The log P value of the nonionized alkaloid is 0.93 (Chamberlain et al., 1996); according to Seckar et al. (2008), the log P values for nicotine hemisulfate at pH = 3, 7 and 9 are −1.60, 0.16 and 1.25, respectively. Pure natural nicotine is levorotatory: [α]D20=-...
2022, Journal of Applied Research on Medicinal and Aromatic Plants Citation Excerpt : Further, the recovered compounds often result in solvent poisoning caused by large solvent volume requirements during extraction. Considering these, non-conventional and innovative techniques such as enzymatic assisted extr...
Therefore, the anhydrous proton conductor consisting of a non-expensive material is necessary for advanced PEMFC technology. The proton transport under anhydrous or low humidity conditions is a non-vehicular mechanism, in which only the protons are mobile from site to site without diffusible water ...

Aromatic aldehydesMalononitrileDimedoneUltrasonicationGreen chemistryTetrahydrobenzo[b]pyransAn environmentally benign novel strategy is developed for the synthesis of tetrahydrobenzo[b]pyrans by using thiamine mononitrate as a green catalyst, with the help of a conventional as well as non-conventional energy...
Aromatic turmerone, 伪-turmerone and zingiberene were also obtained. Qualitative and quantitative analyses alcoholic extract of Andrographis paniculata using TLC, revealed that the extracts contain three important compounds in total lactone of 30.49% w/w. There are andrographolide,14-deoxy-11-12-di...
were analyzed under the same condition. The sample was equilibrated for 20 min at 60 °C in the HS of the vial. After the equilibration, a 50/30 μm DVB/CAR/PDMS SPME fiber (57348-U, Supelco) was exposed to the HS for 30 min at 60 °C. PDMS is used for non-polar an...
Literature data concerning the relationship between bacterial cell hydrophobicity and exposure to aromatic compounds are ambiguous and related to the properties of both substances and species of bacteria. For example, Kaczorek et al. (2010) reported an increase in CSH of Aeromonas hydrophila under ...
Regulation of ferroptosis by bioactive phytochemicals: Implications for medical nutritional therapy 2021, Pharmacological Research Citation Excerpt : Whether other chemical types of plant-derived compounds, such as quinones, aromatic and aliphatic compounds, have effects on ferroptosis remain to be determined...
The invention also provides for various pharmaceutical compositions of the same and methods for treating diseases responsive to modulation of P2Y1 receptor activity. BACKGROUND OF THE INVENTION Purinoreceptors bind to and are activated by a variety of both ribosylated (nucleotide) and non-ribosylated...
