Cardiac & Saponin Glycoside

  1. 1. STEROIDAL OR CARDIAC GLYCOSIDE 1. Action includes both beneficial and toxic effects on heart 2. Used since 1500 BC for arrow poisoning, emetics, diuretics and heart tonics. 3. In modern treatment of CCF, atrial fibrillation & flutter 4. M/a: by affecting the availability of intracellular Ca+2 for myocardial contraction or increasing the sensitivity of myocardial contractile proteins. 5. Steroid glycosides are invariably employed in the therapeutic domain primarily for two vital reasons, namely: (a) to enhance the tone, excitability and above all the contractibility of the cardiac muscle; and (b) to increase the diuretic action, due principally to the enhanced renal circulation (an inherent secondary action). 6. Composed of 2 structures: sugar(glycone) & the non- sugar(aglycone-steroid) moieties Aglycone Moiety: 1. Steroid nucleus has –OH grp at 3- & 14- position of which the sugar attachment uses the 3-OH grp. 2. 14-OH is normally unsubstituted 3. Many genins have –OH grp at 12- & 16- positions. 4. Additional –OH grp influence the partitioning of the cardiacINTRODUCTION glycoside into the aqueous media and affect duration of action. 5. Lactone moiety at C-17 position is an important structural feature. 6. Size and degree of unsaturation varies with source of glycoside. 7. Normally plant 5 membered unsaturated lactone while animal 6 membered. Glycone Moiety: 1. 1 to 4 sugars are found to be attached to the 3b-OH grp. 2. Sugar includes: L-rhamnose, D-glucose,D-digitoxose, D- digitalose,D-digginose,D-sarmentose, L-vallarose and D- fructose. 3. Presence of –CH3CO grp on sugar affects the lippphilic character and kinetics of entire glycoside. Cardenolide Bufadienolides Unsaturated butyrolactone Pyrone ring ring Lactone has single double 2 double bond attached at bond & attached at C-17 of 17^a position steroidal nucleus

Best grown when allowed to seed itselfCultivation 6. Seeds should be mixed with fine sand in order to ensure even distribution. 7. Before sowing soil is sterilized. 8. Sown in spring, the plant is not blossom till the following year. 9. In dry season, sufficient water is supplied. 10. In 1st yr, long stalk with rosette of leaves is produced. 11.

  11. 11. 1. Referred to as “Natural detergent” because of their foamy texture 2. Name derive from soapwort plant (saponaria), the root of which was used historically as a Soap(Latin sapo-soap) 3. Tendency to froth formation when shaken with water 4. Hemolytic, sneezing effect, toxicity, complex formation with cholesterol & antibiotic properties. 5. Consists of polycyclic aglycone that is either a choline steroid or triterpenoid attached via C3 and ether bond to sugar side chain. 6. The aglycone is referred to as the sapogenin and steroid saponins are called sarsaponins. 7. The ability of saponin to foam is caused by the combination of the non polar sapogenin and the water soluble side chain. 8. Bitter and reduce the palatability of livestock feeds. 9. If triterpenoid aglycone, taste as glucuronic acid replaces sugar in triterpenoid. 10. For example, saponins found in oats and spinach increase and accelerate the body’s ability to absorb Calcium and Silicon, thus assisting digestion. 11.

Insoluble in organic solvents like petroleum ether, chloroform and acetone etc. 5. Bitter in taste 6. Non-alkaline in nature 7. Produce sneezing and have property of lowering surface tension 8. Hydrolysed by acids, alkalies to yield aglycone called sapogenin Physiological Properties: 1. Extremely toxic to fishes but not poisonous to man when taken orally 2. Very dilute solution of saponins hemolyses RBC (hemolysis takes place due to the formation of complex with the cholesterol or erythrocyte membrane causing its destruction (chief property of saponin, very rarely shown by any other plant product. 3. Accelerate the germination and growth of the seeds. 4. Shows fungicidal, antifertility, molluscidal, blood purifying, abortifacient, anthelmintic, sedative & antispasmodic effects. Occurrence: 1.
