3. Results and discussion
In the present study, 19 medicinal plant extracts were
examined for antimicrobial activity against Propionibac-
terium acnes and Staphylococcus epidermidis. The results
showed that 13 extracts could effectively inhibit the growth
of Propionibacterium acnes. Among those, the extracts of
Senna alata, Eupatorium odoratum, Garcinia mangostana,
and Barleria lupulina showed strong inhibitory effects
(zone of inhibition ≥15 mm). Interestingly, Hibiscus sab-
dariffa, Garcinia mangostana, Eupatorium odoratum, and
Senna alata extracts showed promising antibacterial activ-
ities against both Propionibacterium acnes and Staphylo-
coccus epidermidis. The remaining 15 plant extracts had no
detectable activity against Staphylococcus epidermidis.

三.结果与讨论在本研究中，19种药用植物提取物对propionibac抗菌活性研究—抗粉刺和Staphylococcus epidermidis。结果结果表明，13种提取物均能有效抑制生长痤疮丙酸杆菌。其中，提取物Senna alata、飞机草、Garcinia mangostana，和有刺鸭嘴花表现出很强的抑制作用（抑制≥15毫米带）。有趣的是，芙蓉SAB—dariffa、Garcinia mangostana、飞机草、和翅果铁刀木提取物有前途的抗菌活性—对痤疮丙酸杆菌和葡萄球菌—球菌球菌。其余15种植物提取物均无对表皮葡萄球菌的检测活动。
