Bouvardia ternifolia has been used medicinally to treat inflammation. In the present study, we investigate the anti-Alzheimer’s potential effect of the hydroalcoholic extract of B. ternifolia through evaluation of anti-inflammatory and antioxidant activities, quantification of the percentage inhibition of acetylcholinesterase activity, protection effect against b-amyloid fibrillar-induce neurotoxicity, and the identification of the main constituents. Our results show that B. ternifolia extract and ethyl acetate fraction induced anti-inflammatory effects by reducing inflammation by [70 %, while antioxidant test revealed significant IC50 values for flavonoid content fraction (30.67 ± 2.09 lg/ml) and ethyl acetate fraction (42.66 ± 0.93 lg/ml). The maximum inhibition of acetylcholinesterase was exhibited by scopoletin content fraction (38.43 ± 3.94 %), while ethyl acetate fraction exerted neuroprotective effect against b-amyloid peptide (83.97 ± 5.03 %). Phytochemical analysis, showed the presence of 3-O-quercetin glucopyranoside (415 mg/g), rutin (229.9 mg/g), ursolic and oleanolic acid (54 and 20.8 mg/g respectively), 3-O-quercetin rhamnopyranoside (12.8 mg/g), chlorogenic acid (9.5 mg/g), and scopoletin (1.38 mg/g). Our findings support the use of B. ternifolia since the extract induced significant neuroprotection against b-amyloid peptide, anti-inflammatory, antioxidant and antiacetylcholinesterase effects that could be attributed to its contents of polyphenols, coumarins, and triterpenes, and encourage further studies for development of this extract as therapeutic agent in treatment of Alzheimer’s disease.

Systemic arterial hypertension (SAH) is a health problem of great importance worldwide, and endothelial dysfunction underlies SAH development. This condition's main characteristics include vasoconstriction, inflammation, oxidative stress, and procoagulant and proliferative states. This study's objective was to evaluate the antihypertensive, anti-inflammatory, and antioxidant effects of the whole extract and fractions of Agave tequilana in a murine model of SAH. SAH was induced in male ICR or CD-1 (Strain obtained from animals from Charles River Laboratories, Massachusetts) mice by intraperitoneal administration of angiotensin II (AGII) (0.1 μg/kg) for 4 weeks, and then A. tequilana treatments were co-administered with AGII. At the end of the experiment, systolic and diastolic blood pressure were measured and the kidneys were dissected to quantify interleukin (IL)-1β, IL-6, tumor necrosis factor-alpha, IL-10, and malondialdehyde (MDA). The whole extract and the fractions of A. tequilana were chemically characterized using gas chromatography-mass spectrometry. The results indicate that the whole extract (At-W) and At-AcOEt fraction treatment are the most efficient in lowering blood pressure, although all the treatments had an immunomodulatory effect on the cytokines evaluated and an antioxidant effect on lipid peroxidation. Finally, the chromatographic profile shows that the integral extract and fractions of A. tequilana contained phytol (M)3,7,11,15-Tetramethyl-2-hexadecen-1-ol; 9,12-octadecadienoic acid; hentriacontane; 9,19-cyclolanost-24-en-3-ol,(3b); t-sitosterol; and stigmasta-3,5-dien-7-one.
