Overview
Trachycarpus Petiole is the dried petiole of Trachycarpus fortunei (Hook. f.) H. Wendl. (Fam. Palmae). The drug is collected by cutting off the lower part of the old petiole and sheath of the leaf, removing fibrous brown hairs, and drying in the sun.
Description
Trachycarpus Petiole is long and plate-like, with one end narrower and thicker, and the other end wider and slightly thinner, varying in size. The surface is reddish-brown, rough, with longitudinal and vertical wrinkles; one side has obvious protruding fibers, and both sides of the fibers are covered with brownish hairs. The texture is hard and tough, not easily broken, and the fracture is fibrous. It has a slight odor and a mild taste.
Identification
（1）The powder of this product is reddish-brown to brownish-brown. The fibers are bundled, slender, with a diameter of 12-15μm. The thin-walled cells on the outer side of the fibers contain small clusters of calcium oxalate, forming crystal fibers. The stomata are straight or indefinite, with 5-6 subsidiary cells. Tracheids with reticulate, spiral, and ladder-like wall thickenings can be seen.
（2）Take 1g of the powder, add 20ml of water, heat for 5 minutes, filter, and dilute the filtrate with water to 20ml. Take 1ml of the filtrate, add 2-3 drops of ferric chloride test solution, and a dirty green flocculent precipitate is formed; take another 1ml of the filtrate, add 3 drops of sodium chloride gelatin test solution, and a white turbidity appears.
Prepared slices

Trachycarpus Petiole (carbonized)
Processing
Carbonize the clean Trachycarpus Petiole as described under the method for carbonizing by calcining <0213>.
Description
Irregular pieces, varying in size. Externally dark brown to black, lusterous, with longitudinal wrinkles; when toughing, black toner in hand. Internal coke yellow, fibrous. Odour, burnt aromatic; taste, bitter and astringent.
Identification
（1）Powder: Black brown. Fibres bundled, black brown, surrounded with parenchymatous cells containing prisms of calcium oxalate, forming crystal fibres. Scalariform vessels are about 25 µm in diameters.
（2）To 5g of the powder, add 50ml of methanol, ultrasonicate for 20 minutes, filter, evaporate the filtrate to dryness. Dissolve the residue in 1ml of methanol, as the test solution. Dissolvel Protocatechuic aldehyde CRS and Protocatechuic acid CRS in methanol to produce a solution containing 0.2mg of each per ml as the reference solution. Carry out the method for thin layer chromatography <0502>, using silica gel G as the coating substance and a mixture of chloroform, n-butanol and glacial acetic acid (20 : 1 : 1) as the mobile phase. Apply separately 5µl of each of the above two solutions to the plate. After developing and removal of the plate, dry in air. Spray with ferric chloride TS. The dark-green spots in the chromatogram obtained with the test solution correspond in position and colour to the spots in the chromatogram obtained with the reference solution.
Property
Neutral.
Flavor
Bitter and astringent.
Meridian tropism
Lung, liver, and large intestine meridians.
Actions
To astringe and stop bleeding.
Indications
Used for vomiting blood, nosebleed, hematuria, bloody stool, and metrorrhagia and metrostaxis.
Dosage
3-9g.
