It has been demonstrated that Lantana camara possesses several therapeutic properties that can be used to treat various human diseases, including dermatological and gastrointestinal conditions, tetanus, malaria, and tumours. In this investigation, every collected part of L. camara was extracted with absolute methanol to examine its antioxidant capacity using the DPPH assay and its anti-leukemia activity on two AML cell lines, MOLM-13 and MV4-11. In addition, anti-inflammatory effectiveness was evaluated. The results show that extracts from various sections of L. camara have a significant ability to neutralize free radicals, as indicated by their EC50 values. Most of the extracts had values less than 100 μg/ml, with the flower extract having an even lower value of less than 50 μg/ml. Experiments on two AML cell lines showed that the anti-leukemia effects of the extracts were remarkable, with the most potent impact belonging to the root extract (IC50 was 9.78 ± 0.61 and 12.48 ± 1.69 for MOLM-13 and MV4-11 cell lines). The antitumor effect of the extracts was determined to be time- and dose-dependent and did not correlate with antioxidant capacity. Furthermore, when BJ cells were exposed to L. camara root and leaf extracts, their migratory potential was dramatically reduced compared to untreated cells. The extracts demonstrated potential anti-inflammatory capabilities by lowering NO production in LPS-induced BJ cells.
已证实马缨丹具有多种治疗特性,可用于治疗各种人类疾病,包括皮肤病和胃肠道疾病、破伤风、疟疾和肿瘤。在这项研究中,用甲醇对马缨丹的每一个采集部位进行提取,并用 DPPH 测定法检测其抗氧化能力和对两种 AML 细胞系(MOLM-13 和 MV4-11)的抗白血病活性。此外,还评估了抗炎效果。结果表明,马缨丹不同部位的提取物具有显著的中和自由基能力,这反映在其 EC50 值上。大多数提取物的 EC50 值小于 100μg/ml,花提取物的值甚至更低,小于 50μg/ml。对两种 AML 细胞系的实验表明,提取物的抗白血病作用显著,其中根提取物的作用最强(对 MOLM-13 和 MV4-11 细胞系的 IC50 值分别为 9.78±0.61 和 12.48±1.69)。提取物的抗肿瘤作用呈时间和剂量依赖性,与抗氧化能力无关。此外,当 BJ 细胞暴露于马缨丹根和叶的提取物时,与未经处理的细胞相比,其迁移能力显著降低。提取物通过降低 LPS 诱导的 BJ 细胞中 NO 的产生显示出潜在的抗炎能力。
