The invention relates to the technical field of
traditional Chinese medicine preparations, in particular to a
polysaccharide extraction method, a Qi-II ointment formula capable of invigorating the
spleen, replenishing Qi, enhancing
immunity and resisting fatigue and a preparation method of the Qi-II ointment formula. The paste is prepared from
astragalus membranaceus,
codonopsis pilosula, Chinese yam, poria cocos,
lotus seeds, rhizoma polygonati, red dates,
coix seeds, lily, liquorice and
fructus psoraleae as raw materials through the processes of
raw material pretreatment,
water extraction-
alcohol extraction synergistic extraction, beta-
cyclodextrin inclusion and concentration paste collection, sterilization and filling. Wherein L-
tartaric acid is adopted to regulate the pH value of an extracting solution, and
polysaccharide is promoted to be directionally degraded into low-molecular active fragments; bitter and
astringent taste of
saponin components is masked by using a beta-
cyclodextrin inclusion technology, the taste is improved, and the
bioavailability is improved; and the product stability is enhanced through combination of vacuum
dehydration and dynamic sterilization. The cream has the functions of invigorating
spleen, replenishing qi, regulating
immunity and resisting fatigue, is sweet and moist in taste and high in safety, and has a wide application prospect.
