Abstract

The extraction process for active compounds from sea morning glory leaves begins by drying the leaves and then grinding them into a fine powder. This powder is then extracted with clean or distilled water by boiling at 80 degrees Celsius, and filtered through cheesecloth. The resulting extract is then spray-dried. This yields a sea morning glory extract with a high concentration of active compounds, which can be used to prepare pharmaceutical products, dietary supplements, and beverages.

OCR 09WP 20/12/2567 1. The extraction process for active compounds from Ipomoea pes-caproe leaves consists of the following steps: a. Wash the leaves and vines of Ipomoea pes-caproe (L.) R. Br. to remove soil, sand, and insects. Then air-dry them at room temperature. Next, cut the leaves into small pieces and dry them in an oven at 40-60°C for 12-48 hours, or until crispy. After drying, grind the pieces finely and sieve them through a 1-10 mm mesh. b. Extract the compounds from the leaves and vines from step a using a 1:10 ratio with water or distilled water. Boil the mixture at 70-80°C for 2 hours, then filter it through cheesecloth. A leaf and vine extract of Ipomoea aquatica with a concentration of 4% Brix was obtained. The Ipomoea aquatica extract obtained from step B was then evaporated using a spray dryer at an inlet hot air temperature of 130-150°C and an outlet temperature of 70-90°C, an atomizer speed of 9,000-11,000 rpm, and a feed rate of 0.2-1 bar. The resulting extract was a brown or dark brown powder.
