【 摘 要 】

In this study, pectin was extracted from aloe peel dried powder using acid extraction and alcohol precipitation method. The results showed that the amount of acid-insoluble ash, galacturonic acid, the loss on drying of pectin was 12.72%, 10.791% and 9.48%, respectively. There were several monosaccharides in the pectin, with the amount order of mannose > glucose > galactose > arabinose > rhamnose > fucose. This suggests that the method was suitable for the extraction of pectin from the aloe peel, but it still needs to be improved. Furthermore, the obtained aloe pectin had obvious ability of anti-oxidant, indicating that it might be a promising material for food and medicine. Our study will pave a new way for handling the aloe peel resource in the future.
