Comparing the values of the three extraction variants of chlorophyll a, best results were obtained with methanol and acetone.Chlorophyll b extraction with diethyl ether registered low results obtained in all the tested vegetables, being close to the limit of detection of the spectrophotometer. Extraction with methanol resulted in high values of chlorophyll b in peppers and cucumbers; the peppers values ranged between 2.52 mg/100 g and 63.45 mg/100 g fresh product and the cucumbers values ranged from 254.90 mg/100 g to 412.31 g/100 g fresh product. When using acetone, the extraction of chlorophyll b is decreased in tomatoes, near the limit of detection of the device and high in peppers and cucumbers. Results of the extraction of chlorophyll b showed that acetone solvent determined the best results followed by extraction with methanol. Statistical interpretation of the results for chlorophyll a determination showed that the best results were obtained from extraction with methanol where the coefficient of variation was 41.07% in cherry tomatoes, 55.97% in common tomatoes, 51.53% in peppers and 52.15% in cucumbers (Table 2). In the case of chlorophyll b extraction, the best coefficients of variation were obtained using extraction with methanol respectively 13.79% in cherry tomatoes 19.57% in common tomatoes, 66.57% in peppers and 47.95% in cucumbers (Table 2). Diethyl ether solvent determined a different extraction of carotene, so at tomatoes the values ranged between 1.20 mg/100 g and 21.91 mg/100 g in fresh product, while at peppers and cucumbers low extraction values were obtained (Table 1). |

Comparing the values of the three extraction variants of chlorophyll a, best results were obtained with methanol and acetone.通过比较三种萃取值变异的叶绿素，甲醇和丙酮的提取达到了最好的结果。Chlorophyll by extraction with diethyl ether registered low results obtained in all the tested vegetables, being close to the limit of detection of the spectrophotometer.用乙醚提取的叶绿素是所有测试的蔬菜类中叶绿素提取量最低的，接近检测的分光光度计的极限了。 Extraction with methanol resulted in high values of chlorophyll b in peppers and cucumbers; 甲醇的提取致使青椒和黄瓜的叶绿素的含量极高。the peppers values ranged between 2.52 mg/100 g and 63.45 mg/100 g fresh product and the cucumbers values ranged from 254.90 mg/100 g to 412.31 g/100 g fresh product.每一百克新鲜青椒的叶绿素含量的波动范围是2.25-63.45毫克，每一百克新鲜黄瓜的叶绿素含量范围是254.9-412.31毫克。 When using acetone, the extraction of chlorophyll b is decreased in tomatoes, near the limit of detection of the device and high in peppers and cucumbers.而使用丙酮时，西红柿的叶绿素萃取量就减少了，接近检测设备的极值了，但是青椒和黄瓜的叶绿素含量人保持较高水平。 Results of the extraction of chlorophyll b showed that acetone solvent determined the best results followed by extraction with methanol.结果显示，使用丙酮溶剂来萃取叶绿素优于使用甲醇萃取。 Statistical interpretation of the results for chlorophyll a determination showed that the best results were obtained from extraction with methanol where the coefficient of variation was 41.07% in cherry tomatoes, 55.97% in common tomatoes, 51.53% in peppers and 52.15% in cucumbers (Table 2).叶绿素的决定因素的数据分析结果表明，用甲醇在圣女果中萃取的叶绿素含量是最高的，它的变异系数高达41.07%，其次是普通西红柿的变异系数是55.97%，再次是青椒51.53%，黄瓜是52.15%。（表2） In the case of chlorophyll b extraction, the best coefficients of variation were obtained using extraction with methanol respectively 13.79% in cherry tomatoes 19.57% in common tomatoes, 66.57% in peppers and 47.95% in cucumbers (Table 2).在叶绿素萃取的实验中，得到的用甲醇萃取的最佳变异系数分别是圣女果中13.79% ，普通西红柿中19.57%，青椒中 66.57%，黄瓜中47.95%。（表2） Diethyl ether solvent determined a different extraction of carotene, so at tomatoes the values ranged between 1.20 mg/100 g and 21.91 mg/100 g in fresh product, while at peppers and cucumbers low extraction values were obtained (Table 1).乙醇溶剂影响了胡萝卜素的萃取量，因此在每一百克新鲜的西红柿中胡萝卜素的含量波动范围是1.20-21.91毫克，而青椒和黄瓜的胡萝卜素的萃取量极低。（表1） "coefficient of variation "由于此词在不同领域的译法不同，由于本人专业限制，因此暂时翻译为“变异系数”，请作者自行斟酌，不适当请修改，谢谢！也欢迎广大爱好翻译的人士批评指正，谢谢。美博翻译祝您国庆快乐！ |

楼上的翻译不错。 有一个关键地方，在此提出。楼上把chlorophyll a, chlorophyll b统统翻译成叶绿素，这是不对的。应分别翻译成叶绿素a和叶绿素b，它们分别是叶绿体色素的两种重要形式，具有不同的结构。此外还有叶绿素c1，c2，d，f等。 关于叶绿素，请参见Wikipedia https://en.wikipedia.org/wiki/Chlorophyll。 |
