“…Euphorbiaceae is among the largest families of Angiosperms (flowering plants), comprising 228 genera and 6547 accepted species names [1] . Many of its species are recognized as traditional medicinal plants, such as Phyllanthus niruri, used to treat kidney stones (nephrolithiasis), and Croton campestris, used as a laxative, anti-syphilitic and for the treatment of biliary duct infections [2,3] . The oils and latex of many species have also glaziovii, Manihot esculenta, and Manihot utilissima are used in the food industry [4] .…”

“…Euphorbia is the largest genus in Euphorbiaceae family with approximately 2000 species [1] . As example of medicinal use, it can be mentioned Euphorbia tirucalli, whose latex has antitumoral and anti-syphilitic properties [2] and Euphorbia hirta that has been used traditionally for respiratory ailments (cough, coryza, bronchitis, and asthma), worm infestations in children, digestive problems, and tumors [6] . Euphorbia heterophylla Linnaeus is an annual plant reproducing by seeds, latescent, erect, being able to reach 30-80 cm height.…”

Many of Euphorbiaceae species are recognized as traditional medicinal plants and the oils and latex of many species have also economic importance. In fact, Euphorbia heterophylla L., belonging to this family and popularly known in Brazil as “leiteira”, “flor-de-poetas” and wild poinsettia, has been used traditionally in Africa and India to treat many kinds of health disorders. However, the chemical composition of this species has been little studied so far. In the present investigation, the flavonoids quercitrin (quercetin 3-O-α-L-rhamnopyranoside), hyperin (quercetin 3-O-β-D-galactopyranoside), isoquercitrin (quercetin 3-O-β-D-glucopyranoside) and isoquercitrin 6”-malonate (quercetin 3-O-β-D-(6”-malonate)-glucopyranoside) were isolated from an ethyl acetate partition of aqueous ketone extract from E. heterophylla leaves. The dehydroellagitannins geraniin and phyllantusiin D as well as 1,2,3,4,6- penta-O-galloyl- β-D-glucopyranoside, caffeic acid and the coumarin aesculetin (6,7-dihydroxycoumarin) were also isolated. All the compounds were characterized by spectroscopic methods such as 1H and 13C-NMR, COSY, HETCOR, APT and by comparison with literature data. The presence of these substances of relevant bioactivity is reported for the first time in E. heterophylla through our study supporting in this way the medicinal use of this specie.

Background:Pluchea quitoc DC. (Asteraceae), a medicinal plant known as “quitoco,” “caculucage,” “tabacarana” and “madre-cravo,” is indicated for inflammatory conditions such as bronchitis, arthritis, and inflammation in the uterus and digestive system.Objective:This study evaluated the analgesic and anti-inflammatory activities of the triterpenes compounds obtained from P. quitoc aerial parts.Materials and Methods:The triterpenes compounds β-amyrin, taraxasterol and pseudo-taraxasterol in a mixture (T); β-amyrin, taraxasterol and pseudo-taraxasterol acetates in a mixture (Ta); β-amyrin, taraxasterol, pseudo-taraxasterol acetates in a mixture with β-amyrin, taraxasterol and pseudo-taraxasterol myristates (Tafe) were analyzed in the models of nociception and inflammation. The evaluation of antinociceptive activity was carried out by the acetic acid-induced writhing and tail-flick tests while leukocyte migration to the peritoneal cavity was used for anti-inflammatory profile.Results:The oral administration of T or Tafe (40 mg/kg and 70 mg/kg) and Ta (70 mg/kg) to mice reduced acetic acid-induced writhing. The tail-flick response of mice was not affected by T or Tafe (40 mg/kg). T or Tafe (40 mg/kg) and Ta (70 mg/kg) also inhibited peritoneal leukocyte infiltration following the injection of carrageenan.Conclusion:The results demonstrate the anti-inflammatory and peripheral antinociceptive activity of the triterpenes β-amyrin, taraxasterol, and pseudo-taraxasterol that were decreased when these were acetylated; while the acetylated triterpenes in mixture with myristyloxy triterpenes improved this activity. These compounds seem, at least in part, to be related to the plant’s reported activity.SUMMARYThe mixtures of hydroxylated, acetylated, and myristate triterpenes isolated from hexanic extracts of Pluchea quitoc DC. were analyzed in the models of nociception and inflammation in mice. The results demonstrate the anti-inflammatory and peripheral antinociceptive activity of the triterpenes β-amyrin, taraxasterol, and pseudo-taraxasterol. This study showed too that the activity of triterpenes may be decreased by their being acetylated, while the acetylated triterpenes in mixture with myristate triterpenes improved this activity.Abbreviations Used: T: Triterpenes compounds β-amyrin, taraxasterol, and pseudo-taraxasterol in a mixture, Ta: Triterpenes compounds β-amyrin, taraxasterol and pseudo-taraxasterol acetates in a mixture, Tafe: Triterpenes compounds β-amyrin, taraxasterol, pseudo-taraxasterol acetates in a mixture with β-amyrin, taraxasterol and pseudo-taraxasterol myristates, Ctrl: Control, Indo: Indomethacin, Dexa: Dexamethasone, EtOAc: Ethyl acetate, MeOH: Methanol.
