“…13,14 H. pectinata essential oil was tested at concentrations ranging from 0.5 to 300 mg mL -1 (diluted in 0.5% DMSO according to CLSI M7-A6 15 and M27-A2 16 ). Each well contained 100 μL of twofold serially diluted essential oil, 95 μL of double strength BHI growth medium (bacteria) or RPMI 1640 (yeasts), and 0.5 μL of an overnight culture of each strain, representing, approximately, 5 x 10 4 bacterial cells mL -1 and 2.5 x 10 3 yeast cells mL -1 .…”

ChemiCal Composition and antimiCrobial aCtivity of the essential oil ofEssential oil was extracted from leaves of Hyptis pectinata using hydrodistillation, and its composition determined using GC-FID and GC-MS. Chemical analysis showed that there was a predominance of sesquiterpenes, of which b-caryophyllene (18.34%), caryophyllene oxide (18.00%) and calamusenone (24.68%) were measured for the first time in the genus Hyptis. Twenty-one compounds were identified, and calamusenone was isolated using preparative thin layer chromatography with a silica gel plate (60 PF 254 ). The minimal inhibitory concentration (MIC) and minimal microbicidal concentration (MMC) were determined for various pathogenic microorganisms. H. pectinata oil was most effective against Gram (+) bacteria and yeasts.

Th e goal of this study was to introduce a method for estimating stress analysis as an effi cient procedure for evaluating the strength of mitered corner joints in furniture structures. Tests were carried out to determine the eff ects of panel type, distance between the centers of dovetail holes and the edges of joints (10, 20, and 30 mm), and type of dovetail key on the load-carrying capacity of mitered corner joints under a diagonal tension load. Specimens were constructed of overlaid medium-density fi berboard (LamMDF) and particleboard (LamPb) and connected with butterfl y and H-shaped dovetail keys. Polyvinyl acetate adhesive was used to assemble the joints. Specimens were tested under diagonal tension loads and the corresponding combined stress analysis was conducted using the following formulas:Total stress at the outer edge, Total stress at the inner edge, where σb is bending stress, σa is axial stress, P is axial failure load, L is half of the span length, and t and b are the thickness and width of the joint members. Test results showed that corner joints constructed of LamMDF were 13% stronger than joints constructed of LamPb. For the specimens constructed of both panel types, a 10-mm distance between the dovetail holes and the edges of joints gave better results than distances of 20 and 30 mm. No signifi cant diff erences were observed between the 2 types of dovetail keys. Total compression stresses at the outer edge were 2 times greater than the total tension stresses at the inner edge of the joints.

“…The results of the zone of inhibition values were depicted in Percentage yield of various extracts confirm that petroleum ether extract has minimum yield (0.92% w/w) whereas aqueous extract has There were reports in the literature that methanol is a better solvent for consistent extraction of antifungal and antimicrobial agents from medicinal plants. [18,19] The antifungal activities of medicinal plants are attributed due to the presence of flavonoids and tannins. [20,21] These reports and presence of flavonoids and tannins in the methanolic extract of aerial parts of L. reticulate, confirm its potential against all selected pathogens.…”

The petroleum ether, chloroform, acetone, methanol and aqueous extracts of the aerial parts of Leptadenia reticulata Wight and Arn. (Asclepiadaceae) were studied for in vitro antifungal activity against Aspergillus flavus, Aspergillus ruantti, Candida tropicalis, Candida albicans, Trichodermata viride and Trichodermata koningii respectively. The methanolic extract exhibited prominent antifungal activity against all the selected strains. Minimum inhibitory concentration of the extracts was performed by broth dilution method and the zone of inhibition was studied by agar disc diffusion method at concentrations of 2, 5 and 10mg/ml in DMSO. Cotrimazole (25μg/ml) was used as reference control for antifungal studies. Results of MIC study revealed the antifungal activities of the extracts against the tested strains in between concentration ranges 50-400μg/ml. The present study indicates the potential usefulness of L. reticulata aerial parts as antifungal agent.
