Cinnamomum burmanni has antifungal and antibacterial properties, including alkaloids, tannins, flavonoids, saponins, terpenoids, essential oil content of cinnamaldehyde, eugenol, safrole. This study aims to determine the properties against Streptococcus mutans Staphylococcus aureus, Candida albicans tropicalis, antioxidant, flavonoid microwave-assisted extraction (MAE) extracts from C. bark. be...

A precipitation hardened maraging TRIP steel was analyzed using a pulsed laser atom probe. The laser pulse energy was varied from 0.3 to 1.9 nJ to study its effect on the measured chemical compositions and spatial resolution. Compositional analyses using proximity histograms did not show any significant variations in the average matrix and precipitate compositions. The only remarkable change in...

Moonbeams and Elements Written by G. Jeffrey Taylor Hawai'i Institute of Geophysics and Planetology To determine how a planetary body formed and evolved, we must determine the chemical compositions of distinctive geologic regions on it. It is never possible to obtain enough samples of a planet to do this job thoroughly, so planetary scientists have searched for ways of determining chemical comp...

Chromium doped ZnS nanocrystals with pure and 10% compositions were synthesized by chemical co-precipitation route. Samples were characterized by X-ray diffraction (XRD) technique, Fourier transforms infrared spectroscopy (FTIR) and UV-Visible spectrometer. Lattice parameter ‘a’ decreases and grain size increases with increasing Cr concentration. XRD study shows that both the samples have cubic...

Radix Bupleuri (RB), also named Chaihu in Chinese, is a commonly used herbal drug in traditional Chinese medicine (TCM), and the processing of RB with vinegar to prepare vinegar-baked Radix Bupleuri (VBRB) has a long history in the clinic of TCM. In the present study, GC-MS coupled with multivariate data analysis was applied to compare the volatile components between crude and two vinegar proce...

According to distribution of genus Achillea, two main centers of diversity occur in S.E. Europe and S.W. Asia. Diversified essential oil compositions from Balkan Peninsula have been numerously reported. However, report on essential oils of Achillea species growing in Turkey, which is one of the main centers of diversity, is very limited. This paper represents the chemical compositions of the es...
