source
Source of medicinal materials: dry bark, root bark and branch bark of Magnolia officinalis in Orchidaceae.
Latin plant and animal mineral names: Magnolia
Harvest and storage: picking fruits from April to June. Root bark and branch bark are directly dried in the shade; After slightly boiling in boiling water, the dried skin is piled in a damp place and sweated until the inner surface turns purple-brown and yellow-soft. Take it out, roll it into a tube and dry it. Store in a dry container, sealed and placed in a cool and dry place.
Deciduous trees in primitive form, up to 24 meters high. The bark is light gray. Branchlets are stout, green when they are young, then brown, with cylindrical buds and grayish green; 5-9 leaves clustered at the top of the stem; The petiole is stout, 4-7 cm long, and the stipules are obviously raised, which is about two-thirds of the petiole length; Leaf blade papery, obovate or oblong obovate, 30-50 cm long, 20-25 cm wide, entire, wide and round at the top, short and sharp, slightly heart-shaped at the base, green and shiny at the top, pale at the bottom, covered with brown hair, with 28-30 pairs of veins. Leaves open after flowering, fragrant and big; Perianth 9- 12, 3 outer wheels, green back, slightly pink abdomen, rolled outward, white inner wheel; Stamens purplish red, connective protruding into triangular tip; The gynoecium is cylindrical. Aggregate fruit is cylindrical, with a length of 1 1- 18cm. The top of the capsule bends outward, and the beak is 6-8 mm long. Seeds flat, ca. 7 mm long. The flowering period is April-May, and the fruiting period is 9-65438+1October.

Character identification: the dry skin is rolled, with a thickness of 0.4- 1.5cm, and the outer surface is grayish yellow, nearly smooth, with transverse oval or quasi-circular lenticels; The inner surface is dark brown, nearly smooth, with fine longitudinal lines and slightly oily nails. Hard and not easy to break. The cross section is fibrous, with a large number of white crystal particles, which shine on light. It is fragrant, spicy and slightly bitter. The root bark is irregular and usually curved. Hard, the section is rich in fiber. Branches and bark are mostly single tubular, thin and brittle.
Microscopic identification of dry bark cross section: 2-8 rows of cork cells in cork layer, wall thickness, lignification; The inner layer of suppository is a stone cell ring, with square stone cells, thick wall, solid wood and obvious holes and grooves. The cortex is broad, scattered in stone cells, single or in groups, rectangular, polygonal or irregular, with thick walls, solid wood and clear holes, grooves and layers; There are many oil cells with yellow oil droplets; Fiber groups are sparsely arranged. The phloem accounts for the vast majority, and phloem rays 1-3 rows of cells; Fiber groups are alternately arranged with sieve tubes and parenchyma cells; There are some stone cells; Oil cells can be seen everywhere. The parenchyma cells of this product contain starch granules and calcium oxalate crystals.
Physical and chemical identification TLC: 1 Take 1g powder, put it in 100ml test tube with stopper, add 5ml ether, soak for 4 hours, and concentrate to 0.3ml as test solution; In addition, magnolol, honokiol and β -cineole were used as reference substances. Samples were respectively spotted on the same 0.5%CMC silica gel G plate, developed with cyclohexane-chloroform-absolute ethanol (7: 3: 1), detected by ultraviolet lamp (254nm), and the same fluorescent spots as magnolol and honokiol were displayed in the chromatogram of the sample. When sprayed with 5% vanillin concentrated sulfuric acid, the same color spot appeared at the corresponding position of β-cineole, and the color was quite dark after heating at 100℃, while magnolol and honokiol hardly developed at the corresponding position. 2 Take 65438 0 g of this product powder, add 5ml of ethanol, soak for 24 hours, and concentrate the extract to 0.3ml as the test solution; In addition, brucine, magnolipin and willow magnolipin were used as control substances. The samples were placed on the same 0.5%CMC silica gel G, and developed with ethyl acetate-ethyl ketone-formic acid-water (5: 3: 1: 1), and developed with improved sulfonated bismuth potassium. In the chromatogram of the sample, the same spots were found at the corresponding positions of magnolol and magnolol.
The quality label "Drug Standard of People's Republic of China (PRC) and Drug Standard of the Ministry of Health of the People's Republic of China" (Volume I) 199 1 version stipulates that the total content of magnolol and honokiol in this product shall not be less than 2.0% in terms of dry product.
Chemical composition: bark contains honokiol, honokiol, honokiol and volatile oil, and the oil contains β -eucalyptol (β-eude *** ol).
Prepare herbs by frying.
1. Yunpu takes the original medicinal materials, washes them, spreads them flat, scrapes off rough skin, shreds them and dries them.
2. Take Yunpusi from Jiang Yun, add ginger juice and mix well, fully moisten it, put it in a pot, heat it with slow fire, fry it dry, take it out and let it cool. 100 kg per shop, with 20 kg of ginger. Characteristics of the decoction pieces: Yunpu is filiform and 2-3mm wide. See the identification item of medicinal materials for details. Jiang Yunpu looks like a cloud, with a darker color and a slightly spicy smell of ginger.
