Total Oil

The chemical composition of the oil of Chamaecyparis nootkatensis (D. Don) Spach. has been analysed by gas chromatography (GC) and gas chromatography coupled to mass spectrometry (GCMS). A total of 34 compounds were identified representing more than 90% of the total oil. The oil was richer in monoterpenes than in sesquiterpenes, the major constituents being limonene (53.2%), δ-3-carene (21.0%) and α-pinene (12.2%). The antibacterial and antifungal activities of the oil were also tested against Candida albicans, Bacillus subtilis, Enterobacter aerogenes, Enterococcus faecalis, Escherichia coli, Micrococcus luteus, Pseudomonas aeruginosa, Salmonella sp. and Serratia marcescens. Only two of these, Bacillus subtilis and Candida albicans, were sensitive to the treatment, inhibition zones of 11 and 14 mm diameter being obtained, respectively. As far as we know, this is the first report of the antifungal and antibacterial activity of this species.

Antibacterial Potential

Two new ellagic acid derivatives, named panconosides A (1) andB(2) were isolated from Pancovia pedicellaris together with eleven known compounds (3 - 13). The structures of 1 and 2, as well as those of the known compounds were established by spectroscopic methods and by comparison with previously reported data. Compounds 1 and 2 were tested in vitro for their antibacterial potential against six strains of microorganisms: Micrococcus luteus, Streptococcus ferus, Streptococcus minor, Escherichia coli, Bacillus subtilis, and Pseudomonas agarici. They were found to exhibit moderate antibacterial activity against all the tested strains compared to standard drugs.

ɑ-Mangostin (1), β-mangostin (2) and gartanin (3) have been isolated from the trunk latex of Garcinia mangostana Linn. and investigated for their antimicrobial activities against Bacillus subtilis, Enterococcus faecalis, Micrococcus luteus, Salmonella typhosa, Staphylococcus epidermidis, Streptococcus mutans and Vibrio cholerae. The significant antibacterial activity showed by α-mangostin (1) against Bacillus subtilis, Enterococcus faecalis. Staphylococcus epidermidis and Vibrio cholerae, but all compounds showed no activity to inhibit the growth of Micrococcus luteus and Streptococcus mutans.

Two ether and one ester derivatives of the 4-nitro-3-hydroxybenzoic acid were synthesized and characterized. The in vitro antimicrobial and cytotoxic activities of the three novel compounds were also evaluated. The aromatic derivatives showed antibacterial activity against one of the four microorganisms tested and two compounds (C8 and NOBA) had a lower IC50 in HeLa cells.
