Abstract

Lam, commonly known as moringa, is a plant widely used both as a human food and for medicinal purposes around the world. This research aimed to evaluate the efficacy of the aqueous extract of leaves (MoAE) and benzyl isothiocyanate (BIT) in rats with induced breast cancer. Cancer was induced with 7,12-dimethylbenz[a]anthracene (DMBA) at a dose of 60 mg/kg by orogastric gavage once only. Forty-eight rats were randomly assigned to eight groups, each consisting of six individuals. The control group (healthy) was called Group I. Group II received DMBA plus saline. In addition to DMBA, Groups III, IV, and V received MoAE at 100, 250, and 500 mg/kg/day, respectively, while Groups VI, VII, and VIII received BIT at 5, 10, and 20 mg/kg/day, respectively. Treatment was carried out for 13 weeks. Secondary metabolite analysis results identified predominantly quercetin, caffeoylquinic acid, neochlorogenic acid, vitexin, and kaempferol, as well as tropone, betaine, loliolide, and vitexin. The administration of MoAE at a dose of 500 mg/kg and BIT at 20 mg/kg exhibited a notable decrease in both the total tumor count and the cumulative tumor weight, along with a delay in their onset. Furthermore, they improved the histological grade. A significant decrease in serum levels of VEGF and IL-1β levels was observed ( < 0.001) with a better effect demonstrated with MoAE at 500 mg/kg and BIT at 20 mg/kg. In conclusion, this study suggests that both the aqueous extract of leaves and the benzyl isothiocyanate possess antitumor properties against mammary carcinogenesis, and this effect could be due, at least in part, to the flavonoids and isothiocyanates present in the extract.

摘要

菜,俗称辣木,是一种在世界各地被广泛用作人类食物和药用的植物。本研究旨在评估叶水提物(MoAE)和苄基异硫氰酸酯(BIT)在诱导乳腺癌大鼠中的疗效。采用 7,12-二甲基苯并[a]蒽(DMBA)60mg/kg 灌胃一次性诱导癌症。48 只大鼠随机分为 8 组,每组 6 只。对照组(健康)称为第 I 组。第 II 组给予 DMBA 加生理盐水。除 DMBA 外,第 III、IV 和 V 组分别给予 MoAE 100、250 和 500mg/kg/天,第 VI、VII 和 VIII 组分别给予 BIT 5、10 和 20mg/kg/天。治疗进行了 13 周。次生代谢物分析结果表明,主要含有槲皮素、咖啡酰奎宁酸、新绿原酸、牡荆素和山奈酚,以及托烷、甜菜碱、千里光内酯和牡荆素。MoAE 剂量为 500mg/kg,BIT 剂量为 20mg/kg 时,总肿瘤数和累积肿瘤重量明显减少,发病时间延迟。此外,它们改善了组织学分级。血清 VEGF 和 IL-1β 水平显著降低(<0.001),MoAE 500mg/kg 和 BIT 20mg/kg 效果更好。综上所述,本研究表明,叶水提物和苄基异硫氰酸酯均具有抗乳腺癌发生的抗肿瘤特性,这种作用至少部分归因于提取物中的类黄酮和异硫氰酸盐。
