Friedelanes and Triterpenoid Quinone Methides fromHippocratea exclesa¹

The in-vivo antimalarial activities ofUvaria chamaeandHippocratea africana

“…obs.). Fridelanes, triterpenoid quinone methides, tingenone, caleastrol, pristimevin, excelsine, friedelin, canophyllol, canoplyllal, canophyllic acid and sesquiterpene alkaloids have all been previously isolated from H. excelsa (Calzada et al, 1991;Calzada and Mata, 1995;Furukawa et al, 2002), a North American species that is known to have anti-inflamatory and antibacterial properties (Perez et al, 1995;Alanis et al, 2005). The present study appears to be the first confirmation that the root of H. africana has significant antimalarial activity in vivo.…”

Antioxidant Quinonemethide Triterpenes from Salacia campestris

“…± Quinonemethide triterpenes are natural products of occurrence restricted to Hippocrateaceae and Celastraceae families. Several representatives of this class are claimed to be medicinally useful [1] [2], as antimicrobial [3 ± 5], anticancer [4] [6] [7], antimalarial [8], and spermicidal compounds [9]. Some Salacia species, e.g., S. reticulata, S. oblonga, and S. chinesis, have long been used in India, Sri-Lanka, and China, respectively, as traditional medicines for treating rheumatism and skin diseases, and for their anti-inflammatory properties as well.…”
