A Caralluma extract and a method of making thereof which can be
standardized and reproducible, and which prevents the glycosides from
decomposition, which can reduce the undesirable non-glycoside components.
In the first Caralluma extract, the resinous material does not exceed
0.5% by weight, and, in the second Caralluma extract, the resinous
material does not exceed 1.0% by weight. The first extract is produced by
optionally pretreatment of plant materials, optional crushing and/or
grinding, extraction, and concentration. The filtration step and the
resin removal step may be performed optionally. The second extract is
produced by contacting the first Caralluma extract with excipients,
drying, powdering, sifting and blending. The Caralluma extracts of the
present invention can be used for medical purposes and as food additives.
