Purslane (Portulaca oleracea L.) is a weed that can be used as a source of natural antioxidants. One of the ingredients in purslane is ascorbic acid (vitamin C). One of the preventive measures related to infections caused by the corona virus is taking vitamin C to support the body’s immunity which is proven to have a positive effect on the body’s immunity. Vitamin C can prevent susceptibility to reduce respiratory infections in certain conditions. COVID-19 has been reported to cause higher respiratory infections so vitamin C can be an effective choice for COVID-19 treatment.
Method: taking purslane planting material in the lowlands <200 m asl Surabaya, medium plains 200-800 m asl in Malang DAU and uplands> 800 m asl Batu. Poor. Vitamin C analysis was carried out using HPLC
Results: The analysis of the content of Portulaca oleracea L. Ascorbic acid (Vitamin C) from three heights was at plateau 9.24 mg / kg, medium plain 2.40 mg / kg and lowland 9.73 mg / kg.
