Lecture 6 Flashcards
Adnation
Fusion of unlike parts
Chemical test for family solanaceae
- Mayer test(general for true alkaloids) gives white creamy ppt
- Vitali’s morin (specific for tropane)gives violet color
General function of family solanaceae
Inhabit parasympathetic nervous system
Solanaceae function illustrate
1.Mydriatic: before ophthalmic examination
2.Preoperative: decrease body secretions salliva
3.Bronchodilator: in athmatic cough
4.anti_spasmodic: Dec GIT motility (used in GIT and urinary tracts colic)
- Hyoscine: sedative in motion sickness
Side effects of tropane alkaloids
Double vision, dry eyes
Dry mouth
Constipation
Urine retention (unable to empty your bladder)
Repid heart rate
Percent alkaloids in belladonna
0,3 of total alkaloids calculate as hyoscyamine
Percent of hyoscyamine in Datura
0,25 of total alkaloids calculate as hyoscyamine
Percent of hyoscyamine in hyoscyamus
0,7- 1,5 % of total alkaloids calculate as hyoscyamine and hyoscine
Active constituents in tea leaves and chemical test
pseudo alkaloids (Myer test no creamy white ppt)
Tannins (10_25%) (FeCL3 test )
Volatile oil
Flavonoids
Tea origin
Prepared leaves of Thea (chamellia) sinensis family theaceae
To prepare tea
Green tea : rapid dried (streaming)
بتكسر. الانزيمات ف ال tannins مش للتأكيد ف بيفضل اخضر
Black tea : slowly dried (fermented)
الانزيمات بتاعت الاكسده بتأكيد ال tannins ل reddish brown phlobaphene
Tea uses
1.Green tea used for weight management
2. Antioxidant, anti-inflammatory, cardioprotective , hepatoprotective
3.For headache
4. CNS Stimulant and diuretic
