Facts about Aloe –
John Heinerman states that no other herb has been touched so highly by medical and dental practioners in modern times. Aloe contains 96% water , making it possible to supply that vital ingrident to injured tissue without closing off the needed air supply.
Aloe’s reputation as miracle cure-all is reinforced by one Lub-bock , Texas , woman’s story. Possessing a wart on her arm as large as a pencil eraser , she began covering it with a piece of cotton soaked in aloe gel . Additional gel was applied every 3 hours. The wart had disappeared after two weeks without slightest trace of a scar.
ABOUT ALOE VERA –
Aloe vera is a perennial stemless or short – stemmed succulent plant with non fibrous leaves about 30-40 cm long and 5 cm in diameter,growing 50-100 cm long and spreading by offsets in tropical regions all over the world. It is common practice in Central America and Mexico to use the gel and eated leaves for burns and other inflammatory skin conditions.
The leaves are thick , fleshy , and green to grey-green in color. The margins are serrated and possess small white teeth like projections.
There are two parts of leaf – (1)LeafJuice
(2) Gel
Gel is odourless , clear liquid present in innermost part of leaf. Aloe juice oozes out from leaf when cut and is yellow coloured and has bitter taste .
*The name “aloe vera” is usually applied to the gel obtained from centre of fleshy leaves of various species of aloe.
ISOLATION OF MUCILAGE –
The mucilaginous layer is removed mechanically from leaves and purified by precipitation from water – ethanol. The material obtained has high ash content of nearly 12.9% which is removed by dialysis.
The mucilage isolated is white, amorphous product that is corresponding to hexosan. On hydrolysis, it yields glucose and mannose.
LAB STUDY–
The activity against fungi of A.vera gel was examined on 4 fruit pathogens :
Penicillium digitalium , P. expansum , Botrytis cinerea and Alternaria alternata.
The natural gel supresses both germanium and mycelial growth of the fungi , P. digitalium and A. alternata are sensitive species. Spore survival of P. didgitalium , A. alternata and B. cinerea was decreased by 15-20 % at 1 micrometer , but it affects P. expansum only when the concentration exceeded 10,000 microlitre.
The effectiveness of gel rose with increase in concentration involving 95% reduction in spore survival of P. digitatum and A. alternata at 105 micrlitre.
The inhibitory effect of plant on fungal colony growth was seen at 1 microlitre, when 67-69% declination in radial growth was recoreded for P. digitatum , A. alternata and B. cinerea. aqueous extract of aloe vera was very effective against Pseudomonas solancearum .
