Abstract :Polyphenol profiles can suffer quali-quantitative modifications as the plant modifies its phenological condition. The objective of this work was to determine if there is a rhythm of production in the synthesis of polyphenols according to the phenological condition in the leaves, roots, and rhizomes of Smilax campestris Griseb. The plant material analysed corresponded to individuals of a colony of S. campestris collected in different phenological conditions. Standard methodology was used for the chromatographic profiles of flavonols (kaempferol, quercetin, isorhamnetin, and their glycosides) and proanthocyanidins (procyanidin and propelargonidin) and quantification of total phenol, condensed tannins, and flavonols. Appearance of metabolic changes was established in the studied organs of S. campestris according to the phenological condition.
