Summary for Patent: 5,807,555
Title: Skin treatments with Smelophyllum capense extracts
Abstract:The present invention relates to a method and composition for topically administering a Smelophyllum capense extract as a cosmetic, dermatologic, or pharmaceutical composition to promote collagen synthesis. Administration of the composition results in the firming of the skin, improves healing and is suitable for treating various pathologies accompanied with a deficiency in collagen. The extract can also be added to cell culture medium used in the culture of skin cells, particularly skin fibroblasts. The composition can contain between 0.0001% and 1% by weight of the Smelophyllum capense extract, and the extract can be obtained by extraction with a polar solvent. The composition can contain other ingredients including ascorbic acid, madecassic acid, asiatic acid, madecassoside, asiaticoside, alpha-1-protease inhibitor, collagenase inhibitors, elastase inhibitors, lysine, proline, 2-oxoglutarate and ginsenoside Ro.

Application Number:08/849,453
Patent Claims:1. A cosmetic composition comprising a cosmetically effective amount of Smelophyllum capense extract as an active ingredient, dispersed in a cosmetically acceptable excipient.

2. The composition of claim 1, wherein the concentration of the Smelophyllum capense extract is in the range of 0.0001% and 1% by weight compared to the total weight of said composition.

3. The composition of claim 1, wherein the concentration of the Smelophyllum capense extract is in the range of 0.01% and 0.25% by weight compared to the total weight of said composition.

4. The composition of claim 1, wherein said Smelophyllum capense extract is obtained from the bark of the Smelophyllum capense plant.

5. The composition of claim 4, wherein said Smelophyllum capense extract is obtained from the bark of the root of the Smelophyllum capense plant.

6. The composition of claim 1, wherein said Smelophyllum capense extract is obtained by extraction with a polar solvent.

7. The composition of claim 6, wherein said polar solvent is a lower alcohol.

8. The composition of claim 6, wherein said polar solvent is selected from the group consisting of methanol and an aqueous-ethanol mixture.

9. The composition of claim 1, which further contains an active substance selected from the group consisting of ascorbic acid, madecassic acid, asiatic acid, madecassoside, asiaticoside, alpha-1-protease inhibitor, collagenase inhibitors, elastase inhibitors, lysine, proline, 2-oxoglutarate, and ginsenoside R.sub.0.

10. A method of treating the skin of a human or animal with a cosmetic, comprising delivering to the skin a composition comprising a cosmetically effective amount of a Smelophyllum capense extract dispersed in a cosmetically acceptable excipient.

11. The method of claim 10, wherein the Smelophyllum capense extract is present at a concentration in the range of 0.0001% to 1% by weight, compared to the total weight of said composition.

12. The method of claim 10, wherein the Smelophyllum capense extract is present at a concentration in the range of 0.01% to 0.25% by weight, compared to the total weight of said composition.

13. The method of claim 10, wherein the cosmetic is selected from the group consisting of promoting the synthesis of collagen, improving skin healing, controlling the effects of skin aging, preventing the appearance of wrinkles, reducing wrinkle depth, and obtaining skin firming.

14. The method of claim 13, wherein the cosmetic treatment consists of promoting the synthesis of collagen, wherein the collagen is collagen type I.

15. A pharmaceutical composition comprising a pharmaceutically effective amount of Smelophyllum capense extract as an active ingredient, dispersed in a pharmaceutically acceptable excipient.

16. The composition of claim 15, wherein the concentration of the Smelophyllum capense extract is in the range of 0.0001% and 1% by weight compared to the total weight of said composition.

17. The composition of claim 15, wherein the concentration of the Smelophyllum capense extract is in the range of 0.01% and 0.25% by weight compared to the total weight of said composition.

18. The composition of claim 15, wherein said Smelophyllum capense extract is obtained from the bark of the Smelophyllum capense plant.

19. The composition of claim 18, wherein said Smelophyllum capense extract is obtained from the bark of the root of the Smelophyllum capense plant.

20. The composition of claim 15, wherein said Smelophyllum capense extract is obtained by extraction with a polar solvent.

21. The composition of claim 20, wherein said polar solvent is a lower alcohol.

22. The composition of claim 20, wherein said polar solvent is selected from the group consisting of methanol and an aqueous-ethanol mixture.

23. The composition of claim 15, which further contains an active substance selected from the group consisting of ascorbic acid, madecassic acid, asiatic acid, madecassoside, asiaticoside, alpha-1-protease inhibitor, collagenase inhibitors, elastase inhibitors, lysine, proline, 2-oxoglutarate, and ginsenoside R.sub.0.

24. A method of treating the skin of a human or animal with a pharmaceutical, comprising delivering to the skin of the human or animal a composition comprising a pharmaceutically effective amount, of a Smelophyllum capense extract dispersed in a pharmaceutically acceptable excipient.

25. The method of claim 24, wherein the Smelophyllum capense extract is present at a concentration in the range of 0.0001% to 1% by weight, compared to the total weight of said composition.

26. The method of claim 24, wherein the Smelophyllum capense extract is present at a concentration in the range of 0.01% to 0.25% by weight, compared to the total weight of said composition.

27. The method of claim 24, wherein the pharmaceutical treatment is selected from the group consisting of promoting the synthesis of collagen, improving skin healing, controlling the effects of skin aging, preventing the appearance of wrinkles, reducing wrinkle depth, and obtaining skin firming.
