard curve is 0.9993, the recovery rate is 95.3% and RSD is 1.23%. Conclusion: The method can be applied to aloe and aloe products. |
