(2) take the crude powder 1g of this product, add chloroform 10ml, plug, perform ultrasonic treatment for 30min, filter, evaporate the filtrate, and add the residue.
Dissolve 2ml chloroform as test solution. In addition, taking the magnolin reference substance, adding methanol to prepare a solution containing 1mg per 1ml,
As a reference solution. According to the test of thin layer chromatography (appendix ⅵ b), absorb 2 ~10 μ l of the above two solutions, respectively.
Dotted on the same silica gel H thin-layer plate with sodium carboxymethyl cellulose as adhesive, and chloroform-ether (5:1) as developing agent,
Spread, take out, air dry, spray with10% sulfuric acid ethanol solution, and heat at 90℃ until the spots are clear. In the test sample chromatography, in
At the position corresponding to the chromatogram of the reference substance, the same purple-red spots are displayed.
Content determination
The volatile oil was determined according to the volatile oil determination method (appendix ⅹ d). The volatile oil content of this product shall not be less than1.0% (ml/g).
Magnoliacin was determined by high performance liquid chromatography (Appendix ⅵ d).
Octyl bonded silica gel was used as filler for chromatographic conditions and system applicability test. Acetonitrile-tetrahydrofuran-water (35: 1:64) was the mobile phase; The detection wavelength is 278nm. The theoretical plate number should be no less than 9000 according to the magnolin peak.
Preparation of reference substance solution: Accurately weigh an appropriate amount of magnolipin reference substance dried to constant weight under reduced pressure at 60℃, and add methanol to make a solution containing 0. 1mg of magnolipin per 1ml, thus obtaining the product.
Preparation of test solution Take the coarse powder of this product about 1g, weigh it accurately, put it in a conical flask with a stopper, add 20ml of ethyl acetate accurately, weigh it, soak it for 30 minutes, perform ultrasonic treatment (power 250W, frequency 33 kHz) for 30 minutes, let it cool, weigh it again, make up the lost weight with methanol, shake it evenly, filter it, and measure it accurately. Add it to a neutral alumina column (100 ~ 200 mesh, 2g, with an inner diameter of 9mm, packed in the column by wet method, and pre-washed with 5ml of ethyl acetate), elute with methanol 15ml, collect the eluate, and put it in 25ml.
In the bottle, add methanol to the scale, shake well, and filter with microporous membrane (0.45μm).
The determination method accurately sucks 4 ~10 μ l of the reference solution and the test solution respectively, and injects them into the liquid chromatograph for determination, thus obtaining the product.
This product contains no less than 0.40% of magnolin (C23H28O7) calculated as dry product.
Sexual taste is pungent and warm. Enter the lung and stomach meridians.
Functions are mainly used to dispel cold and dredge nasal orifices. Used for wind-cold headache, stuffy nose, deep nose, and turbid nose.
Usage and dosage 3 ~ 9g; Appropriate amount for external use.
Store in a cool and dry place.
remarks
(1) There are several kinds of flower buds of the same genus that are also used as medicine in different areas: magnolia liliflora desr. [M. quinquepeta (buc' hoz) dandy]; Magnolia divastapf [m. Denudata desr. var. Purpura scenes rehd. et wils.]; Magnolia campbell ii hook.f.et thoms.; Magnolia grandiflora L.
(2) This product enters the lung meridian and passes through the nose to dispel cold, so it is clinically used to treat nasal sinusitis with turbid nasal discharge and no smell, and is often combined with Radix Angelicae Dahuricae, Herba Asari, Radix Saposhnikoviae and Fructus Xanthii.
