In this paper, the phytochemical analysis on the inflorescences (flowers and bracts) of a sample of Tilia tomentosa collected from an isolated population in Central Italy, was reported for the first time. Thirteen compounds (oleanolic acid, maslinic acid, apigenin, luteolin, kaempferol, quercetin, kaempferol-3-O-glucoside, quercetin-3-O-glucoside, rutin, tiliroside, ellagic acid, shikimic acid and quinic acid), belonging to several different classes of natural products, were identified on the basis of spectroscopic and spectrometric analysis. This sample was found to be mainly composed by flavonoids, followed by organic acids and pentacyclic triterpenes. The chemosystematic aspects of the identified components were also discussed, together with their pharmacologic relevance with respect to the traditional medicinal uses of this plant material.
