摘要
马铃薯块茎在不同温度和光照条件下贮藏6～18 d,用乙醇-乙酸法提取块茎皮中的α-茄碱,用高效液相色谱法测定其含量,研究块茎皮中龙葵素含量的变化。结果表明,在有光照、贮藏温度为8,15,25℃条件下贮藏6 d,样品中α-茄碱的含量分别为1.35%,4.96%和9.67%;在有光照、贮藏温度15℃的条件下,贮藏时间为6,12,18 d,样品中α-茄碱的含量分别为4.96%,8.78%和12.76%;在25℃、贮藏时间6 d条件下,有光照和无光照处理的样品中α-茄碱含量分别为9.67%和7.61%。块茎皮中的α-茄碱含量随贮藏温度和时间的增加而增加,光照条件下块茎皮中的α-茄碱含量明显增加。
Changes in solanine content in the tuber peel of potato （Solanum tuberosum L.） were studied under different temperature and light conditions and storage periods. Solanine was extracted by ethanol-acetic acid, and measured by High Performance Liquid Chromatography. The contents of solanine in peel of tuber under the store temperature of 8, 15 and 25 ℃ for 6 days combined with light illumination were, respectively, 1.35%, 4.96% and 9.67%. The contents of solanine in skin of tuber under the storage period of 6, 12 and 18 d at 15℃ with light were, respectively, 4.96%, 8.78%, and 12.76%. The contents of solanne in skin of tuber stored at 25℃ for 6 d with and without light were, respectively, 9.67% and 7.61%. The contents of solanne in skin of tuber increased with storage temperature and period, and noticeably increased under light.
