Abstract:
A method of preparing pharmaceutical moxa extract tincture formulation, comprising the steps of:extracting a moxa-methanol extract by extracting from the dried young leaves of Artemisia with methanol and condensing the extract;extracting a moxa-dichloromethane fraction by suspending the condensed moxa-methanol extract in water, mixing the suspended extract with dichloromethane, distilling the mixture in a fractional distiller, and collecting the moxa-dichloromethane fraction from the lower portion of the fractional distiller with an uncollected portion remaining;extracting a moxa-ethylacetate fraction by adding ethylacetate to the uncollected portion, distilling the resultant mixture in a fractional distiller, and collecting the moxa-ethylacetate fraction from the upper portion of the fractional distiller;obtaining a dried mixture by mixing the moxa-dichloromethane fraction and the moxa-ethylacetate fraction, condensing the mixture and evaporating the condensed mixture; anddiluting the dried mixture with an amount of ethanol 2-5 times relative to the weight of the dried mixture.
