is a perennial twining herb widely spread out arid and semiarid Tunisian regions. It is searched for its richness in enzymes, secondary metabolites, antifungal activity, and milk-clotting activity. Traditional use implies the fresh latex in wounding heals. The present study was aimed at identifying laticifer distribution in stems, leaves, and petioles. In the present study, the identification of latex extract's components and its valorisation by estimation of phenolic content, flavonoids, and antioxidant activity are conducted. Anatomical structures proved the presence of laticifers in the aerial parts of They are particularly observed along the pith and cortical parenchyma in stem, in leaf mesophyll, and in petiole phloem. Identified laticifers were characterized as nonarticulated. FTIR spectroscopy proves the presence of several functional groups in the latex and mainly the 1-4-isoprene monomer. Results suggested that latex contributes significantly as a source of phenol content (62.3 mg Eq GAE/g) and flavonoids (24.8 mg Eq QE/g). Scavenging free radicals of DPPH exhibited IC value of 12 g/ml. In conclusion, latex extracted from can be implied in industry as a natural rubber. It can be used, also, in medicine as a therapeutic agent.
是一种多年生缠绕草本植物，广泛分布于突尼斯干旱和半干旱地区。它因其富含酶、次生代谢物、抗真菌活性和凝乳活性而受到关注。传统用途表明新鲜乳胶原液可用于创伤愈合。本研究旨在确定茎、叶和叶柄中的乳管分布。本研究对乳胶提取物的成分进行了鉴定，并通过测定其酚类含量、类黄酮和抗氧化活性进行了评价。解剖结构证明了 的乳管存在于其地上部分。它们特别存在于茎的髓心和皮层薄壁组织、叶的叶肉和叶柄的韧皮部中。鉴定出的乳管是非节段性的。傅里叶变换红外光谱（FTIR）证明乳胶中存在多种官能团，主要是 1-4-异戊二烯单体。结果表明， 乳胶作为酚类含量（62.3mgEqGAEg）和类黄酮（24.8mgEqQEg）的来源具有重要意义。DPPH 自由基清除活性的 IC 值为 12g/ml。总之，从 中提取的乳胶可以作为天然橡胶应用于工业。它也可以在医学上用作治疗剂。
