We now have separation of the Three Essentials, the oil or Sulfur, the Mercury as alcohol, and the Salt, which still lies hidden in the extracted Rosemary residue. The next step of the process is the purification of our separated essentials. The Mercury and Sulfur are redistilled a number of times until they are highly refined in the physical sense, but also exalted in the spiritual sense. 

Vegetable oil (none) or antioxidants in vegetable oil were added as ingredients in the raw meat emulsions for bologna manufacture. The antioxidants tested were 500 ppm sodium erythorbate (eiythorbate), 200 ppm sodium nitrite (nitrite), and 0.075% rosemary extract (rosemary). The emulsions were cased, cooked, and irradiated at 3 kGy. Volatile compounds measured die next day, and expressol as square root of peak ar count. The numbers were means of four replicates. Adopted from ref (26).

In addition to primary-contaminated or microbiologically susceptible natural raw materials, many multiactive agents classes are based on an alcoholic or phenolic structure. These extracts, such as melissa extract, rosemary acids, phenylethylalcohol II, 1.6.] etc., often show strong microbial efficacy and can be used to support product preservation in cosmetics (Eggensperger, 2001). 

Several other naturally occurring antioxidants have been identified in oils. Sesamol [533-31-3] (6) occurs as sesamoline [526-07-8], a glycoside, in sesame seed oil. FemUc acid [1135-24-6] (7) is found esterified to cycloartenol [469-38-5] in rice bran oil and to 3-sitosterol in com oil. Although it does not occur in oils, rosemary extract has also been found to contain powerful phenoHc antioxidants (12). 

The most popular natural antioxidants on the market are rosemary extracts and tocopherols. Natural antioxidants have several drawbacks which limit use. Tocopherols are not as effective ia vegetable fats and oils as they are ia animal fats. Herb extracts often impart undesirable colors or flavors ia the products where used. In addition, natural antioxidants cost considerably more than synthetic ones. Despite this, the pubHc s uncertainty of the safety of synthetic antioxidants continues to fuel the demand for natural ones (21).

Synthetic analogues or derivatives of a-tocopherol which have better antioxidant properties can be introduced. Many natural antioxidants such as flavonols, flavones, tea leaf catechins, rosemary antioxidants and spice extracts have been reported to be more active than BHA, BHT or the tocopherols in model systems. The food applications of these compounds need to be explored further. 

Negative atmospheric pressure chemical ionization (APC) low-energy collision activation mss spectrometry has also been employed for the characterization of flavonoids in extracts of fresh herbs. Besides the separation, quantitative determination and identification of flavonoids, the objective of the study was the comparison of the efficacy of the various detection systems in the analysis of flavonoids in herb extracts. Freeze-dried herbs (0.5g of chives, cress, dill, lovage, mint, oregano, parsley, rosemary, tarragon and thyme) were ground and extracted with 20 ml of 62.5 per cent aqueous methanol. After sedimentation the suspension was filtered and used for HPLC analyses. Separations were carried out in an... 

In the search for environmentally benign chemicals that might deter birds such as starlings, crows, or pigeons from roosting en masse, spices and herbs such as rosemary, cumin, and thyme look promising. In some experiments, the birds feet were immersed in oil extracts of the spices. Starlings also avoided perches treated with starch mixes of (R)-limonene, (S)-limonene, (3-pinene, or methiocarb. The first three occur in rosemaiy, cumin, and thyme (Clark, 1997). 

Dynamic extractions of the organic flavonr and fragrance componnds from dried lavender flowers and rosemary leaves nsing SCCO2 were carried ont. The data from the lavender and rosemary extractions were fitted to a model to prodnce the characteristic extraction cnrve. Using data obtained from rosemary extractions, an extrapolation method derived from the model was used with data from shorter extractions to show that the model provided qnantitative analytical information (Walker et al., 1994). 

Based on the same principle of modulation of drug absorption, other less known botanicals could produce similar or different effects compared to St. John s wort. Rosemary (Rosemarinus officinalis Labiatae) is a commonly used dietary botanical that has been found to have a chemopreventive effect (24). Furthermore, in drug-resistant MCF-7 human breast cancer cells expressing P-glycoprotein, methanol extracts of Rosemary at two concentrations (16.5 and 85 pg/mL) inhibited the efflux and increased intracellular accumulation of doxorubicin and vinblastine, two chemotherapeutic drugs that are known substrates of P-glycoprotein. Treatment of drug-resistant cells with the extracts also increased the cytotoxic effects of doxorubicin. On the other hand, in wild-type MCF-7 cells that do not express...
