The study was conducted to compare the chemical composition and bioactive compounds of leaves from different mulberry species grown in Syria (, , , and sp). The leaves were collected in July 2022 and their proximate composition (moisture, ash, lipids, and protein), total polyphenol content (TPC), ascorbic acid, and antioxidant activity, as measured by ferric reducing antioxidant power (FRAP), were investigated. The results showed that the moisture, ash, and fat content ranged from 61.84 to 71.17%, 12.87 to 17.61%, and 3.82 to 9.68% dry weight (DW), respectively. The phenolic concentration of leaves from four different mulberry cultivars varied significantly, from 164.9 () to 461.5 gallic acid equivalents mg/100 g DW (). The antioxidant activity of mulberry leaves ranged from 122 to 166.3 meq ascorbic acid/100 g DW and was arranged as follows: > sp > > . According to the findings, mulberry leaves could be used to create new food supplements, functional foods, and medical applications.
本研究旨在比较叙利亚种植的不同桑树品种（、、、种）叶片的化学成分和生物活性化合物。2022年7月采集叶片，并对其近似成分（水分、灰分、脂质和蛋白质）、总多酚含量（TPC）、抗坏血酸以及通过铁还原抗氧化能力（FRAP）测定的抗氧化活性进行了研究。结果表明，水分、灰分和脂肪含量分别为干重（DW）的61.84%至71.17%、12.87%至17.61%和3.82%至9.68%。四个不同桑树品种叶片的酚类浓度差异显著，从164.9（）到461.5没食子酸当量mg/100 g DW（）。桑叶的抗氧化活性为122至166.3 meq抗坏血酸/100 g DW，排列顺序如下：>种>种>种。根据研究结果，桑叶可用于开发新的食品补充剂、功能性食品和医学应用。
