摘要
为了进一步提升连翘叶的开发,将一芽二叶至一芽三叶的连翘嫩叶加工成连翘叶绿茶。对连翘叶绿茶、桑叶绿茶和信阳毛尖的活性成分进行分析。分析结果表明:连翘叶绿茶含水量为36 mg/g。微量元素含量较高,茶多酚为172 mg/g,氨基酸为13.23 mg/g,咖啡碱29.3 mg/g,总黄酮26.48 mg/g,总木脂素19.76 mg/g,以及总三萜酸6.15 mg/g。具有较强的清除DPPH自由基的能力,这表明连翘叶绿茶含有丰富的对人体具有保健作用的活性成分。
The Forsythia Suspensa leave green teas were processed with two leaves and one bud or three leaves and one bud,in order to further enhance the exploitation of Forsythia Suspensa leaves. Active ingredients in Forsythia Suspensa leave green tea,mulberry leave tea and Xinyangmaojian were analyzed. The results show that the moisture content of Forsythia Suspensa leave green tea is 36 mg / g. The contents of microelements are higher with 172 mg / g tea polyphenols,13. 23 mg / g amino acid,29. 3 mg / g caffeine,26. 48 mg / g total flavonoids,19. 76 mg / g total lignans and 6. 15 mg / g total triterpene acid. These have stronger scavenging effects in DPPH radical scavenging. So Forsythia Suspensa leave green tea contains rich active ingredients with health-care functions.
