Preliminary antibacterial screening of local crude drugs was carried out using the cariogenic bacterium, Streptococcus mutans. Of 79 aqueous extracts tested, 6 crude drugs were shown to have significant antibacterial activity with minimal inhibitory concentration equal to or lower than 7.8 mg/ml
Silver nanoparticles contribute a giant share to the realm of modern nanobiotechnology. Their utility as antimicrobial agents is also well documented. Green synthesis of nanoparticle has several advantages over its chemical synthesis. In the present study, Thuja occidentalis leaf extract mediated
Hydrophilic knotwood extracts from 18 wood species were assessed in disc diffusion and liquid culture tests for antibacterial effects against three species of paper mill bacteria. The Pinus sylvestris, P. resinosa, P. contorta, and P. banksiana extracts decreased or inhibited bacterial growth. The
Recent research has shown the bioprospecting of endophytic fungi from Cupressaceae. Here, we further uncover that the healthy cypress plants such as Cupressus arizonica, Cupressus sempervirens var. cereiformis, and Thuja orientalis host highly bioactive endophytic Alternaria fungal species. Indeed,
Poly(ethylene glycol) stabilized colloidal silver nanoparticles were prepared using the reductive potency of the aqueous extract of Thuja occidentalis leaves under ambient conditions. The nanoparticles were well dispersed within a narrow size spectrum (7-14 nm) and displayed characteristic surface
Six essential oils (from oregano, thyme, clove, lavender, clary sage, and arborvitae) exhibited different antibacterial and antifungal properties. Antimicrobial activity was shown against pathogenic (Escherichia coli, Salmonella typhimurium, Yersinia enterocolitica, Staphylococcus aureus, Listeria
The present research was carried out at the Institute of Biotechnology and Genetic Engineering, The University of Agriculture Peshawar, KPK Pakistan. In this study crude methanolic extracts from Thuja occidentalis were tested for their antimicrobial activity against five different bacterial strains
Beta-thujaplicin (hinokitiol) is a tropolone-related compound purified from the wood of Chamaecyparis obtusa, SIEB: et Zucc. and Thuja plicata D. Don. All Staphylococcus aureus isolates were inhibited by beta-thujaplicin with MICs of 1.56-3.13 mg/L. However, a paradoxical zone phenomenon occurred,
Eight new sesquiterpenes with diverse skeletons involving four cuparenes, denominated thujasutchins F-I (1-4), one eudesmane and one cedrol, named thujasutchin J (5) and thujasutchin K (6), as well as two thujopsenes thujasutchins L-M (7-8) together with three known congener compounds (9-11) were
In this study, we determined the antimicrobial activity of ten essential oils (EOs)-oregano, thyme, clove, arborvitae, cassia, lemongrass, melaleuca, eucalyptus, lavender, and clary sage-against drug-resistant microorganisms previously isolated from patients with skin infections. The essential oil
Aspergilli are filamentous, cosmopolitan and ubiquitous fungi which have significant impact on human, animal and plant welfare worldwide. Due to their extraordinary metabolic diversity, Aspergillus species are used in biotechnology for the production of a vast array of biomolecules. However, little
