Phytochemical Analysis and Gastroprotective Activity of the Root Bark from Maytenus robusta

“…In this context, plant extracts have been shown to produce promising results in the treatment of gastric ulcer [3,4]. Phytochemical studies carried out with plants belonging to the Maytenus genus have demonstrated the presence of different constituent classes, including flavonoids, pentacyclic triterpenes and sesquiterpenes, and alkaloids, which present important pharmacological profiles, such as antiulcerogenic, analgesic, antiinflammatory, antifungal, leishmanicidal and anti-HIV activities [5][6][7][8][9][10][11][12][13][14][15][16]. M. robusta, a species that is very well adapted to the south of Brazil, where it is known as "Cafezinho do mato", and also M. ilicifolia (Espinheira-santa), are used in folk medicine to treat stomach ulcers [6,13,17].…”

Leaf morphoanatomy of the medicinal Maytenus imbricata (Celastraceae): an ecological approach

“…Many of the chemical components isolated from its species have pharmacological properties (Din et al 2013, Duarte et al 2013, Moo-Puc et al 2014 (Silva et al 2009, Rodrigues et al 2012, M. aquifolium Mart., (Gonzalez et al 2001), M. salicifolia Reissek, (Magalhães et al 2011) and M. truncata Reissek, (Silva et al 2005a) are used in folk medicine to treat the same stomach illness, and have the same popular name "espinheira-santa" (Niero et al 2011). For these reasons it is necessary a careful quality control of raw material in the manufacture of drugs using Maytenus species and is required define anatomical key characters for the unambiguous species identification (Jacomassi & Machado 2004, Duarte & Debur 2005, Joffily & Vieira 2005, Nakamura et al 2013.…”
