การยับยั้งเชื้อ STAPHYLOCOCCUS AUREUS บนผ้าฝ้ายที่ย้อมด้วยสารสกัดจากฝาง

บทคัดย่อ

A study of an inhibition of Staphylococcus aureus by using three treatments of Caesalpinia sappan L. extracts, extracted by 95% ethanol, was conducted by the disc diffusion method. In addition, the inhibition was examined on cotton jersey fabric (50 mm diameter) dyed with three different treatments of C. sappan extracts, which was modified from the standard test method of AATCC TM 147-2011 Antibacterial Activity Assessment of Textile Materials: Parallel Streak Method. The results of the disc diffusion method showed that the average diameter of the inhibition zone of Treatment 1, Treatment 2, and Treatment 3 was 6.50±0.00 mm, 7.20±0.03 mm, and 9.70±0.06 mm, respectively. Furthermore, the results of inhibition of S. aureus on cotton jersey fabric dyed with C. sappan extracts showed that the average diameter of the inhibition zone of Treatment 1, Treatment 2, and Treatment 3 was 56.50±0.06 mm, 60.60±0.14 mm, and 64.13±0.14 mm, respectively. These results showed that the C. sappan extracts and cotton discs dyed with C. sappan extracts of the three treatments effectively inhibited S. aureus growth, where C. sappan extracts of a Treatment 3 were the most effective in inhibiting S. aureus growth on statistical significance (p≤0.05).
