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). |

甲醇提取可確定每100克新鮮西紅柿中含較好的胡蘿卜素3.39毫克到20.52毫克，新鮮辣椒中胡蘿卜素含量為2.59毫克到42.83毫克，在新鮮黃瓜中的含量則介于18.13毫克至33.86毫克之間。 在第三種提取液 - 丙酮中所獲得的胡蘿卜素值均較高，因此，丙酮提取每100克新鮮西紅柿中含2.99毫克到54.78毫克，新鮮辣椒中11.95毫克到74.70毫克，在新鮮黃瓜中13.94毫克到27.49毫克（表1） 。 比較三種胡蘿卜素提取方法所得結(jié)果，丙酮提取法在分析的蔬菜：西紅柿，辣椒和黃瓜中均取得了最佳的結(jié)果。胡蘿卜素提取數(shù)據(jù)結(jié)果表明，丙酮提取最好的變化系數(shù)分別為櫻桃西紅柿70.4％ ，普通西紅柿11.77 ％，辣椒91.27％ ，黃瓜 24.18％。甲醇提取系數(shù)的變化的結(jié)果略低于丙酮提取，櫻桃西紅柿為54.31％ ，普通西紅柿 16.25 ％，辣椒90.27％，黃瓜16.55％（見(jiàn)表2） 。 “variation coefficient”這詞我沒(méi)多少把握，其他的看著用吧。供參考。 |
