摘  要:
对红香椿的理化指标进行了测定,结果表明其水分含量为83.7%,粗蛋白、粗脂肪的含量分别为23.2%和10.4%(干基),富含人体必需氨基酸,苏氨酸、赖氨酸、亮氨酸、苯丙氨酸以及不饱和脂肪酸亚油酸和亚麻酸。采用响应面法研究了红香椿中总类黄酮的提取工艺,最佳提取工艺条件为:乙醇浓度82%、浸提温度60℃、料液比1:19、浸提15min,在此条件下提取率高达98.27%±0.31%,其总类黄酮的含量为3.1%(干基)。

摘  要:
In this study,the contents of the main ingredients in red Toona sinensis burgeon were measured,and the results showed that the contents of total water,protein and fat are 83.7%,23.2%(dry weight) and 10.4%(dry weight),respectively.Red Toona sinensis burgeon is rich in the necessary amino acids(threonine,lysine,leucine,and phenylalanine)and unsaturated fat acids(linoleic acid and linolenic acid).By using the response surface methodology,the optimal extraction condition of flavonoids from red Toona sinensis burgeon was determined as follows:taking 82% ethanol as extractant,ratio of extractant to material 19:1,temperature 60 ℃,and extraction time 15 min.Under these conditions,the yield of total flavonoids is 98.27% ± 0.31% and the total flavonoid content is 3.1%(dry weight).
