Evaluation of the anti-inflammatory activities of Quillaja saponaria Mol. saponin extract in mice.

Abstract
OBJECTIVE
Quillaja saponaria bark contains a high percentage of triterpene saponins and has been used for centuries as antiinflammatory and analgesic agent in Chilean folk medicine. In the Present study the anti-inflammatory activities of the aqueous extract of commercially partially purified saponin from Quillaja saponaria Mol. in in vivo animal models.
METHODS
Aqueous extract of the plant material was prepared by cold maceration. The anti-inflammatory activity of a commercial Quillaja saponaria Mol. (QS) saponin extract was investigated by carragenan induced mice paw edema model for acute inflammation (Winter, 1962) [16].
RESULTS
The anti-inflammatory activity was evaluated by carragenan in paw edema model in swiss albino mice (18-20 g). The anti-inflammatory activity was found to be dose dependent in carragenan induced paw edema. QS was found to significantly (p < 0.05) reduce the carragenan induced mice paw edema (38.59%; 20 mg/kg bw) as compared to carragenan control. The percentage inhibition of standard anti-inflammatory drug indomethacin was (55%; 10 mg/kg, bw).
CONCLUSIONS
The results of the present study demonstrate that the aqueous extract of Quillaja saponaria saponins (QS) possess significant anti-inflammatory activity.
