The study evaluated the phytochemicals, acute toxicity, antioxidant, anti-inflammatory and antimalarial activities of B. vulgaris extract. The antioxidant potential was examined using 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay and the formalin-induced inflammation technique was used to evaluate the anti-inflammatory activity. Also, the in vivo antimalarial activity was evaluated against Plasmodium berghei parasites and the required doses were given according to the weight of the animal two hours after inoculation of parasites on D1, then once daily for D2-D4. Phytochemical analysis showed that Beta vulgaris extract contained alkaloids, terpenoids, tannins, saponins, phenolics, anthraquinones, and flavonoids. The oral administration of crude ethanol extract of B. vulgaris to Swiss mice was not toxic even up to a dose of 5000 mg/kg. The root extract had the highest percentage inhibition of 74.46 ± 0.98 and for ascorbic acid 98.66 ± 0.16 at 1000 µg/mL extract in the antioxidant evaluation. Beta vulgaris had significant anti-inflammatory activity at 50 mg/kg at 1hr being the most effective. There was a dose-dependent increase in percentage chemo-suppression of the parasites by the different groups with maximum effect at 800 mg/kg (59.68-35.09%). This study validates the phytomedicinal use of beet root extract for the management of inflammation, malaria and oxidative stress-related infections.
本研究评价了寻常草提取物的植物化学成分、急性毒性、抗氧化、抗炎和抗疟活性。采用1,1-二苯基-2-苦味酰肼(DPPH)自由基清除法检测其抗氧化能力,采用福尔马林诱导炎症技术评价其抗炎活性。D1接种2 h后根据动物体重给予所需剂量,D2-D4每日1次,测定其对伯氏疟原虫体内抗疟活性。植物化学分析表明,甜菜提取物中含有生物碱、萜类、单宁、皂苷、酚类、蒽醌类和类黄酮。即使给药剂量达到5000mg /kg,也对瑞士小鼠无毒性。在1000µg/mL时,根提取物对抗坏血酸的抑制率最高,为74.46±0.98,对抗坏血酸的抑制率为98.66±0.16。寻常β具有显著的抗炎活性,剂量为50 mg/kg,作用1小时最有效。不同剂量组对寄生虫的化学抑制百分比呈剂量依赖性增加,800 mg/kg时效果最大(59.68 ~ 35.09%)。本研究验证了甜菜根提取物在治疗炎症、疟疾和氧化应激相关感染方面的植物医学用途。
