mild antimycobacterial activity with the MIC values of 200 and 50 µg/ml, respectively (Yenjai et al., 2004). The volatile oil from K. parviflora has been reported to show antibacterial activity against S. aureus and Pseudomonas aeruginosa (Tanasiriwattana et al., 1997).
Among the isolated compounds, compound 6 (3, 5, 7-trimethoxyflavone) showed appreciable anti-fungal activity with MIC values of 250 µg/ml against the three dermatophytes mentioned above, whereas other compounds had no activity at the highest concentration tested (MIC > 250 µg/ml) (Table 2). According to the obtained results, compound 6could be responsible only in part of the anti-fungal activity.The results indicate that the crude extract of K. parviflorashowed higher antidermatophytic activity than the pure com-pounds. This behavior should be associated with a possiblesynergistic action of the compounds isolated from this plant.These findings support the traditional use of K. parviflorarhizomes for the treatment of dermatophyte infections.
