Physiology and ecophysiology

As discussed, Cymbopogon has a photosynthetic machinery that allows the plant to perform high rates of carbon assimilation and, at the same time, save water. In species that produce essential oil, the biogenesis of terpenoids relies on photosynthetic carbon dioxide reduction on the one hand and availability of water and nutrients, on the other. For this reason several studies have been conducted in order to assess which nutrients and at what conditions were required for an optimal production of...

Physicochemical characteristics of the essential oils from cymbopogons

Physical and chemical properties of any essential oil are of prime importance, and chemists are now working in an era when highly sophisticated instruments are available for quality and quantity analysis. Still, the specific gravity, optical rotation, solubility in dilute alcohol, and the refractive index must be determined for all oils and liquid isolates. Before the availability of modern analytical techniques, the essential oil chemists were working using their ingenuity, a highly developed...
