Optimized extraction process for obtaining labisia pumila extract

摘要

The present invention relates to a process for obtaining a Labisia pumila water extract comprising the steps of: obtaining an extract from dried Labisia pumila plant material using water extraction, filtering the extract to obtain filtrate and Labisia pumila plant material residue, re-extracting the Labisia pumila residue using water extraction, centrifuging the Labisia pumila extracts to obtain a supernatant, characterized in that, the Labisia pumila plant material includes leaves and roots in a ratio of 3:2 by weight and ratio of the dried plant material to water used in the water extraction process is 1:10 by weight, wherein the yield obtained from initial extraction is 7% to 8% and the extra yield obtained from re-extraction is 33% to 38% and the total yield obtained from the extraction is 10% to 12%.
