In this study we evaluated the composition of the crude extract and fractions of Tabernaemontana catharinensis (Apocynaceae) by HPLC/DAD and GC/MS. We also tested the antioxidant capacity and investigated the contents of polyphenols, flavonoids, tannins and alkaloids of T. catharinensis stem bark.
The present study was conducted to evaluate the antiulcerogenic effect and recognize the basic mechanism of action of Tabernaemontana divaricata (L.) R. Br. flowers. T. divaricata flower methanolic extract (TDFME) was screened for antiulcer activity versus aspirin and ethanol induced gastric ulcers
In the present work the antioxidant and antimycobacterial activities were determined for extracts from Tabernaemontana catharinensis. The extracts' global yields were obtained using supercritical CO2 plus cosolvent. The cosolvents ethanol, isopropyl alcohol, methanol, and water and their mixtures
OBJECTIVE
The goal of this study was to evaluate the antioxidant and antiproliferative activities of 10 traditional medicinal plants, Asclepias curassavica, Ophiorrhiza mungos Linn., Cynodon dactylon (L.) Pers, Costus speciosus (J. Koenig.) Smith Costaceae, Achyranthes aspera L., Amaranthus tristis
Ethanolic extracts from 15 plant species, representing eight different families, used in traditional medicine in Ecuador were evaluated for antiinflammatory and antioxidant activities. Conyza floribunda, Eupatorium articulatum, Bonafousia longituba, Bonafousia sananho, Tagetes pusilla and Piper
Ethnopharmacological knowledge is important for the identification of active compounds from natural products. Pain may have different aetiologies with complex mechanisms. Tabernaemontana catharinensis A. DC. is well known for indole alkaloids, being used empirically in folk medicine, In the present study, the flavonoid fraction of Tabernaemontana divaricata flavonoid fraction(TdFf) leaves was investigated for its in vitro and in vivo antioxidative and antitumor activity.The flavonoid fraction of ethyl acetate extract was assessed for The essential oils obtained by hydrodistillation from the leaves of Tabernaemontana catharinensis had their composition analysed by GC-MS. A total of 18 substances were identified, consisting of a complex mixture of sesquiterpenes (83.52%), monoterpenes (5.46%) and triterpenes (4.56%). The main
The antioxidant capacity of the crude extract and fractions of Tabernaemontana catharinensis fruits and branches, was evaluated by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method and the content of polyphenols, flavonoids, alkaloids and condensed tannins were determined by the spectrophotometric
Silver nanoparticles (AgNPs) have been found useful in biological systems and in medicine since they possess a large surface area to volume ratio, which confers on them several unique properties. In the present study, AgNPs that had been biosynthesized using an ethanolic extract of Tabernaemontana
The present work aimed to analyze the alkaloid content of the ethanolic extract of Tabernaemontana catharinensis (Apocynaceae family) and its fractions as well as to evaluate their antioxidant and anticholinesterasic activities. The analyses of the ethanolic extract of T. catharinensis by mass
Flavonoids are exploited as antioxidants, antimicrobial, antithrombogenic, antiviral, and antihypercholesterolemic agents. Normally, conventional extraction techniques like soxhlet or shake flask methods provide low yield of flavonoids with structural loss, and thereby, these techniques may be
OBJECTIVE
Tabernaemontana divaricata (TD) from Apocynaceae family offers the traditional folklore medicinal benefits such as an anti-epileptic, anti-mania, brain tonic, and anti-oxidant. The aim of the present study was to evaluate the effect of ethanolic extract of TD leaves on burying behavior in
Tabernaemontana divaricata a common garden plant in tropical countries has been used as a traditional medicine. However, no recent review articles of T. divaricata, particularly discussing its pharmacological properties, are available. This review presents the ethnobotany and ethnopharmacology of T.
The aim of this study was to evaluate the most effective extraction condition (temperature, solvent type and time) for recovery of high-value phytochemicals present in the Tabernaemontana catharinensis leaves (TC) and to assess their effect on biochemical parameters in streptozotocin-induced
