is a plant species belonging to Lauraceae family that is distributed throughout Indonesia, Malaysia, and New Guinea. The seeds have been traditionally used by local people in Kalimantan, Indonesia for the treatment of boils; however, there is no information about the potency of its branch, bark and leaves yet. This study aimed to determine the antioxidant, antimicrobial activity as well as the phytochemical constituent of branch, bark, and leaves. Extraction was performed by successive maceration method using -hexane, ethyl acetate, and ethanol solvent. Antioxidant activity was evaluated by DPPH radical scavenging assay. The antimicrobial activity using the 96 well-plate microdilution broth method against and . Based on the phytochemical analysis, it showed that extract of contains alkaloids, flavonoids, tannins, terpenoids, and coumarin. The results showed that all extracts of plant samples displayed the ability to inhibit DPPH free radical formation and all tested microorganisms. contains secondary metabolites such as alkaloids, flavonoids, tannins, terpenoids, carotenoids, and coumarin. The antioxidant activity on different plant extracts was a range as very strong to weak capacity. All extracts in this study could inhibit the growth of and .
是一种属于樟科的植物物种,分布于印度尼西亚、马来西亚和新几内亚。其种子在印度尼西亚加里曼丹的当地人传统上用于治疗疖子;然而,关于其树枝、树皮和树叶的功效尚无信息。本研究旨在确定树枝、树皮和树叶的抗氧化、抗菌活性以及植物化学成分。采用连续浸渍法,使用正己烷、乙酸乙酯和乙醇溶剂进行提取。通过DPPH自由基清除试验评估抗氧化活性。采用96孔板微量稀释肉汤法对[具体微生物名称1]和[具体微生物名称2]进行抗菌活性测试。基于植物化学分析,结果表明[植物名称]提取物含有生物碱、黄酮类化合物、单宁、萜类化合物和香豆素。结果表明,植物样品的所有提取物均具有抑制DPPH自由基形成的能力以及对所有测试微生物的抑制能力。[植物名称]含有生物碱、黄酮类化合物、单宁、萜类化合物、类胡萝卜素和香豆素等次生代谢产物。不同植物提取物的抗氧化活性范围为极强到弱。本研究中的所有提取物均可抑制[具体微生物名称1]和[具体微生物名称2]的生长。
