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.通過比較三種萃取值變異的葉綠素，甲醇和丙酮的提取達到了最好的結(jié)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.用乙醚提取的葉綠素是所有測試的蔬菜類中葉綠素提取量最低的，接近檢測的分光光度計的極限了。 Extraction with methanol resulted in high values of chlorophyll b in peppers and cucumbers; 甲醇的提取致使青椒和黃瓜的葉綠素的含量極高。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.每一百克新鮮青椒的葉綠素含量的波動范圍是2.25-63.45毫克，每一百克新鮮黃瓜的葉綠素含量范圍是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.而使用丙酮時，西紅柿的葉綠素萃取量就減少了，接近檢測設(shè)備的極值了，但是青椒和黃瓜的葉綠素含量人保持較高水平。 Results of the extraction of chlorophyll b showed that acetone solvent determined the best results followed by extraction with methanol.結(jié)果顯示，使用丙酮溶劑來萃取葉綠素優(yōu)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).葉綠素的決定因素的數(shù)據(jù)分析結(jié)果表明，用甲醇在圣女果中萃取的葉綠素含量是最高的，它的變異系數(shù)高達41.07%，其次是普通西紅柿的變異系數(shù)是55.97%，再次是青椒51.53%，黃瓜是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).在葉綠素萃取的實驗中，得到的用甲醇萃取的最佳變異系數(shù)分別是圣女果中13.79% ，普通西紅柿中19.57%，青椒中 66.57%，黃瓜中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).乙醇溶劑影響了胡蘿卜素的萃取量，因此在每一百克新鮮的西紅柿中胡蘿卜素的含量波動范圍是1.20-21.91毫克，而青椒和黃瓜的胡蘿卜素的萃取量極低。（表1） "coefficient of variation "由于此詞在不同領(lǐng)域的譯法不同，由于本人專業(yè)限制，因此暫時翻譯為“變異系數(shù)”，請作者自行斟酌，不適當請修改，謝謝！也歡迎廣大愛好翻譯的人士批評指正，謝謝。美博翻譯祝您國慶快樂！ |

樓上的翻譯不錯。 有一個關(guān)鍵地方，在此提出。樓上把chlorophyll a, chlorophyll b統(tǒng)統(tǒng)翻譯成葉綠素，這是不對的。應(yīng)分別翻譯成葉綠素a和葉綠素b，它們分別是葉綠體色素的兩種重要形式，具有不同的結(jié)構(gòu)。此外還有葉綠素c1，c2，d，f等。 關(guān)于葉綠素，請參見Wikipedia https://en.wikipedia.org/wiki/Chlorophyll。 |
