Abstract

The leaves of Erythrina has been used in Indonesia as a remedy for rheumatism, stomach-ache, asthma, dysentery, contact dermatitis, eczema and skin infections. However, there have been limited phytochemical or biological studies on the leaves of E. subumbrans and there are not studies that align with its traditional medicinal uses. The aim of this study was to assess the antimicrobial activity of the leaves of E. subumbrans to support its topical use in the treatment of skin infections. Disc diffusion agar assays were used to determine the antimicrobial activities of ethanol extracts of the leaves of E. subumbrans.The ethanol extracts showed the most significant activity with MIC values of 0,5 µg/mL. against a sensitive strain of Staphylococcus epidermidis. Extract concentration of 0,5 mg/ml, 1 mg/ml, 5 mg/ml and 10 mg/ml showed inhibition zone continuously as high as 1,83 mm; 3,42 mm; 5,17 mm, and 8,00 mm. The ethanol extracts of the leaves of E. subumbrans also showed significant activity against Candida albicans with MIC values of 0,5 µg/mL. Extract concentration of 0,5 mg/ml, 1 mg/ml, 5 mg/ml and 10 mg/ml showed inhibition zone continuously as high as 4,00 mm; 4,17 mm; 5,25 mm, and 6,50 mm. Bioactive substance test showed that alkaloid, flavonoid, saponin, and triterpenoid were found in E. subumbrans extract indicates potential activity as antimicrobial agent. These results provide support for the customary (traditional and contemporary) use of E.subumbrans leaves for the treatment of nosocomial infections.

大黄菌的抑菌活性研究稳定)。叶萃取精华
在印度尼西亚,赤藓的叶子被用来治疗风湿病、胃痛、哮喘、痢疾、接触性皮炎、湿疹和皮肤感染。然而,对野蕨叶的植物化学或生物学研究有限,并且没有与其传统药用用途相一致的研究。本研究的目的是评估的抗菌活性,以支持其在治疗皮肤感染局部使用。采用圆盘扩散琼脂法测定了野牡丹叶乙醇提取物的抑菌活性。乙醇提取物的MIC值为0.5µg/mL时,活性最显著。抵抗一种表皮葡萄球菌敏感菌株。0、5 mg/ml、1 mg/ml、5 mg/ml、10 mg/ml提取液浓度连续出现高达1、83 mm的抑制带;3, 42毫米;5毫米,17毫米和8000毫米。山竹叶乙醇提取物对白色念珠菌的抑制作用也很显著,MIC值为0.5µg/mL。0、5 mg/ml、1 mg/ml、5 mg/ml、10 mg/ml提取液的抑菌带连续高至4 000 mm;4、17毫米;5,25毫米和6,50毫米。生物活性物质试验表明,黄芪提取物中含有生物碱、类黄酮、皂苷和三萜,具有潜在的抗菌活性。这些结果为传统的(传统的和现代的)使用麻叶治疗医院感染提供了支持。
