Turmeric, oil

Separation and purification of three turmerones, e.g. ar-turmerone, a- and P-turmerone, from turmeric oil extracted by supercritical carbon dioxide gave 71% purify by weight. Subsequently, purification using a normal-phase silica gel 60 column could separate and purify three major turmerones with 86% purify by weight of ar-turmerone and 81% purity by weight of a- and P-turmerone. These were identified by liquid-solid chromatography, NMR qualification and HPLC quantification, respectively (Li-Hsun Chang et al., 2006).

Fufang Danshen Diwan) and six extracts (Notoginseng root extract, triol saponins Notoginseng root and stem extract, total saponins Salvia root and stem extract, total phenolic acids Zedoary turmeric oil and Centella extract) and the so-called LC-specific chromatograms of two solid oral dosage forms and six extracts have been standardized [33]. 

The composition of turmeric oil (curcuma) has been reviewed [225]. L.CO2 has been used to selectively extract turmeric root as reported by Naik [16]. These researchers obtained a 3.4% yield in 2 hours at 60 bar and 20°C and compared it to a steam distillation yield of 5.5% in an unspecified time. Under these mild conditions of CO2 extraction, this reviewer thinks it unlikely that all the extractives would be removed and suggests further research at higher pressure for a longer time. 

Essential oils are complex mixtures of volatile substances contained in natural plant materials. They are obtained from different parts of plants, their flowers (such as jasmine oil), flowering stalks or straw (such as mint and thyme oils), fruits or seeds (such as cumin, pepper and juniper oils), fruit pericarp (such as citrus oils), wood (sandal oil) leaves (bay oil), bulbs (such as garlic oil), rhizomes (such as sweet flag and turmeric oils) and roots (such as gentian oil). Essential oils are obtained by three basic procedures or their combinations ... 

Turmeric oil is distilled from the roots of Curcuma longa, one of the-Zingiberaceee indigenous to India, and cultivated also in China and Southern Asia, etc. The oil, which is not of commercial importance, is obtained to the extent of about 5 per cent, as a thick yellow oil having the following characters —...

The botanical insect repellents, cinnamon oil, lemon eucalyptus oil, sandalwood oil, and turmeric oil, were evaluated in the laboratory against fourth instars of Aedes aegypti, Aedes albop-ictus, and Culex pipiens complex. The sandalwood oil was the most effective larvicide, killing the larvae of all three species of mosquitoes in a relatively short time. Twenty-one commercial insect repellents shown in Table 21.3 including 12 natural, 6 deet-based, and 3 synthetic repellent products were evaluated as larvicides against the larvae of Aedes albopictus in the laboratory. Ten of the 12 botanical products at 0.1% concentration provided 57%-100% mortality at 24 hours posttreatment. " ...
