TH18683U - Methods for extracting substances from cashew leaves. - Google Patents

Abstract

------24/09/2563------(OCR) The process of extracting substances from cashew leaves begins by drying cashew leaves at a temperature of 45-60 degrees Celsius. Then, the dried cashew leaves are extracted with 50% alcohol. The entire mixture is then evaporated using a rotary evaporator at a temperature of 50-55 degrees Celsius. The mixture is then filtered and frozen. The resulting cashew leaf extract has an antioxidant activity of 0.87-1.39% as measured by the DPPH method and an antioxidant activity of 0.84-0.90 µg ascorbic acid (mg. extract) as measured by the FRAP method. ------------ Page 1 of 1. Abstract of the Invention: The product contains a mixture of cashew leaf extract and dietary fiber. The dietary fiber is obtained from the extraction of cashew fruit pulp. It was found that the antioxidant activity using the DPPH method was 7.76-8.66%, and the antioxidant activity using the FRAP method was 14.52-14.74 mcg of ascorbic acid (mg. extract). The percentage of inhibition of alpha-amylase, alpha-glucosidase, and aldose reductase enzymes was 31.07-31.37, 0.89-1.03, and 3.05-3.31%, respectively. The percentage of anti-inflammatory activity by inhibiting cyclooxygenase-2 was 6.90-7.52%.

Claims (5)

------24/09/2563------(OCR) 1. The process for extracting substances from cashew leaves is as follows: - First, cashew leaves are cut into pieces and dried at a temperature of 45-60 degrees Celsius for 12-24 hours. - Then, the dried cashew leaves are extracted with 50% alcohol, using a ratio of dried cashew leaves to 50% alcohol of 1:10. - The entire mixture is then evaporated using a rotary evaporator at a temperature of 50-55 degrees Celsius. - Finally, the mixture is filtered and frozen for 12-24 hours. 2. The process for extracting substances from cashew leaves, as per claim 1, where 50% alcohol can be replaced with either water or 95% alcohol. ------------ Page 1 of 1 page Claims 1. Products containing cashew extract include 1-50% cashew extract by weight and 50-99% cashew nut meal by weight. 2. Products containing cashew extract, as per claim 1, where the most suitable cashew extract is derived from the leaves of the cashew tree. 3. Products containing cashew extract as per claim 1 or 2, where the cashew extract extraction process involves the following steps: - Cashew leaves are cut into pieces and dried at 45-60°C for 12-24 hours. - The dried cashew leaves are then extracted with 50% alcohol using a ratio of 1:10. - The mixture is then evaporated using a rotary evaporator at 50-55°C. - The mixture is then filtered and frozen for 12-24 hours. 4. Products containing cashew extract, as per claim 3, where 50% alcohol can be replaced by either water or 95% alcohol. 5. Products containing cashew extract, as per any one of claims 1-4, where the preparation process of cashew fruit pulp involves the following steps: - First, cashew nuts are cleaned and cut into pieces. Then, the juice is extracted from the cashew nuts. - The extracted cashew nuts are mixed with water in an amount that makes the total pH of the mixture equal to 4-6. - The mixture is then boiled at 60-80 degrees Celsius for 90-150 minutes and then allowed to cool. - The mixture is then fermented in 95% alcohol for 36-48 hours. - The fermented mixture is then baked at 30-65 degrees Celsius for 12-24 hours. Finally, the baked mixture is ground into a fine powder to obtain cashew fruit pulp.
