    Kindly avail me what should be the best methods and why"

    You are fortunate to have one of the best Artemisia experts in Uganda, Pr Patrick Ogwang from the Makerere university.
    He has published several scientific papers on this subject.
    You may contact him at pe7321@gmail.com or patrickengeu@gmail.com
    He has also developed the prophylactic product ARTAVOL

    That is a very interesting article. As an expert on extraction and purification of artemisinin, I allow myself to give some scientific explanations to the fact that the presence of bicarbonate salts enhances extraction.
    First why boiling water gives more artemisinin, this is a causal effect not a direct one; artemisinin is dissolved in essential oil ducts present in the leaves, high temperature of boiling water enhances solubility of essential oil in it which in turn entrain artemisinin in water.
    Addition of bicarbonates will cause dehydration of cell ducts by an osmose like effect, so ducts will dry then explode to release their content, so we will have more artemisinin and co-metabolites in the bulk medium. Although most artemisinin analogs present in the leaves have antimalarial activity but the main driver here is Artemisinin. Nonetheless, the synergy effect is definitely here.
    Thanks
