摘要:
An extract from green coffee beans is disclosed which contains polyphenols and bioactive compounds e.g. Chlorogenic acids in a significantly higher concentration (70-80%) than in extracts of prior art methods (40-50%). The extract has greater ability to quench oxidative stress and destroy free radicals and offers health benefits due to its anti-obesity, anti-diabetic, antihypertensive, anti-tumor and anti-acid properties. The higher concentration of bioactive compounds has been achieved by use of polar solvents having polarity less than that of alcohols used for extraction. The use of such solvents of lower polarity such as n-Butyl alcohol, ethyl acetate or acetone results in extraction of enriched Chlorogenic acid fractions into the extract, leaving polar impurities behind in aqueous medium. The extract obtained has significantly higher content of polyphenols and chlorogenic acids ranging from 70-80% and a distinctive HPLC profile.

摘要:
A novel, commercially viable process for the extraction of high purity (>70%), bioactive furostanolic saponins including protodioscin (>30%), from the seeds of fenugreek (Trigonella foenumgraecum) comprising essentially the steps of powdering of the natural material followed by a first extraction, an ion-exchange chromatographic purification and a second extraction using a novel composite solvent and drying of the product under defined conditions, the entire process being carried out at essentially neutral pH and low temperatures of less than 80° C.
摘要:
The present invention discloses a novel anti-diabetic composition extracted from fenugreek seeds. The same comprises a furostanolic-saponin-rich fraction (>70%) with approximately 30% protodioscin as one of the bioactive components. Pre-clinical studies in rats indicated significant glucose lowering effect of the fraction (31.5%) as compared to control after two weeks of oral treatment. Clinical studies in human volunteers indicated suitability of a dosage form of 500 mg given once or twice daily as anti-diabetic agent either alone or in combination with standard, synthetic anti-diabetic drugs such as metformin and glipizide in controlling plasma glucose levels.

摘要:
Present invention discloses a novel, commercially viable process for extraction of Alpha yohimbine from the bark, stem and leaves of Rauwolfia species. The extract is obtained by a precipitation method involving alternate steps of acidification and alkalization along with use of specific organic solvents. The extract gives higher yield of 7-8 fold as compared to other processes and without use of any column chromatography at all. Yield of alpha yohimbine from roots and leaves of Rauwolfia canescens by process of present invention was 0.017% and 0.4% respectively, indicating that leaves are a much better source. The HPLC analysis of the compound obtained indicated a purity of >90%.

摘要:
Disclosed is an extract obtained by a commercially viable process for the extraction of furostanolic saponins from fenugreek seeds, in which one of the compounds in the extract is protodioscin. The process includes providing plurality of fenugreek seeds and crushing the same by milling and grinding; performing a primary extraction on the prepared fenugreek seeds using a first hydrophilic polar solvent which is a lower primary aliphatic alcohol followed by ion-exchange chromatography; performing a secondary extraction after ion-exchange chromatography using a composite solvent; and decolorizing the final extract by use of activated charcoal concentration of the extract by heating and vacuum drying sieving the final powdered product.
