Morphoanatomical and Phytochemical Study of Buddleja thyrsoides Lam. (Scrophulariaceae) Leaves

This work deals with foliar morphology, anatomy and phytochemical profile of Buddleja thyrsoides Lam. (Scrophulariaceae) leaves. The leaves present a lanceolate-linear shape, straight adaxial face; the margin is serrate to sub-entire and little revolute close to the basis. The epidermis is uniseriate, with the epidermal cells of the adaxial face bigger than those of abaxial face, stomata and trichomes in abaxial face. The mesophyll is heterogeneous, bifacial and presents branched cells and crystals in druse form. The vascular system is of the open collateral type. These characters are significant in the botanical quality control of this species. Phytochemical screening revealed the presence of alkaloids, flavonoids, cumarins, anthocyanic heterosides, and saponins.
