Phytochemistry Medicinal Plant Applications

Plinia cauliflora (Mart.) Kausel, known in Brazil as jabuticaba or jaboticaba has been used by Brazilian native populations for medicinal purposes, including those related to inflammatory conditions, such as asthma, diarrhea, disorders in female genitourinary tract, and tonsillitis. Inflammation has emerged as a main factor for the oxidative stress, hyperglycemia, and dyslipidemia present in chronic noncommunicable diseases (NCDs). Such disturbances have been a leading cause of death worldwide for decades, despite significant efforts in developing new therapies. Therefore, strengthening the relevance of ethnobotanic approaches, as P. cauliflora has the potential to become a natural, native, and traditional product to prevent and treat inflammation-associated diseases more effectively for more people. Evaluate anti-inflammatory, hypoglycemic, hypolipidemic, and analgesic properties of hydroethanolic extract of P. cauliflora epicarps (PcE). Phytochemical compound from the PcE were identified through HPLC-DAD-ESI-MSn analysis. Antioxidant activity was determined by measuring 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging. The anti-inflammatory potential was investigated by carrageenan-induced paw edema and peritonitis in mice. Analgesic effect was assessed, in mice, though hot plate test and acetic acid-induced abdominal writhing. Antidiabetic and hypolipidemic potential were evaluated using alloxan-induced diabetic mice. Tannins, phenolic acids, and their derivatives were the predominant phytochemicals found. Overall, PcE showed different properties related to the treatment of clinical conditions associated with chronic diseases as a potent antioxidant activity, demonstrating a radical scavenging action similar to gallic acid. PcE oral administration also significantly reduced inflammation induced by paw edema and partially blocked leukocyte migration. Moreover, PcE produced peripheral and central analgesic effects, as evaluated in the writhing model and hot plate tests. Treatment with PcE significantly improved glucose levels and lipid markers in diabetic mice. P. cauliflora fruits are rich sources of secondary metabolites, mainly tannins and phenolic acids with high biological potential, which can effectively contribute to the approach of preventing and controlling chronic NCDs.
