blisters.
 Internally, act as Emmenagogue, to produce abortion (larg
dose).
 Origin: dried sclerotium or resting stage of the fungus, Claviceps
purpurea, Family Claviciptiaceae developed on the ovary of the rye plant,
Secale cereale, Family Graminae.
 yields not less 0.2% of the total alkaloids of Ergot, calculated as
ergotamine.
The slerotium
shape: subcylindrical, 3-4 sided, tapering towards both ends.
color: brownish to nearly black.

taste: an oily disagreable.?????
T.S. sclerotium
 an outer region of a few layers of very compact, dark purple
to dark brown more or less obliterated cells ‫مطموس‬, in regular
longitudinal rows.
 The colour of that layer turns red with 66% H2SO4, or chloral
hydrate (T.S.) and violet with alkali.
 The remainder of the structure consists of a closely compact
pseudoparenchyma, consisting of colourless, very short,
rounded oval or irregular cells, varying in size.
 They have thin, colourless, highly refractive chitinous walls,
rich in fixed oil and protein.
Active Constituents:
 Twelve alkaloids of lysergic acid type, divided into 6 isomeric
pairs. Of which water soluble are ergometrine (ergonovine),
ergometrinine.
 The remaining five pairs are insoluble in water; ergotamine ,
ergosine, ergocristine, ergokryptine and ergocornine.
N.B.: Ergotoxine is a mixture of
ergokryptine, ergocornine and ergocristine
and their corresponding isomers.
Detection of Ergot in Flour:
This test as well as the microscopical features of the powder are
the bases of detection of Ergot in flour.
1- for ergotoxine alkaloids :
Van-Urk’s test: Ergot alkaloids + Van-Urk’s reagent (p-
dimethylaminobenzaldehyde in H2SO4 + traces FeCl3) →
Deep blue color.
2- Test for colouring matter(pigment sclererythrin):
ether extract + 10 drops of dilute sulphuric acid → Filtrate + 1cc. of
a cold saturated solution of sodium bicarbonate → red to violet
colour (in the aqueous layer).
Ergometrine is used as an Oxytocic (faster stimulation of
uterine muscle), and is injected during the final stages of
labor to assist delivery and
Ergometrine is used to reduce post-partum hemorrhage.
Bleeding is reduced because of its vasoconstrictor effects,
and it is valuable after caesarian operations.
Ergotamine is used in the treatment of acute attacks of
migraine, and may be combined with caffeine.
Lysergic acid is used in preparation of L.S.D (Lysergic
acid diethylamide) (recreational ‫او‬ ‫السعاده‬ ‫استحداث‬
‫ترفيهي‬ drug)
 It consists of the unicellular fungus Saccharomyces siccum,
Family Saccharomycetaceae.
constituents:
 About 13% proteins, 0.27% oil.
 Enzymes as zymase, invertase, maltase.
 Glycogen, fat, ergosterol and zymosterol.
 It’s an important and cheap source of vitamin B.
Uses:
 The chief use of yeast is as a source of vitamin B.
 Dried yeast is used in many dietetic preparations.
 Dried yeast of dead cells is used in making tablets in
Pharmaceutical industry.
 It’s the mould fungi of Penicillium notatum and P. chrysogenum
, Family Aspergillaceae.
Active constituents:
 An antibiotic principle named penicillin, it’s unstable acid,
sodium and calcium salts of penicillin are prepared and used for
i.m. administration.
Uses:
 1- Penicillins are active against many pathogenic gram-
positive bacteria.
 2- Also used in controlling infections caused by some gram-
negative bacteria.
 They are secondary metabolites produced by certain fungi.
 Aflatoxins are the most important mycotoxins, because they
are:
 Carcinogenic.
 Mutagens, causing chromosomal aberrations.
 Teratogens causing malformation in embryos.
 They cause hemorrhage, necrosis of the liver as well as
kidney lesions.
 They are difurocoumarin cyclopentone derivatives as
aflatoxin B1, B2, G1 and G2 from the fungus Asperigillus
flavaus and A. parasiticus.
