Embodiment 1
[0179] Aerial parts of Caralluma fimbriata plants were collected and dried in the open air in the shade at 310. The dried material is ground in a rotary hammer mill 320 . For the extraction step 330, approximately 500 kg of this dry powder material is loaded into the extractor. The extractor consisted of a stainless steel tube of approximately 5000 liter capacity equipped with a stirring system and a surrounding jacket for steam heating. About 2000 liters of about 30% ethanol in water were loaded into the extractor. The loaded solvent was formed by mixing about 600 liters of rectified alcohol with about 1400 liters of water. The extractor contents were maintained at about 70-75°C by steam heating and the extraction process was carried out for about 6 hours. This extract is referred to as Extract "A". Extract "A" had a volume of about 1500 liters.
[0180] A second extraction (leaching) operation is performed on the residue in the extractor containing partially extracted b...
Embodiment 2
[0188] Starting from the product of Example 1, the buffalo plant extract product of the present invention in solid form was prepared.
[0189] About 60 kg of the product obtained in Example 1 was mixed with the required amount of maltodextrin, starch and gum arabic in a blender and stirred for about 30 minutes to obtain a homogenized substance (step 410).
[0190] The homogenized mass was dried in a tray drier. The material is spread in a thin layer on stainless steel trays in a desiccator and dried at about 60°C (step 420).
[0191] The dry product from the above steps is pulverized by eg a micronizer (step 430) and then sieved in an S.S. sieve to a particle size of about 40-80 mesh (step 440). The sieved material is blended in a double-cone blender for about 1 hour to obtain a homogeneous powder (step 450).
[0192] The uniform powder is the second type of buffalo plant extract product described in the present invention. The above procedure was repeated 5 times. The anal...
Embodiment 3
[0196] Same procedure as described in Example 2 with the following differences. In Example 3, drying was performed in a spray dryer instead of a tray dryer, and the homogenized material was dissolved in water as required for the spray dryer charge. A minimum amount of water is used.
[0197] The spray-dried buffalo extract was found to be finer and more uniform in size, and thus the optional powdering and sieving steps did not need to be performed.
