Antioxidant, antihypertensive, anti-hyperglycemic, and antimicrobial activity of aqueous extracts from twelve native plants of the Yucatan coast

Abstract

Looking for a biotechnical potential, aqueous extracts of leaves of 12 native species used in the Mayan traditional medicine of the coastal dune and mangrove of Yucatan (Mexico) were selected to evaluate their biological activities. Rhizophora mangle and Manilkara zapota showed the highest free radical scavenging activity (3.94 ± 0.19 and 6.42 ± 0.32 μg/mL, respectively), and the highest antihypertensive activity was obtained from Solanum donianum (0.38 μg/mL). The anti-hyperglycemic activity of these species was also tested; the highest activities were registered with R . mangle . The antimicrobial activity of Malvaviscus arboreus , S . donianum , M . zapota , and R . mangle at 10% (w/v) was positive against six human pathogenic bacteria and Bonellia macrocarpa against one pathogenic fungus. Solanum donianum , M . zapota , B . macrocarpa , and R . mangle were positive against two pathogenic plant fungi. These results show that the aqueous extracts of five native plants of the Yucatan coast have potential as antioxidants, ACE inhibitors, α-amylase and α-glucosidase inhibitors, and as antimicrobials, which make their exploration for utilization in the agricultural and pharmaceutical industries a possibility.

Metabolic Profiling of Vasorelaxant Extract from Malvaviscus arboreus by LC/QTOF‐MS

“…Previous reports regarding biological activity of secondary metabolites from M. arboreus have showed a variety of biological effects. For instance, there are studies where volatile compounds exhibited moderate antifungal activity, [15] phenolic compounds showed antioxidant capacity, [16,17] and antimicrobial activity [18,19] . Also, further studies have showed identification of kaempferol, cyanidin and pelargonidin [20] .…”

Phytochemical and Pharmacological Evaluation of Ethanol Leaves Extract of Hydnocarpus kurzii (King) Warb

“…Previous studies have demonstrated that several compounds such as gallic acid, palmitic acid, myristic acid, linoleic acid and other phytochemical groups like flavonoids, saponins, volatile oils, sterols, glycosides or organic acids are responsible for diuretic effect. 27,28 Parasitic worms, also known as helminths, can be found in the intestine of human and other vertebrates where they cause diseases by secreting toxins and stealing vital nutrients from host bodies.…”

Nutritional, antioxidant, angiotensin-converting-enzyme and carbohydrate-hydrolyzing-enzyme inhibitory activities of underutilized leafy vegetable: African wild lettuce (Lactuca taraxacifolia Willd)

“…This finding was in line with the reports of Aluko [78], who reported that bioactive proteins exhibited strong inhibitory activities on ACE, which is responsible for the conversion of angiotensin I into angiotensin II. Also, studies have shown that bioactive phytochemicals such as flavonoid and saponin have inhibitory activities on angiotensin converting enzyme, hence, usually used as antihypertensive agents [79,80].…”
