L. is one of the oldest trees belonging to the mulberry family. It has both nutritional and medicinal benefits, as it is a source of potential bioactive compounds. Fig leaves were collected at four maturation stages, to evaluate the variation in polyphenolic compounds, antioxidant activity, and different pigments level. Polyphenols were identified using HPLC-DAD. Different pigments level, total phenolic contents, and radical scavenging activity were quantified. The HPLC analysis revealed the presence of fourteen polyphenolic compounds in the fig leaves. Quercetin-3-glucoside, caftaric acid, quercetin-3, 7-diglucoside, and coumaroyl-hexose were the major phenolic compounds. Kaempferol-3-O-sophorotrioside, cichoric acid and sinapic acid glucoside were identified for the first time. Significant quantitative changes were observed during maturation, particularly in polyphenolic compounds. There were significant changes in pigments level, total phenolic contents, and radical scavenging activity. It was observed that fig leaves are a rich source of polyphenolic compounds during all stages of maturation.
L.是桑科最古老的树木之一。它具有营养和药用价值，因为它是潜在生物活性化合物的来源。在四个成熟阶段采集无花果叶，以评估多酚类化合物、抗氧化活性和不同色素水平的变化。使用高效液相色谱-二极管阵列检测器（HPLC-DAD）鉴定多酚。对不同色素水平、总酚含量和自由基清除活性进行了定量分析。HPLC分析表明无花果叶中存在14种多酚类化合物。槲皮素-3-葡萄糖苷、咖啡酸、槲皮素-3,7-二葡萄糖苷和香豆酰己糖是主要的酚类化合物。山奈酚-3-O-槐三糖苷、菊苣酸和芥子酸葡萄糖苷首次被鉴定出来。在成熟过程中观察到显著的定量变化，特别是在多酚类化合物方面。色素水平、总酚含量和自由基清除活性有显著变化。观察到无花果叶在成熟的所有阶段都是多酚类化合物的丰富来源。
