Extracts of many types of plants that are utilized as flavoring and seasoning agents in foods, have been used therapeutically for centuries. Sulphur compounds, terpenes and terpene derivatives, phenols, esters, aldehydes, alcohols and glycosides have shown antimicrobial and antioxidant functions. So far many literatures about the potential use of bioactive phytochemicals in food and pharmacy in...

in multi-step organic syntheses, the protection and deprotection of tetrahydropyranyl (thp) ethers is one of the most frequently used methods. over the years, different methods have been used from various catalytic systems for the protection of hydroxyl groups as thp ethers and their deprotection. herein we have reported that various alcohols and phenols have been efficiently converted to the c...

We disclose herein a highly enantioselective protocol for the Brønsted acid-catalyzed addition of indoles and phenols to in situ-generated ortho-quinone methides which deliver broadly substituted diarylindolylmethanes and triarylmethanes, respectively, in a one-pot reaction under very mild conditions. A chiral phosphoric acid catalyst has been developed for this process serving to convert the s...

Extracts of Mandragora autumnalis (mandrake) fruit have been analyzed by GC–MS. One-hundred and thirty-five compounds were identified in extracts obtained from the fruit after removal of the seeds – twentythree n-alkanes, one branched-chain alkane, two cyclohexanes, eight alkenes, two branched-chain alkenes, three alcohols, three aldehydes, six ketones, eight heterocyclic compounds, four thio c...

Although the literature contains a number of reports regarding the bactericidal efficiency of certain specified concentrations of sodium hydroxide against various test organisms, very little of this information is presented in a manner suitable for mathematical analysis. To obtain the data required for analysis, an experimental study was made of the bactericidal efficiency of sodium hydroxide. ...
