Gas chromatography-mass spectrometry and multivariate curve resolution were applied to the differential analysis of the volatile components in Agrimonia eupatoria specimens from different plant parts. After extracted with water distillation method, the volatile components in Agrimonia eupatoria from leaves and roots were detected by GC-MS. Then the qualitative and quantitative analysis of the v...

Non-volatile storage connected as memory (NVRAM) offers promising opportunities for simplifying and accelerating manipulation of persistent data. Load and store latency is potentially comparable to that of ordinary memory. The challenge is to ensure that the persisted data remains consistent if a failure occurs during execution, especially in a multithreaded programming environment. In this pap...

The antioxidant, antifungal and antibacterial potentials of volatile oils and oleoresin of Cinnamomum zeylanicum Blume (leaf and bark) were investigated in the present study. The oleoresins have shown excellent activity for the inhibition of primary and secondary oxidation products in mustard oil added at the concentration of 0.02% which were evaluated using peroxide, thiobarbituric acid, p-ani...

The pulp of pitanga (Eugenia uniflora L.) is used to prepare pitanga juice. However, there are no reports on the identification and quantification of the main constituents in pitanga pulp. The aim of this study was to identify and quantify the major volatile and non-volatile low-molecular-weight constituents of the pulp. Isolation of volatile compounds was performed by solvent-assisted flavor e...

it has been observed that most of the chemical entities have high lipophilicity and poor aqueous solubility, which result in poor bioavailability. in order to improve the bioavailability, the release behavior of such drugs should be improved. although there are numerous techniques to handle solubility related issue, but they are expensive due to involvement of complicated equipments, advanced m...

Hydro-distilled volatile oils from the flowers and leaves of Eupatorium cannabinum L. which gathered in Touchal on Mountain Alborz (Tehran province) in Iran were investigated mainly by a combination of GC and GC/MS. Thirty-nine components were identified in the oils. The main constituents of the essential oils in flowers and leaves were germacrene D (27.3%, 37.1%), gemacrene B (12.4%, 11.7%) an...

Analysis of common volatile constituents between herbal pair (HP) Ephedra sinica Stapf (ESS)-Zingiber officinal Rosc (ZOR)and its single herb was performed by the method of GC-MS and alternative moving window factor analysis (AMWFA). Identification of the compounds was also assisted by comparison of temperature-programmed retention indices (PTRIs) on the OV-1 column with authentic samples. AMWF...
