The dry leaves of Peumus boldus (Monimiaceae) are used in infusion or decoction as a digestive and to improve hepatic complains. Preliminary assays showed free-radical scavenging activity in hot water extracts of boldo leaves, measured by the decoloration of a methanolic solution of the
This work aimed to study the inhibition on acetylcholinesterase activity (AChE), the antioxidant activity and the toxicity towards Caco-2 and HeLa cells of aqueous extracts of Peumus Boldus. An IC(50) value of 0.93 mg/mL, for AChE inhibition, and EC(50) of 18.7 μg/mL, for the antioxidant activity,
Peumus boldus Mol. ("Boldo") and Cryptocarya alba Mol. Looser ("Peumo") are medicinal shrubs with wide geographical distribution in South America. Their leaves and fruits are commonly used in traditional medicine because they exhibit natural medicinal properties for treatment of liver disorders and
Vegetal extracts are widely used as primary ingredients for various products from creams to perfumes in the pharmaceutical, nutraceutic and cosmetic industries. Having concentrated and active extract is essential, as the process must extract as much soluble material as possible in a minimum time,
Peumus boldus Molina (Monimiaceae), commonly referred to as 'boldo', is used in traditional Chilean medicine to treat hepatic and gastrointestinal diseases. Its leaves are rich in antioxidant compounds, principally alkaloids and flavonoids. This study evaluates the protective effect of a complete
The cellular, intracellular and molecular mechanism(s) underlying the toxicity of Mn are still incompletely understood, although several points concerning Mn neurotoxicity have been addressed. Importantly, oxidative changes have been reported to be involved in Mn-induced toxicity. As a consequence,
A very simple and direct method was developed for the qualitative analysis of polyphenols in boldo (Peumus boldus Mol., Monimiaceae) leaves infusions by high-performance liquid chromatography with diode array detection (HPLC-DAD) and electrospray ionization tandem mass spectrometry (HPLC-MS(n)). The
Peumus boldus (P. boldus) is a medicinal plant popularly used in the treatment of gastrointestinal disorders. P. boldus aqueous extract is rich in phenolic compounds and alkaloids that possess antiinflammatory and antioxidant effects. In the present study, the potential protective effect of P.
Currently, the treatment of infectious diseases has not always been successful due to the emergence of microbial resistance worldwide.This study aimed to evaluate the antioxidant activity, content of total phenolic compounds and flavonoids, antifungal OBJECTIVE
Use of cisplatin, a conventional anticancer drug, is restricted because it generates strong hepatotoxicity by accumulating in liver. Therefore its anticancer potential can only be fully exploited if its own toxicity is considerably reduced. Towards this goal, ethanolic extract of the
Tannase (tannin acyl hydrolase, E.C. 3.1.1.20) is an enzyme that catalyzes the hydrolysis of ester and depside linkages in hydrolysable tannins such as tannic acid, releasing gallic acid and glucose. It has several commercial applications in food industry, among which are gallic acid production,
