Pharmacologic studies on the active principles of calliandra portoricensis leaf extracts

Evaluation of antinociceptive, anti-inflammatory and antiulcerogenic activities of Maytenus ilicifolia

“…In the phytochemical evaluation carried out in the present study, the presence of condensed tannins and flavonoids was observed, as stated before. Our results are consisitent to those observed by Aguwa (1985), Ezaki et al (1985), Aguwa and Lawal (1988), Vilegas et al (1999), Leite et al (2001), Gonzalez and Di Stasi (2002) and Khennouf et al (2003) that suggest the antiulcerogenic activity of these compounds.…”

In vitroandin vivoimmunomodulatory and anti-ulcerogenic activities ofTeucrium ramosissimumextracts

“…There is a basis for expecting such effects; Galati et al, (1997, 2000) and Fernandez Puntero et al (1997 each have described the utility of Teucrium genus products to treat gastric disorder. In fact, the results of the studies of protection against ulcer formation in situ here were found to be consistent with those observed by Aguwa (1985), Ezaki et al (1985), Aguwa and Lawal (1988), Vilegas et al (1999), Leite et al (2001), Gonzalez and Di Stasi (2002) and Khennouf et al (2003) who each examined the anti-ulcerogenic properties of several types of natural products/by-products (e.g., Calliandra portoricensis, Rhigiocarya racemifera, Linderae umbellatae, Wilbrandia ebracteata, Maytenus ilicifolia, M. aquifolium, M. aquifolium, Quercus suber, and Q. coccifera). In each case, those Authors suggested that tannins, flavonoids, and polyphenols found in the natural products they examined may have been the agent(s) that imparted the observed anti-ulcerogenic effects, albeit by (as-yet) undefined mechanisms.…”

Plant use in the medicinal practices known as “strict diets” in Chazuta valley (Peruvian Amazon)

“…In addition, extracts and flavonoids isolated from other Calliandra species have demonstrated antimicrobial activity (Adewunmi and Marquis, 1983;Aguwa and Lawal, 1988;Awachie and Ugwu, 1997;Chiappeta and De Mello, 1984;Encarnacion and Garcia, 1991;Encarnacion et al, 1994), and an extract from Calliandra portoricensis showed CNS depressant activity (Adesina, 1982).…”
