pimenta pseudocaryophyllus/抗氧化剂

Pimenta pseudocaryophyllus is a Brazilian native plant that presents high concentrations of flavonoids and other polyphenolic compounds. Herein, we evaluated: (1) the chemical properties of P. pseudocaryophyllus ethanolic extract (PPE), (2) the in vitro antioxidant activity (AA) of PPE and of two

The ethyl acetate-soluble part of allspice, berries of Pimenta dicica, showed strong antioxidant activity and radical-scavenging activity against 1,1diphenyl-2-picrylhydrazl (DPPH) radical. From the ethyl acetate-soluble part, two new compounds, 5-galloyloxy-3-4-dihydroxypentanoic acid and

Cinnamomum tamala Nees and Eberm (tejpat) and Pimenta dioica (L.) Merr (pimento) leaves are commonly used for flavouring food and widely used in pharmaceutical preparations because of their hypoglycemic, carminative and stimulant properties. In this study, we compared the chemical composition and

The composition and antioxidant activity of the essential oil obtained through hydrodistillation of pimento berry [Pimenta dioica (L.) Merr] samples, namely P1 and P2, sourced from Jamaica, were studied. The chemical composition was analysed by GC and GC-MS methods. The antioxidant activities of the

This paper presents the quantification, antioxidant and antimicrobial activity of capsaicin, dihydrocapsaicin and the flavonoid chrysoeriol isolated from different extracts (hexane and acetonitrile extracts from whole fruit, peel and seed) of Capsicum frutescens (pimenta malagueta). The acetonitrile

Two galloylglucosides, 6-hydroxy-eugenol 4-O-(6'-O-galloyl)-beta-D-4C1-glucopyranoside (4) and 3-(4-hydroxy-3-methoxyphenyl)-propane-1,2-diol-2-O-(2',6'-di-O-galloyl)-beta-D -4C1-glucopyranoside (7), and two C-glycosidic tannins, vascalaginone (10) and grandininol (14), together with fourteen known

Plants rich in antioxidant substances may be a promising strategy for preventing UV-induced oxidative and inflammatory damage of the skin. Pimenta pseudocaryophyllus is native to Brazil and presents flavonoids and other polyphenolic compounds in high concentration. Thus, the present study evaluated

BACKGROUND Pimenta racemosa tree has many traditional uses where its leaves are used as herbal tea for treatment of flatulence, gastric disorder, osteoarthritis, colds and fever in addition to its analgesic and anti-inflammatory activities. So, this study aimed to isolate phenolic constituents of

BACKGROUND Pimenta pseudocaryophyllus (Gomes) Landrum (Myrtaceae) has been traditionally used in Brazilian folk medicine. Studies have established the botanical characterization, phytochemistry profile, and pharmacological potential of this species, including antibiotic, anxiolytic, antidepressant,

Recently, the synthesis of radiolabeled plant origin compounds has been increased due to their high uptake on some cancer cell lines. Eugenol (EUG), a phenolic natural compound in the essential oils of different spices such as Syzygium aromaticum (clove), Pimenta racemosa (bay leaves), and

Background: Pimenta dioica is a native tree of Central America, Southern Mexico, and the Caribbean used in traditional medicine. It grows in wet forests in the Guatemalan departments of Petén and Izabal. Since the plant is not being economically exploited in Guatemala, this study was

In this study, the anti-hyperlipidemic effect of aqueous extract of Pimenta officinalis (APO) was investigated in experimental rats fed with high fat diet (HFD). Hyperlipidemia in experimental rats was evidenced by a significant enhancement in the level of glycerol, triglycerides and phopholipids in
