1 Lecture 3 Medicinal plants and MPM which contain vitamins

2 Planner Vitamins definition. Classification of vitamins.
Identification and quantity determination of vitamins content. Medicinal plants and raw material containing vitamins

3 A vitamin is an organic compound required as a nutrient in tiny amounts by an organism
Vitamins are distributed widely and are normally ingested as constituents of various food substances. Standardized, partially purified concentrates and isolated vitamins can be obtained for commercial purpose from a variety of animal, microbial, and plant sources, however, chemical synthesis is more feasible for many of the vitamins The consumption by the general public of vitamin preparations is enormous and this is one of the larger areas of the pharmaceutical industry.

4 Classification Letter classification ― the letters of the Latin alphabet were used to designate vitamins as they were discovered. A, B, C, D According to their physiological action. According to the physical properties: Soluble in fats (A, D, E, K, F) Soluble in water (vitamins of the B complex, folic acid, ascorbic acid

5 4. Chemical classification
1) Aliphatic vitamins: Vitamin C (ascorbic acid) Ascorbic acid Dihydroascorbic acid Vitamin F (lipoic acid: linoleic, linolenic, arachidonic acids ), B5 (pantothenic acid), B15 (pangamic acid) 2) Alicyclic Vitamins A (retinol) and D (D3 - cholecalciferol, D2 ergocalciferol) Cholecalciferol

6 3) Aromatic vitamins Vitamin K ( phytomenadione – K2, phylloquinone – K1)
4) Heterocyclic vitamins Vitamins E (tocopherol), B1 (thiamine), B2 (riboflavine), B6 (pyridoxine), PP (nicotinamide), nicotinic acid, B12 (cyanocobalamine), Folic acid (folacin, vitamin Bc, vitamin M, factor V), H (biotin), Ubiquinone (coenzyme Q10).

9 VITAMIN A Function: Retinol is a precursor for retinal that is used in the visual cycle and for retinoic acid that is required for maintenance of epithelial cells. In the visual cycle, opsin binds the 11-cis isomer of retinal. Light causes the conversion to the all-trans isomer which is only weakly bound to opsin. Effect of Deficiency: Night blindness and keratinization of epithelial cells. - Oral manifestations: Hyperplasia of the gingiva, gingivitis, periodontitis Sources: Vegetables, fish liver oil. Note beta-carotene is a precursor of retinol RDA: 1000 retinol equivalents (corresponds to 1000 µg retinol or 6000 µg beta-carotene). Excess vitamin A is toxic.
