DESC:Field of Invention:
The present invention relates to a bioavailable composition of natural compounds. More specifically, the invention relates to a composition which uses a synergistic combination of an essential oil and an emulsifier for enhancing bioavailability and slow release profile of the natural compounds.

Background of Invention:
The bioavailability of the drugs or pharmaceutical compounds is majorly based on solubility of said compounds in water, since water solubility of the natural compounds plays a major role in determining the amount of compounds which may be absorbed after oral administration.

Despite the tentative popularity of natural compounds, as alternative treatment means, demonstrable efficacy has remained elusive for many of these compounds because of their hydrophobic nature. Due to their hydrophobic nature, said natural compounds demonstrate a low solubility. The low solubility, in turn, results in poor systemic absorption of these natural compounds and hence low bioavailability.

A number of techniques have been employed to enhance the bioavailability of the hydrophobic compounds. One such technique is addition of certain components which are classified as ‘bioavailability enhancers’ or ‘bioenhancers’. Bioavailability enhancers are drug facilitators, which by themselves do not show any drug activity but when used in combination with drugs or active ingredients they enhance the activity of the drug molecule by increasing penetration of the drug across the cell membrane, potentiating the drug molecule by conformational interaction, improving the solubility of the drug molecule, and making target cells more receptive to drugs.

Chen, Jun, et al in their article titled “Potential of Essential Oils as Penetration Enhancers for Transdermal Administration of Ibuprofen to Treat Dysmenorrhoea” published in Molecules,2015, have clearly established the potential use of the plant essential oils as effective permeation enhancers, However, the article focused, in particular, on the use of Essential Oils as permeation enhancers for ibuprofen. The Article observes that essential oils and their constituents can easily penetrate through the skin into the blood stream.

Essential oils are generally isolated from plant material by distillation methods, usually steam or hydro-distillation. Essential oils are variable mixtures of principally terpenoids, specifically monoterpenes [C10], sesquiterpenes [C15], diterpenes [C20] and a variety of other low molecular weight aliphatic hydrocarbons (linear, ramified, saturated and unsaturated), acids, alcohols, aldehydes, acyclic esters or lactones and exceptionally nitrogen- and sulphur-containing compounds, coumarins and homologues of phenylpropanoids.

The effectiveness of terpenes as skin penetration enhancers has been established by Williams, A. C. and Barry, B. W. in their article titled “Terpenes and the Lipid–Protein–Partitioning Theory of Skin Penetration Enhancement” published in Pharmaceutical Research, January 1991, Volume 8, Issue 1, pp 17–24.

The same has been further highlighted by Sapra, B. et al in their article titled “Percutaneous permeation enhancement by terpenes: mechanistic view” published in AAPS J., 10 (1) (2008), pp. 120–132. According to Sapra et al, Terpenes are included in the list of Generally Recognized as Safe (GRAS) substances and have low irritancy potential. Their mechanism of percutaneous permeation enhancement involves increasing the solubility of drugs in skin lipids, disruption of lipid/protein re-organization and/or extraction of skin micro constituents that are responsible for maintenance of barrier status. Hence, they appear to offer great promise for use in transdermal compositions.

US5716928, assigned to Avmax, Inc., further establishes the use of Essential oils for enhancing the bioavailability of various pharmaceutical actives.

Therefore, the use of Essential Oils as permeation enhancers has been concretely established in past few years. This has made them an attractive and safe option for various synthetic permeation enhancers.

950/CHE/2010, of Arjuna Natural Extracts Ltd., tried using curcumin essential oil, comprising Ar-turmerone, for increasing the bioavailability of curcumin.

Additionally, emulsifiers have also proved to be effective for enhancing the bioavailability. Especially in case of Self-Nanoemulsifying Drug Delivery System, wherein a right blend of emulsifier(s) is necessary to achieve a better bioavailability, as can be seen from article titled “Preparation and In Vitro Evaluation of Self-Nanoemulsifying Drug Delivery System (SNEDDS) Containing Clopidogrel” by Pathak, Chirag Vilas et al in “Int. J. Pharm. Sci. Rev. Res., 25(1), Mar – Apr 2014; Article No. 02, Pages: 10-15”.

Therefore, the present inventor describe compositions which contains natural compound(s) combined with an essential oil and an emulsifier with a view of enhancing the bioavailability of the natural compound(s) and provide an economical method for manufacturing the composition of invention. Essential oil and emulsifier synergistically enhance the bioavailability of the natural compound(s).

Summary of Invention:
The invention provides a novel pharmaceutical, nutraceutical, dietary supplement, food/feed supplement or additive and/or herbal composition which comprises of a natural compound(s), an essential oil(s) and an emulsifier(s).

In main aspect, the composition of the invention demonstrates enhanced bioavailability and also achieves slow/sustained release of the natural compound(s).

The enhanced bioavailability is due to the synergistic activity of the essential oil and the emulsifier, wherein essential oil has a dual purpose of aiding in enhancing the bioavailability, acting as co-solvent in the composition and directly enhancing the bioavailability as a permeation enhancer, thereby synergistically working with emulsifier to enhance the bioavailability of natural compound(s).

The viscosity of the synergistic composition leads to sustained release of the active ingredient.

In another aspect, the invention provides a process for preparation of the composition of the invention.
