The invention discloses a novel method for extracting and concentrating efficient components of a
kidney-tonifying Juanbi
pill, which comprises the following steps: pretreating medicinal materials: taking prescription medicinal materials of the
kidney-tonifying Juanbi
pill; the
traditional Chinese medicine composition is prepared from rhizoma drynariae, prepared
rehmannia root, Chinese angelica, paniculate swallowwort root,
ground beetle, stiff silkworm (stir-fried with
bran),
centipede, scorpio,
honeycomb (stir-fried with clear water),
lumbricus (processed with
wine), zaocys dhumnade (processed with
wine),
corydalis tuber,
pyrola,
epimedium, berba aristolochiae mollissimae,
geranium wilfordii, caulis spatholobi, scandent hop, radix rehmanniae recen and
polygonum cuspidatum. Through targeted medicinal material pretreatment and ultrasonic-assisted extraction, the problems of slow
dissolution of
plant medicinal effective components and difficult extraction of animal medicinal
cuticle of the
kidney-tonifying Juanbi
pill are effectively solved, and the extraction rate of the medicinal effective components stably reaches 60% or above. Effective components of medicinal materials such as
polygonum cuspidatum, caulis spatholobi, berba aristolochiae mollissimae,
geranium wilfordii and
rehmannia in the prescription can be fully dissolved out, and waste of raw materials is avoided.
