Cortex Acanthopanacis Senticosi, alias Cortex Acanthopanacis Senticosi, Cortex Acanthopanacis Senticosi, Cortex Acanthopanacis Senticosi and Acanthopanax sessiliflorus, is the dried root bark of Acanthopanax senticosus, Acanthopanax senticosus, Acanthopanax scabra and Acanthopanax sessiliflorus. It is a commonly used Chinese herbal medicine. The bark of wild or cultivated acanthopanax root is processed into medicine.

Second, the morphological characteristics

At present, there are usually three kinds of acanthopanax bark used in various parts of China. ?

? 1, acanthopanax gracilis. Deciduous shrubs, sometimes trailing, 2-3 meters high. The stem is erect or climbing, the branches are grayish brown, with obvious lenticels, and the trunk often has short and thick long curved thorns. Palmately compound leaves 3-5, alternate, or clustered on short branches. The petiole is slender and spiny. Leaflets obovate or lanceolate, 3-8 cm long and 1-3.5 cm wide. The apex is tapered, the base is wedge-shaped, the edge is obtuse and serrated, the upper part is dark green, the veins and edges are bristly, and the lower part is light green with small barbs. Yellow-green flowers bloom in summer and autumn, and umbels 1-2 are axillary or born at the ends of branches; There are 5 teeth on the edge of calyx, 5 petals, 5 stamens, lower ovary, filiform style, separation and development. Berries are nearly spherical and purple-black when ripe. ?

? 2. Acanthopanax sessiliflorus. The morphology of Acanthopanax gracilishaeformis is similar to that of Acanthopanax gracilishaeformis, and the obvious difference is that the compound leaves of Acanthopanax gracilishaeformis are mostly 3 leaflets, and the leaves are larger, up to 15 cm. The inflorescence is densely head-shaped, with one or several clustered branches at the top, dark purple-brown flowers and no small pedicels. Berries are oval and larger. ?

? 3. Acanthopanax giraldii. Deciduous shrub, height1-3m. Old branches are gray, spineless or spiny, and new branches are gray-brown or yellow-brown. Dense slender brown-red needles, the needles are downward or flat. Palmately compound leaves with 5 leaflets and slender stalks; Leaflets obovate or oblong. Small white flowers bloom in early autumn, umbels are at the top of branches, and the total pedicels are thick and short; Calyx nearly entire, ovary 5-loculed, with 5 styles, united at the base and separated at the upper part. The fruit is spherical and black when ripe.

? Third, harvesting and processing?

? 1, harvesting: harvesting in autumn. When harvesting, cut off the stems and leaves on the ground and dig out the roots. Shake off the soil, remove the fibrous roots, wash, peel off the root bark, take out the wood core, spread it out in the sun to dry, and put it into sacks or woven bags. This product is easy to change color when it is wet, so it should be placed in a ventilated and dry place. Pay attention to mildew prevention and moth prevention. A small amount can be put into the cylinder, sealed against moisture, insects, mildew and fragrance loss. ?

? 2. Processing: Acanthopanax senticosus is divided into three types: raw processing, wine frying and ginger processing.

Raw use: Wash Cortex Acanthopanacis Senticosi with water, pick up the bone core, cut it into 6 mm long, dry it in the sun or with slow fire, and sift out the dust. Stir-frying with wine: according to the ratio of 50 grams of white wine 15 grams, stir-fry raw acanthopanax bark in a pot, pour the wine in several times, stir-fry until all the wine is absorbed, take it out and cool it.

Ginger processing: according to the ratio of ginger10-15g for every 50g of acanthopanax bark, first mash ginger, add a little water, and remove residue. Then put Cortex Acanthopanacis Senticosi into a pot, stir-fry on slow fire, add ginger juice, stir-fry until all ginger juice is absorbed, and take it out. ?

? 4. Commodity characteristics and specifications?

? 1, commodity characteristics. Commodities are long cylindrical, mostly double-rolled. The outer skin is grayish brown, with longitudinal grooves slightly twisted in the longitudinal direction and transverse oblong lenticels, and the inner surface is yellow with longitudinal stripes, which is light and brittle and easy to break. Irregular section, grayish yellow or grayish white. Slightly fragrant, bitter and astringent.

Acanthopanax giraldii: it is slender and tubular. The outer surface is yellow, densely covered with brown or yellowish bristles, and some are reddish brown, mostly leaning to one side, with a few raised bud marks; The inner surface is yellow-green or yellow-brown, smooth. The skin is thin, brittle and easy to break. Slightly fragrant and pungent.

2. Commodity specifications. The material specifications of commercial drugs are generally uniform goods: dry goods, irregular cylindrical, with grayish brown outer surface, twisted wrinkles and long round lenticels, grayish yellow inner surface, light weight and grayish yellow cross section. The smell is fragrant, the taste is pungent and bitter. Regardless of length and thickness. No impurities and mildew.

Acanthopanax giraldii (Acanthopanax giraldii): unified goods: dry goods, in a slender tube shape, with a grayish brown appearance, densely covered with brown or yellowish bristles, and slightly reddish brown. The inner surface is yellow-green or brown, smooth, thin and crisp, slightly fragrant and pungent. Regardless of length, there is no impurity, no sediment and no mildew.
