The essential oils associated with the flowers of Tithonia diversifolia (Hemsl.) A. Gray were extracted and characterized via hydrodistillation and Gas Chromatography. Hydrodistillation was done in an all-glass Clevenger-type apparatus. The extracts from the hydrodistillation were subjected to gas chromatography where the components of the essential oils were separated based on their molecular ...

Rosemary (Rosmarinus officinalis L.) is a plant with needle-shaped leaves.

3-Hydroxypyridinium and 3-(hydroxymethyl)pyridinium O-terpenyl aryldithiophosphonates were obtained by the reactions of 3-hydroxypyridine 3-(hydroxymethyl)pyridine with aryldithiophosphonic acids on basis (1R,2S,5R)-(−)-menthol, (1S)-endo-(–)-borneol, racemic isoborneol, carvacrol. The salts possess high antimicrobial activity against Bacillus cereus Candida albicans.
