Methanol extraction determined higher levels of carotene pigment in tomatoes,varying between 3.39 mg/100 g and 20.52 mg/100 g in fresh product, in pepper the
concentrations of carotene were between 2.59 mg/100 g and 42.83 mg/100 g in fresh product,and in cucumbers the concentrations obtained ranged from 18.13 mg/100 g and 33.86 mg/100g fresh product.
In the third extracting solution – acetone, the obtained carotene values were higher,thus in tomatoes were between 2.99 mg/100 g and 54.78 mg/100 g fresh product, in peppers between 11.95 mg/100 g and 74.70 mg/100 g fresh product, and in cucumbers the concentrations ranged from 13.94 mg/100 g fresh product and 27.49 mg/100 g fresh product (Table 1).
Comparing the results of the three extractions of carotene, acetone extraction determined the best results in all analyzed vegetables: tomatoes, peppers and cucumbers. Statistical interpretation of results of carotene showed that acetone extraction resulted in the best variation coefficient respectively 70.4% at cherry tomatoes, 11.77% at common tomatoes, 91.27% at peppers and 24.18% at cucumbers. Methanol extraction also showed coefficient of variation of the results slightly lower than for acetone extraction, respectively 54.31% for cherry tomatoes, 16.25% for common tomatoes, 90.27% for peppers and 16.55% for cucumbers (Table 2).

甲醇提取可确定每100克新鲜西红柿中含较好的胡萝卜素3.39毫克到20.52毫克,新鲜辣椒中胡萝卜素含量为2.59毫克到42.83毫克,在新鲜黄瓜中的含量则介于18.13毫克至33.86毫克之间。
在第三种提取液 - 丙酮中所获得的胡萝卜素值均较高,因此,丙酮提取每100克新鲜西红柿中含2.99毫克到54.78毫克,新鲜辣椒中11.95毫克到74.70毫克,在新鲜黄瓜中13.94毫克到27.49毫克(表1) 。
比较三种胡萝卜素提取方法所得结果,丙酮提取法在分析的蔬菜:西红柿,辣椒和黄瓜中均取得了最佳的结果。胡萝卜素提取数据结果表明,丙酮提取最好的变化系数分别为樱桃西红柿70.4% ,普通西红柿11.77 %,辣椒91.27% ,黄瓜 24.18%。甲醇提取系数的变化的结果略低于丙酮提取,樱桃西红柿为54.31% ,普通西红柿 16.25 %,辣椒90.27%,黄瓜16.55%(见表2) 。

“variation coefficient”这词我没多少把握,其他的看着用吧。供参考。
既然选择了,就坚持下去!
