We investigated the anti-inflammatory activity ofSenecio salignus. This medicinal plant is often used in Mexico for the treatment of fever and rheumatism. Chloroform and methanol extracts of the plant were tested on 12-O-tetradecanoylphorbol-13-acetate- (TPA-) induced edema in mice ears. The methanol extract of the plant inhibited edema by36±4.4% compared with the control, while the chloroform extract exhibited an even greater level of inhibition (64.1%). The chloroform extract was then fractionated, and the composition of the active fraction was determined by GC-MS. The anti-inflammatory activity of this fraction was then tested on TPA-induced ear edema in mice, and we found that the active fraction could inhibit edema by 46.9%. The anti-inflammatory effect of the fraction was also tested on carrageenan-induced paw edema in rats at doses of 100 mg/kg; a58.9±2.8% reduction of the edema was observed 4 h after administration of carrageenan, and the effect was maintained for 5 h.

Ximenia americana or “ameixa-do-sertão” is a plant used in the folk medicine of Northeast-Brazil in inflammatory and painful processes. The literature has shown anti-inflammatory and antinociceptive activities for the aqueous or hydroalcoholic extracts and polysaccharide fractions of X. americana stem barks. This study investigated the anti-inflammatory effect of polysaccharide fractions and tea prepared from X. americana stem barks in mice models of paw edema and peritonitis induced by zymosan. Tea (50,100, 150 mg/kg; p.o.) and polysaccharide fractions (FI, FII: 1 mg/kg; i.v.), containing carbohydrate (44.8, 25.0, 44.4%) and polyphenols (28.3, 0.78, 1.50%), respectively, were administered 1 h before zymosan (500 mg; s.c. or i.p). FT-IR analysis of the tea showed bands indicating C=O and C-O groups vibration, typical of phenolic compounds. Zymosan-induced paw edema (AUC: 355.0 ± 38.1) was inhibited by the tea by 38% (100 mg/kg) and 36% (150 mg/kg). FI and FII reduced the edema by 47% (933.8 ± 158.1 AUC) and 30% (1263 ± 124.8 AUC), respectively. Zymosan i.p. induced hypernociception (4.7 ± 0.3 g) and increased the peritoneal leukocyte migration (10979 ± 1475 cells/ml). FII increased by 66% the nociceptive threshold (13.87 ±1.59 g) and reduced by 63% leukocyte migration (3993 ± 439.1 cells/ml). FII decreased plasma protein by 64% (92.6 ± 4.5 vs. zymosan: 119.6 ± 5.4 mg/ml) and MDA by 63% (57.5 ± 3.5 vs. zymosan: 88.9 ± 6.3 mg/ml). The tea, containing polysaccharides and polyphenols, and polysaccharide fractions FI/FII of X. americana barks possess antiinflammatory effect in mice models of acute inflammation induced by zymosan.

Wound Healing Activity

Background. Hagenia abyssinica (Bruce) J.F. Gmel (Rosaceae) is distributed in the highlands of Ethiopia. The flowers of Hagenia abyssinica (Bruce) J.F. Gmel are used traditionally to treat wound. However, there was no scientific report on wound healing activity of Hagenia abyssinica (Bruce) J.F. Gmel. Thus, this study was initiated to investigate the wound healing and anti-inflammatory activities of 80% methanol crude extract of flowers of Hagenia abyssinica in mice. Objective. The objective of this study was to evaluate the wound healing and anti-inflammatory activity of 80% methanol crude flower extract of Hagenia abyssinica in mice. Methods. Air-dried flowers of Hagenia abyssinica were grounded and macerated three times successively by 80% methanol. The dried extract was fractionated with chloroform, ethyl acetate, and water. Phytochemical screening tests were performed according to established procedures. The crude extract and solvent fractions were formulated as ointments. Wound healing activity of the crude extract was evaluated using excision and incision wound models, and the wound healing activities of solvent fractions were evaluated by using the excision wound model. The anti-inflammatory activity of the 80% methanol extract of Hagenia abyssinica was evaluated using carrageenan-induced hind paw edema model in mice. Result. The 2000 mg/kg test dose of the 10% (w/w) crude extract ointment was safe in rats. Both the 5% (w/w) and 10% (w/w) crude extract ointment-treated groups showed significant wound contraction starting from the day 4th. Both 5% (w/w) and 10% (w/w) crude extract ointments showed significant (P<0.001) increment of tensile strength compared to the negative control. The 10% (w/w) aqueous and ethyl acetate fraction ointment revealed high (P<0.001) percentage of wound contraction. The 100 mg/kg, 200 mg/kg, and 400 mg/kg oral administration of the crude extract had significant inhibition of the paw edema in mice of carrageenan-induced inflammation. Conclusion. The results of this study evidenced that both 5% w/w and 10% w/w 80% methanol extract ointment of the flowers of Hagenia abyssinica have wound healing and anti-inflammatory effects.
