Abstract

(family: Lamiaceae), commonly known as kauri booti, is an important ethnomedicinal plant. The current research was conducted to appraise and compare the antioxidant and antibacterial profiles as well as wound healing potentials of Ajugarin I and extract. Ajugarin I and polyphenols in were enumerated by reversed-phase high-performance liquid chromatography analysis that confirmed significant amounts of Ajugarin I (2.2 ± 0.02 μg/mg DW) and other phenolic compounds (14 out of 17 standards). (374.4 ± 0.20 µg AAE/mg of DW, 201.9 ± 0.20 µg AAE/mg of DW, 87 ± 0.30%) showed a higher antioxidant profile compared to Ajugarin I (221.8 ± 0.50 µg AAE/mg of DW, 51.8 ± 0.40 µg AAE/mg of DW, 27.65 ± 0.80%) with 1.86-, 3.89-, and 3.15-fold greater activity in ferric reducing antioxidant power, total antioxidant capacity, and free radical scavenging assays, respectively. Likewise, showed antibacterial activity against 3/5 strains (MIC 25-200 μg/ml) than Ajugarin I (2/5 strains; MIC 50-200 μg/ml). Hemolytic (<2% hemolysis) and dermal toxicity tests rendered both samples non-toxic. Additionally, (100 ± 2.34% at day 12; 9.33 ± 0.47 days) demonstrated 1.11- and 1.24-fold higher percent wound contraction and epithelization time, respectively, than Ajugarin I (95.6 ± 1.52% at day 12; 11.6 ± 0.47 days) as assessed by an excision wound model in mice. Histopathological examination further reinforced the better wound healing potential of with good epithelization, collagen synthesis, fibroblast proliferation, and revascularization. Briefly, we endorse the significant comparative antioxidant, antibacterial, and wound healing activities of and Ajugarin I and present these as prospective candidates for wound healing drugs.

摘要

(唇形科),俗称贝壳杉布蒂,是一种重要的民族药用植物。当前的研究旨在评估和比较Ajugarin I与提取物的抗氧化和抗菌特性以及伤口愈合潜力。通过反相高效液相色谱分析对Ajugarin I和提取物中的多酚进行了测定,结果证实存在大量的Ajugarin I(2.2±0.02μg/mg干重)和其他酚类化合物(17种标准品中的14种)。提取物(374.4±0.20μg抗坏血酸当量/mg干重、201.9±0.20μg抗坏血酸当量/mg干重、87±0.30%)相比Ajugarin I(221.8±0.50μg抗坏血酸当量/mg干重、51.8±0.40μg抗坏血酸当量/mg干重、27.65±0.80%)显示出更高的抗氧化特性,在铁还原抗氧化能力、总抗氧化能力和自由基清除试验中的活性分别高1.86倍、3.89倍和3.15倍。同样,提取物对3/5株菌株显示出抗菌活性(最低抑菌浓度25 - 200μg/ml),高于Ajugarin I(2/5株菌株;最低抑菌浓度50 - 200μg/ml)。溶血(溶血率<2%)和皮肤毒性试验表明两个样品均无毒。此外,通过小鼠切除伤口模型评估,提取物(第12天为100±2.34%;9.33±0.47天)的伤口收缩百分比和上皮化时间分别比Ajugarin I(第12天为95.6±1.52%;11.6±0.47天)高1.11倍和1.24倍。组织病理学检查进一步证实了提取物具有更好的伤口愈合潜力,表现为良好的上皮化、胶原蛋白合成、成纤维细胞增殖和血管再生。简而言之,我们认可提取物和Ajugarin I具有显著的抗氧化、抗菌和伤口愈合比较活性,并将它们作为伤口愈合药物的潜在候选物。
