Abstract

The present invention relates to selected and stabilized cell line extracts from Ajuga reptans comprising phenylpropanoids having high antioxidating capacity with a teupolioside titer of between 20% and 90% and a chromophore-free fraction of between 80% and 10%. Said extracts are for use in human and veterinary therapy and for nutritional and cosmetic purposes. Furthermore, the invention relates to a novel phenylpropanoid molecule denominated isoteupolioside.

Claims (58)

1. A pharmaceutical or cosmetic composition comprising:

a physiologically acceptable medium; and

an extract derived in part according to an in-vitro plant cell culture method from an isolated plant cell line of Ajuga reptans IRBN22 (DSM 16451) derived from undifferentiated callus tissues;

wherein the extract comprises a chromophore free fraction and phenylpropanoids comprising isoteupolioside;

the pharmaceutical or cosmetic composition comprising isoteupolioside in a sufficient amount to exhibit a pharmacological or cosmetic activity of at least one of the group selected from an anti-oxidant activity, a platelet aggregation activity, and anti-inflammatory activity, an anti-lipoxygenase activity, an anti-5-alpha-reductase activity, an anti-tyrosinase activity, an anti-fungal activity and a metal-chelating (Fe2+, Fe3+, Cu2+ e Ni2+) activity; and

the isoteupolioside is represented by a general formula (I):

wherein R1 is galactose, R2 is hydrogen, R3 is caffeic acid, R4 is a hydrogen atom and R5 is a hydrogen atom.

2. The pharmaceutical or cosmetic composition according to claim 1 , wherein the extract comprises:

from 20% to 90% by weight phenylpropanoids; and

from 80 to 10% of the chromophore-free fraction comprising oligo- and polysaccharide, protein and lipid molecules.

3. The pharmaceutical or cosmetic composition according to claim 1 , wherein the extract comprises:

between 30% and 60% by weight phenylpropanoids; and

between 70% and 40% of said chromophore-free fraction.

4. The pharmaceutical or cosmetic composition according to claim 2 , wherein the phenylpropanoids comprise between 5% and 25% by weight isoteupolioside with respect to the total mass of phenylpropanoids.

5. The pharmaceutical or cosmetic composition according to claim 2 , wherein the phenylpropanoids comprise between 30% and 65% by weight isoteupolioside with respect to the total mass of phenylpropanoids.

6. A pharmaceutical or cosmetic composition comprising:

an extract having a chromophore-free fraction and phenylpropanoids;

the extract being derived in part from an isolated plant cell line of Ajuga reptans IRBN22 (DSM 16451) and comprising 20% to 80% by weight of phenylpropanoid isomers represented by a general formula (I):

wherein:

R1 is a hydrogen atom or a monosaccharide with 5 or 6 carbon atoms or a disaccharide with 10 to 12 carbon atoms;

R2 is a hydrogen atom or is a caffeoyl (A) group or a feruloyl (B) group;

R3 is a hydrogen atom or a monosaccharide with 5 or 6 carbon atoms or a disaccharide with 10 to 12 carbon atoms or is a caffeoyl (A) group or a feruloyl (B) group;

R4 is a hydrogen atom, or a linear or branched alkyl group with 1 to 3 carbon atoms or a hydroxyl;

R5 is a hydrogen atom, or a linear or branched alkyl group with 1 to 3 carbon atoms wherein;

when R3 is a caffeoyl (A) group or a feruloyl (B) group, then R2 is always a hydrogen atom;

when R2 is a caffeoyl (A) group or a feruloyl (B) group, then R3 is always a hydrogen atom, and

R4 and R5 may be either same or different.

7. The pharmaceutical or cosmetic composition according to claim 1 , wherein the isolated plant cell line is a stabilised cell lines of Ajuga reptans.

8. A formulation comprising plant cell extract as an active ingredient in association with a pharmaceutically or cosmetically acceptable excipient, and the extract being obtained according to a process comprising the following sequence steps:

a) obtaining a biomass of plant cells derived from a selected plant cell line of Ajuga reptans IRBN22 (DSM 16451);

b) facilitating an isomerisation of teupolioside into isoteupolioside having a general formula (I):

c) recovering the extract from the biomass and forming the extract to comprise at least 20% by weight of phenylpropanoids, and a chromophore-free fraction facilitating increasing an action of the phenylpropanoids of the extract; and

9. The formulation according to claim 8 wherein the formulation is used for systemic, parenteral, oral, rectal, inhalatory, topical, transdermal, intravenous, intramuscular or subcutaneous administration.
