The present invention provides a process for purifying a monoterpene or sesquiterpene having a purity greater than about 98.5% (w/w) The process comprises the steps of derivatizing the monoterpene (or sesquiterpene) to produce a monoterpene (or sesquiterpene) derivative, separating the monoterpene (or sesquiterpene) derivative, and releasing the monoterpene (or sesquiterpene) from the derivative Also encompassed by the scope of the present invention is a pharmaceutical composition comprising a monoterpene (or sesquiterpene) having a purity greater than about 98.5% (w/w) The purified monoterpene can be used to treat a disease such as cancer The present monoterpene (or sesquiterpene) may be administered alone, or may be co-administered with radiation or other therapeutic agents, such as chemotherapeutic agents.
A transdermal galantamine delivery system to an individual. The system has a high galantamine loading with suitable permeation enhancers to effect therapeutic flux rate. Acrylate polymeric reservoir with the high galantamine and permeation enhancers dissolved therein provides desirable adhesive characteristics and effective transdermal therapeutic properties for multiple-day delivery.
A transdermal nicotine salt delivery system to an individual. The system has a high nicotine salt loading to effect therapeutic flux rate. Acrylate polymeric drug reservoir with the high nicotine salt dissolved therein provides desirable adhesive characteristics and effective transdermal therapeutic properties.

A process for the preparation of compounds according to the general formula (I),
in which R is a hydrocarbon radical of an alcohol, wherein one or more alcohols of the general formula (II)
R—OH (II)
in which R is as defined above, are esterified and/or transesterified without using significant amounts of solvents, preferably without solvents, preferably under reduced pressure at temperatures below 100° C. in the presence of enzymes from the class of hydrolases with a compound according to the general formula (III),
in which R
1
is either hydrogen or a linear or branched alkyl or alkenyl group having 1 to 3 carbon atoms is provided.
The present invention provides a process for purifying a monoterpene or sesquiterpene having a purity greater than about 98.5% (w/w). The process comprises the steps of derivatizing the monoterpene (or sesquiterpene) to produce a monoterpene (or sesquiterpene) derivative, separating the monoterpene (or sesquiterpene) derivative, and releasing the monoterpene (or sesquiterpene) from the derivative. Also encompassed by the scope of the present invention is a pharmaceutical composition comprising a monoterpene (or sesquiterpene) having a purity greater than about 98.5% (w/w). The purified monoterpene can be used to treat a disease such as cancer. The present monoterpene (or sesquiterpene) may be administered alone, or may be co-administered with radiation or other therapeutic agents, such as chemotherapeutic agents.
