Abstract



Background: Malassezia is considered as major factor in dandruff of human scalp.


Objective: In order to develop an antimicrobial agent, bamboo oil was extracted by high temperture suction from dried bamboo truk abd then antimicrobial activities against Malassezia are investigated.


Methods: Minimum inhibitory concentration and antimicrobial activity were measured in Malassezia species.


Results:

1. Minimum inhibitory concentration of the Bamboo (Phyllosrachys bambusoides) Essential Oil Malassezia furfur standard, Malassezia furfur patient, Malassezia sympodialis standard, Malassezia sympodialis patient, Malassezia dermatis standard, Malassezia dermatis patient were 10 μl/ml, 5 μl/ml, 5 μl/ml, 10 μl/ml, 5 μl/ml and 10 μl/ml respectively.

2. Minimum inhibitory concentration of the Itraconazole Malassezia furfur standard, Malassezia furfur patient, Malassezia sympodialis standard, Malassezia sympodialis patient, Malassezia dermatis standardntia, Malassezia dermatis patient were 10 μg/ml, 10 μg/ml, 10 μg/ml, 0.1 μg/ml, 1 μg/ml, and 0.01 μg/ml, respectively.

3. Minimum inhibitory concentration of the ketoconazole Malassezia furfur standard, Malassezia furfur patient, Malassezia sympodialis standard, Malassezia sympodialis patient, Malassezia dermatis standard, Malassezia dermatis patient were 0.01 μg/ml, 10 μg/ml, 10 μg/ml, 0.1 μg/ml, 0.01 μg/ml, and 0.01 μg/ml, respectively.

4. Malassezia furfur standard, Malassezia furfur patient, Malassezia sympodialis patient and Malassezia dermatis patient showed the strongest antimicrobial effect on bamboo oil > ketoconazole > itraconazole. 5. Malassezia sympodialis standard, Malassezia sympodialis patient and Malassezia dermatis standard strongest antimicrobial effect on ketoconazole > bamboo oil > itraconazole.


Conclusion: Bamboo oil might be applied as antidandruff treatment modality by its anti-malassezial effect.
