BACKGROUND
Calophyllum inophyllum L. (Calophyllaceae) is an evergreen tree ethno-medically used along the seashores and islands of the Indian and Pacific Oceans, especially in Polynesia. Oil extracted from the seeds is traditionally used topically to treat a wide range of skin injuries from burn,
Six novel chromanone acids (1-6) were isolated from the bark of Calophyllum brasiliense Cambess. Their structures were elucidated on the basis of 1D and 2D NMR experiments, as well as mass spectrometry. All compounds showed moderate to strong antibacterial activity against Bacillus cereus and
Caseinate-stabilized emulsions of black cumin (Nigella sativa) and tamanu (Calophyllum inophyllum) oils were studied in terms of preparation, characterization, and antibacterial properties. The oils were described while using their basic characteristics, including fatty acid
Thirty-two extracts from 22 Mexican medicinal plants of 15 different families were assayed to determine their antibacterial activity against Escherichia coli and Staphylococcus aureus. Seventeen plants showed antibacterial activity, while five plants showed no activity against both bacteria. All of
Calozeyloxanthone ( 1) was re-isolated from the root bark of Calophyllum moonii, an endemic species of Sri Lanka, and found to be active against vancomycin-resistant Enterococci (VRE) and vancomycin-sensitive Enterococci (VSE) with MIC values of 6.25 microg/ml and 12.5 microg/ml, respectively.
A phytochemical study carried out on the plant, Calophyllum wallichianum has led to the isolation of a new coumarin, wallimarin T (1) and a known coumarin, calanolide E (2) along with two common triterpenes, friedelin (3) and stigmasterol (4). The structures of these compounds were elucidated with
Calophyllum apetalum and Garcinia morella, medicinal plants are endemic to Western Ghats, Karnataka, India. Sixteen Myrothecium isolates were obtained from the tissues of bark and twigs of these plants. The purpose of this study was to explore the antimicrobial activity and genetic variability of
The methanol extracts of leaves, root and stem barks of Calophyllum soulattri were partitioned with petrol, dichloromethane, ethyl acetate. The extracts demonstrated a range of antibacterial activity, improved on fractionation. None were found to be active against the moulds.
Calophyllum brasiliense (Clusiaceae) is a tree that grows mainly in the Atlantic Forest in Brazil. Its leaves possess antibacterial activity, cytotoxic activity against certain tumor cell lines, and antimicrobial activity in BALB/c mice infected with Leishmania (Leishmania) amazonensis.Aiming to
Jacareubin is a xanthone isolated from the heartwood of Calophyllum brasiliense with antibacterial and gastroprotective properties and the intention for clinical use as an anti-cancer treatment (due to the similar chemical structure to other anti-neoplastic drugs) requires an investigation of
BACKGROUND
Endophytes colonizing medicinal plants are diverse, constituting a rich bioresource for novel natural products.
OBJECTIVE
Myrothecium sp. isolate M1-CA-102 was the most promising among the 16 Myrothecium isolates screened. The bioactive potential of the crude extract from the Calophyllum
The study of the chemical constituents of the root bark and the nut of Calophyllum inophyllum has resulted in the isolation and characterization of a xanthone derivative, named inoxanthone, 3, together with 12 known compounds: caloxanthones A, 4 and B, 5, macluraxanthone, 6, 1,5-dihydroxyxanthone,
Calophyllum plants have great pharmaceutical value. Some species of this genus are used in folk medicine to treat and cure diseases, such as toothache, rheumatism, diarrhea, chronic ulcers, skin infections, and wounds. The genus is known to be rich in chromanone derivatives, and some of these
