Problems solved by technology

The disadvantage of the use of these inhibitors, however, is that antisense oligonucleotides and ribozyme molecules are not readily available and many vitamin D antagonists, such as e.g. cortisone, have severe side effects.
These compounds and their formulations, however, are not always in rosacea and acne treatment.
Some side effects related with use of metronidazole, including dry skin, skin redness or irritation, may occur.

Extraction Process

[0063]Crushed dry leaves of Tambourissa trichophylla are extracted with a mixture of ethanol and water (in a volume ratio of 70:30). The mixture is stirred and heated at a temperature below 60° C. for a period of about 30 minutes to about 1 hour to perform the extraction. The solid plant material is removed, and ethanol is then removed leading to a precipitate, which is filtered out of the remaining aqueous solution. The aqueous solution is then treated by liquid-liquid extraction with ethyl acetate. The acetate fraction is retained for acetate distillation and the consequent aqueous solution is freeze-dried.

[0064]The final extract is characterized by thin layer chromatography (TLC), using HPLC standard methods and spectrophotometry. The final composition shows a content of 19% to 21% by weight of polyphenols and less than 2% by weight rutin and nicotiflorine. The presence of epicatechin is also detected by TLC.

Cosmetic Formulation Examples

[0065]Emulsions containing various concentrations of Tambourissa trichophylla leaf extract were prepared in accordance with Example 1. The emulsion concentrations are set forth in Table 1. Phases A and B of the emulsions were weighed separately. The separate phases (A & B) were heated to 80° C. and mixed under high stirring A to B. The mixture was cooled down to 35° C. while stirring and component C was added. The compounds listed members of component D were mixed until a transparent solution was obtained and component D was then added to the formulation. The final formulation was cooled down to room temperature while stirring continued.

[0066]The final compositions were cosmetic oil in water emulsions: excipient (A) was white and formulations containing extract according to Example 1 (B & C) were beige to beige-orange.

Anti-Inflammatory Activity on Prostaglandin-2 (PGE-2)

[0067]A test was performed on HUVEC (human umbilical vein endothelial cells). HUVEC were incubated for 24 hours without (control) or with various concentrations of the extract from to example 1, and in presence of an inducer: VEGF (venous endothelial growth factor). PGE-2 levels were measured in the medium by the ELISA method. Significance was evaluated by the Student test.

Abstract

Medicaments or cosmetic compositions for the treatment or alleviation of skin or mucous membrane diseases or disorders related to an enhanced level of anti-microbial peptides or proteins comprising Tambourissa plant extracts, which may comprise polyphenols.

Description

FIELD OF THE INVENTION[0001]This invention relates to medicaments and cosmetic compositions comprising Tambourissa plant extracts that in turn comprise polyphenols for the treatment or alleviation of skin or mucous membrane diseases or disorders related to an enhanced level of anti-microbial peptides or proteins. This invention also relates to processes for preparing a Tambourissa plant extract, the extract itself, and uses of the extract.BACKGROUND OF THE INVENTION[0002]The Tambourissa genus belongs to the Monimiaceae family and comprises about 43 species found throughout the western islands of the Indian Ocean, such as Madagascar, Comoros and the Mascarenes islands (Mauritius and Reunion). The various Tambourissa species tend to show endemic specificity as most of them are localized in only one island and in only one habitat.[0003]Tambourissa trichophylla (Baker) growths in Madagascar and Comoros. It is a tree of from about 5 meters to about 12 meters high. The leaves are opposite...
