Cultivation of cocoa :
Cocoa is cultivated up to an elevation of 1000m above sea level.
Soil well drained good quality soil with the capacity to hold moisture.
Rainfall cocoa plant can tourate a rainfall 150 cm per annum.
Cocoa plan is sun loving, but cannot bear direct sunlight.
Preparation of cocoa butter:
Cocoa seeds contains about 50% of cocoa butter.
Seeds are separated from pods and allowed to ferment their colour from white to dark reddish brown due to enzymatic reaction.
Fermentation process take place at 30-40C.
After that the seeds rotated at 100-140C.
Seeds are then cooled immediately.
The kernees are then fed to hot rollers which yield a pasty mass during cocoa butter.
  These seeds contain about 59% of fat.
 DESCRIPTION:-
NATURE -                  solid, brittle below 25C
COLOUR –                yellowish white
ODOUR-                   pleasant
SOLUBILTY –          insoluble in water

STANARDAS: -
Specific gravity                 0.858- 0.864
Melting point                   30-35C
Iodine value                 30-35
ACTIVE CONSTITUENTS:
It contains of glycerides of stearic acid (34%).
Oleic acid (37%)palmitic acid (25%). And small quantity of arachdic acid and linoleic acids.
The non-greasiness of products is due to its glyceride structure.

CHEMICAL TEST
1 g of Theobroma oil dissolved in

Pharmacognosy of Agar

Image
                                      AGAR AGAR Agar is derived from the polysaccharide agarose , which forms the supporting structure in the cell walls of certain species of algae, and which is released on boiling. These algae are known as agarophytes and belong to the Rhodophyta (red algae) phylum. Agar is actually the resulting mixture of two components: the linear polysaccharide agarose, and a heterogeneous mixture of smaller molecules called agaropectin .                                              FIG;-chemical structure of agarose Synonyms : Agar-agar, Vegetable Gelatin, Japanese or Chinese Gelatin, Japanese Isinglass. Biological Source : It is the dried colloidal concentrate prepared from the decoction of various species of the genus Gelidium , family Gelidaceae. The genus Gelidium provides about 35% of the total raw material. Japanese agar is obtained from Gelidium amansii . It is also obtained from genus Gracilaria , family Gracilariaceae. Other

Pharmacognosy of Shark Liver Oil

                    SHARK LIVER OIL Synonym : Oleum Selachoide. Biological source: Shark liver oil is extracted from the livers of deep-water sharks which typically inhabit the cold, non-polluted waters of the sea. Shark liver oil is typically obtained from sharks that are caught as a by-product of deep-sea fishing, making a valuable remedy from a natural resource that would have otherwise gone to waste. Shark liver oil is the fixed oil obtained from the fresh and carefully preserved livers of various species of shark, mainly Hypoprion brevirostris (lemon shark), family- Pleuonectidae, order-Selachii and Galeorhinus zyopterus. In India, Scoliodon, Carcharias, and Sphyrna are abundant among the species, and are generally utilize for the extraction purpose. Geographical Source: The oil is produced mainly on large scales in many European countries. In India, it is produced in Tamil Nadu, Maharashtra and Kerala states. Preparation: Livers removed
