[5] Withaferine A [6] Yohimbine [7] Gentiogenol [8] Tuiol

[9] Erytrocentaurine [10] Gipsogenol [11] Lanatoside C [12] Escine

II. Mention 5 characters of Digoxin & Digitoxin (10M)















III. Comment the following: (10M)

[1] Strophanthus kombe used in urgently cardiac insufficiently.

From Strophanthus have very reduced
toxicity per oral than injection. They contain in position C5 un OH,
which meaning more solubility and rapid action but having short
duration than digitalis, without accumulation in organism and no attain
the toxic doses. The best active compound is G - strophanthoside or

[2] Convallaria majalis used in rest of Digitalis

The principal glycosides is convallatoxine, which on hydrolysis gives strophanthidine and (-) rhamnose.

[3] Using of licorice in traditional medicine in cases of hemorrhoids.

Presence of numerous flavonoids and isoflavonoids.

[4] The better taste of Gentiana radix.

The root of Gentian contains two bitter colored substance which give the bitter taste, there are gentisine and isogentisine.

IV. Discuss Briefly about only 3 of the following Questions:

[1] Glycyrrhiza glabra (Phytochemicals & uses). (4M)

Constituents: Alongside 25-30% starch, 3-10% glucose and others:

Sucrose, coumarine, triterpenoid, sterols, flavonoids and saponine.

The saponine are chiefly represented
by glycyrrhizin (glycyrrhizic acid) 3-5% of the weight of the dried
product. Numerous flavonoids and isoflavonoids have been isolated:
flavanones (liquiritine), chalcones (isoliquiritine) which hydrolyzed
upon drying.

Uses: anti-inflammatory properties, duodenal ulcer, gastritis, food technology, epigastria bloating, impaired digestion, cough.

[2] Oleum sesame & Oleum jecoris (4M)

Oleum Sesami

زيت الـُسـمسـم

Sesanum indicum

[ Pedaliaceae ]

liquid, oily, pal yellow, sweetish, odourless, miscible with lypophyl solvents

oleic 50% linolic 37% palmitic 7%, vitamins B, D, E, F.

Preparation of injectabil solution.

[3]. Saponaria albae radix (Phytochemicals & uses) (4M)

Constituents: contain 15 - 20 % triterpenoid saponine. Principal compound is gipsofila-saponine or gipsoside and 13 - b - hydroxy dihydrogipsogenol. Other compounds: volatile oils 018 %, lipids 0.12 % and mineral substance 6-8%.

Uses expectorant, diuretic. Gipsoside prolongate the action of narcotics, convulsivant and analeptics.
