Introduction for Portulaca oleracea extract

Portulaca oleracea extract is a one-year-old herb of the genus Purslane, which is used for both medicine and food. Modern research has shown that purslane is not only rich in nutrients, but also contains a variety of active substances, including alkaloids, flavonoids (also known as flavonoids), polysaccharides, sterols, organic acids, glycosides, Phenolic compounds, oils and other ingredients. It is the more active ingredients contained in the purslane, which has various active functions, especially the flavonoids in the active ingredients, which have strong antibacterial, anti-oxidant and anti-cancer effects. Function, so there is a certain need for development and utilization.


Extraction Process Design

The test design for Portulaca oleracea extract was carried out using Box - Behnken. The ethanol concentration/% (A), ultrasonic time/min (B), temperature °C (C) were used as independent variables, and the total flavonoid yield Y was the response value. The response surface was analyzed by desinger expert software. The optimal extraction process conditions are: ethanol concentration 77. 82%, ultrasonic time 36. 72min, temperature 37. 79 ° C, the theoretical yield is 21. 8816 mg / g. The inadequacy is that the extraction rate of flavonoids is higher. The reason for this analysis is that ethanol is used as the extractant in this experiment. The polarity of ethanol is large, and the components such as chlorophyll are extracted, which results in a larger absorbance value. Therefore, the calculated total flavonoids of purslane are too large.Portulaca oleracea extract.jpg


The Portulaca oleracea extract have certain inhibitory effects on Escherichia coli, Staphylococcus aureus and yeast, and have strong inhibitory effects on Escherichia coli and yeast. The minimum inhibitory concentration is 0. 313mg/mL; the strongest inhibitory effect on Staphylococcus aureus, the minimum inhibitory concentration is 0. 156 mg/mL.
