RESUMO

Peptic ulcer is a universal condition that is a public health problem due to its prevalence, risk of complications and socioeconomic impact. This study aimed to determine the antiulcer effect of the hydroalcoholic extract from Senna multiglandulosa leaves against ethanol-induced gastric ulcer in rats. Thirty-six male albino Holtzman rats were assigned to six groups. Group I received physiological saline (PS) at doses of 10 mL/kg; group II: ethanol (PS + ethanol 5 mL/kg); group III; omeprazole 100 mg/kg/day (gold standard); groups IV, V and VI received doses of 100, 250 and 500 mg/kg/day of S. multiglandulosa extract, respectively. The stomach was removed to determine the ulcerative lesions and two sections of the glandular zone to carry out the analysis of the gastric mucus and sulfhydryl groups content. As result, S. multiglandulosa at doses of 250 and 500 mg/kg produced a significant decrease of the injured area, with values of 46.28 ± 7.95 mm2 and 6.91 ± 2.48 mm2, respectively (P < 0.001). The protective effect was showed at dose of 500 mg/kg (92.27%) and a significant increase in the production of mucus with a value of 83.13 ± 13.09 mg/mL/g of tissue (61.14%). The production of nonprotein sulfhydryl groups (NP-SG) also increased significantly at the three evaluated doses, being 250.34 ± 21.16 µg/g tissue at dose of 500 mg/kg (119.94%). It is concluded that S. multiglandulosa extract protected against ethanol-induced gastric ulcer due to increased gastric mucus secretion and its antioxidant activity due to the generation of nonprotein sulfhydryl groups.

RESUMO

Medicinal plants are being used worldwide for centuries for their beneficial properties. Some of the most popular medicinal plants belong to the Melissa genus, and different health beneficial effects have already been identified for this genus. Among these species, in particular, the Melissa officinalis L. has been reported as having many biological activities, such as antioxidant, antimicrobial, antitumour, antiviral, antiallergic, anti-inflammatory, and also flatulence inhibiting effects. The beneficial properties of the Melissa officinalis, also known as "lemon balm herb", can be related to the bioactive compounds such as terpenoids, alcohols, rosmarinic acid, and phenolic antioxidants which are present in the plant. In this updated review, the botanical, geographical, nutritional, phytochemical, and traditional medical aspects of M. officinalis have been considered as well as in vitro and in vivo and clinically proven therapeutic properties have been reviewed with a special focus on health-promoting effects and possible perspective nutraceutical applications. To evidence the relevance of this plant in the research and completely assess the context, a literature quantitative research analysis has been performed indicating the great interest towards this plant for its beneficial properties.
