1. A method of treating a mammal for inflammation comprising administering to said mammal a therapeutically effective amount of a pharmaceutical composition comprising a composition having the molecular formula: or a pharmaceutical formulation thereof, whereina) R1 and R2 are selected from the group
1. A method of treating a mammal for inflammation comprising administering to said mammal a therapeutically effective amount of a pharmaceutical composition comprising a composition having the molecular formula: or a pharmaceutical formulation thereof, whereina) R1 and R2 are selected from the group consisting of hydrogen, C1-C5 alkyl, and an oligosaccharide; b) R3 is selected from the group consisting of hydrogen, hydroxyl, C1-C5 alkyl, C1-C5 alkylene, C1-C5 alkyl carbonyl, a sugar, and a monoterpene group; and c) the formula further comprises R4, wherein R4 is selected from the group consisting of hydrogen, hydroxyl, C1-C5 alkyl, C1-C5 alkylene, C1-C5 alkyl carbonyl, a sugar, C1-C5 alkyl ester, and a monoterpene group, and wherein R4 may be attached to the triterpene moiety or the monoterpene moiety. 2. The method of claim 1, wherein said mammal is a human.3. The method of claim 1, wherein said administering is oral.4. The method of claim 1, wherein said administering is topical.5. The method of claim 1, wherein R3 is a sugar.6. The method of claim 5, wherein the sugar is selected from the group consisting of glucose, fucose, rhamnose, arabinose, xylose, quinovose, maltose, glucuronic acid, ribose, N-acetyl glucosamine, and galactose.7. The method of claim 6, wherein a monoterpene moiety is attached to the sugar.8. The method of claim 7, wherein R3 has the following formula wherein R5 is selected from the group consisting of hydrogen, hydroxyl, C1-C5 alkyl, C1-C5 alkylene, C1-C5 alkyl carbonyl, a sugar, C1C5 alkyl ester, and a monoterpene group.9. The method of claim 8, wherein R5 is a hydrogen or a hydroxyl.10. The method of claim 1, wherein R1 and R2 each comprise an oligosaccharide.11. The method of claim 10, wherein R1 and R2 each comprise a monosaccharide, a disaccharide, a trisaccharide or a tetrasaccharide.12. The method of claim 11, wherein R1 and R2 each comprise an oligosaccharide comprising sugars which are separately and independently selected from the group consisting of glucose, fucose, rhamnose, arabinose, xylose, quinovose, maltose, glucuronic acid, ribose, N-acetyl glucosamine, and galactose.13. The method of claim 12, wherein at least one sugar is methylated.14. The method of claim 1, wherein R4 is attached to the triterpene moiety through one of the methylene carbons attached to the triterpene moiety.15. The method of claim 1, wherein the triterpene moiety is oleanolic acid instead of acacic acid.16. The method of claim 1, wherein the pharmaceutical composition comprises a triterpene glycoside having the molecular formula: or a pharmaceutical formulation thereof, whereina) R1 is an oligosaceharide comprising N-acetyl glucosamine, fucose and xylose; and b) R2 is an oligosaccharide comprising glucose, arabinose and rhamnose. 17. The method of claim 16, wherein the triterpene glycoside has molecular formula: or a pharmaceutical formulation thereof. 18. A method of treating a mammal for inflammation comprising administering to said mammal a therapeutically effective amount of a pharmaceutical composition comprising a triterpene glycoside having the molecular formula: or a pharmaceutical formulation thereof wherein,a) R1 is an oligosaccharide comprising N-acetyl glucosamine, fucose and xylose; and b) R2 is an oligosaccharide comprising glucose, arabinose and rhamnose. 19. The method of claim 18, wherein the triterpene glycoside has the molecular formula: or a pharmaceutical formulation thereof. 20. A method of treating a mammal for inflammation comprising administering to said mammal a therapeutically effective amount of a pharmaceutical composition comprising a triterpene glycoside having the molecular formula: or a pharmaceutical formulation thereof, wherein,a) R1 is an oligosaccharide comprising N-acetyl glucosamine, glucose, fucose and xylose; and b) R2 is an oligosaccharide comprising glucose, arabinose and rhamnose. 21. A method of treating a mammal for inflammation comprising administering to said mammal a therapeutically effective amount of a pharmaceutical composition comprising a triterpene glycoside having the molecular formula:
