As part of our continuous effort to find potential anti-inflammatory agents from endophytic fungi, a Fusarium solani strain, isolated from the plant Aponogeton undulatus Roxb., was investigated. Cerevisterol (CRVS) was identified from endophytic fungi, a Fusarium solani strain, and moreover exhibited anti-inflammatory activity. However, the underlying mode of action remains poorly understood. The aim of this study is to reveal the potential mechanisms of CRVS against inflammation on a molecular ...

Adenanthera pavonina L. is an important medicinal plant and its barks are used in traditional medicine for treating different diseases. Therefore, a phytochemical investigation was carried out to isolate and identify secondary metabolites from its barks. Seven compounds namely ethyl 3,3-dimethyl-13-hydroxytridecanoate (1), stigmasta-5,22-dien-3β-ol (2), tert.butyl tridecanoate (3), 6-α-hydroxy stigmast-20(21)-en-3-one (4) of dichloromethane extract and 18-(2′, 3′-dihydroxyphenyl)nonadec-17-en-2-...

Cladosporium species are endophytic fungi that grow on organic matter and are considered food contaminants. The anti-microbial and anti-tumor naphthoquinones fusarubin (FUS) and anhydrofusarubin (AFU) were isolated using column chromatography from a Cladosporium species residing inside Rauwolfia leaves. The impact of FUS and AFU on cell growth was assessed in acute myeloid leukemia (OCI-AML3) and other hematologic tumor cell lines (HL-60, U937, and Jurkat). Treatment with FUS or AFU reduced the ...

Abstract Anethum sowa L. has been used as a spice herb in the Asian and European culinary systems to add flavour and taste. The studied plant has diverse folkloric medicinal value. Present study was designed to isolate phytochemicals from the hexane, chloroform and ethyl acetate extracts of the roots by various chromatographic techniques. Based on spectral analysis (IR, LC–MS, NMR) the isolated compounds were identified as physcione (1), β-sitosterol (2), stigmasterol (3), 2-oxo-3-propyl-2H-chro...

The background of this study was to investigate the antioxidant, cytotoxic, thrombolytic and antimicrobial activity of the petroleum ether (PE), carbon tetrachloride (CTC), chloroform (CF) and aqueous (AQ) soluble fractions of crude methanolic Zanthoxylum rhetsa root bark with two isolated quinolone alkaloids, 8-methoxy-n-methylflindersine (1) and zanthodioline (2). Structures were characterized by 1D NMR analyses. Antioxidant activity was assessed by using DPPH assay and antimicrobial activity ...
Stem bark of Dalbergia lanceolaria was subjected to methanolic extraction and extensive phytochemical separation. The process yielded four known compounds namely Jateorin (1), Columbin (2), β-sitosterol (3), and Lupeol (4). The compounds were identified using nuclear magnetic resonance spectral data namely 1H NMR, 13C NMR, 1H-1H COSY, HMBC, and DEPT-135 and verified by comparing the data with previous literature. All four compounds are being reported for the first time from the species D. lanceo...
