Sheng Xiangfu ÉúÏ㸽 Xiangfu Mi Ï㸽Ã× Xiangfu Zi Ï㸽×Ó Zhi Xiangfu ÖÆÏ㸽 Chinese Name (pinyin): Xiangfu

Chinese Name  :

Common Name  :Nutgrass Flatsedge Rhizome

Specific Name  : Rhizoma cyperi

Scientific Name:
Collection  : The drug is collected in autumn, boiled briefly after the fibrous matter is burnt off or steamed thoroughly and dried in the sun or dried in the sun directly after the fibrous matter burnt off.

Description  : Frequently fusiform, some somewhat curved, 2 - 3.5 cm long, 0.5 - 1cm in diameter. Externally dark brown, longitudinally wrinkled and with 6 - 10 slightly prominent, annular nodes with brown fibrous matter and remaining root scars or slightly smooth and exhibiting indistinct annular nodes with the fibrous matter completely removed. Texture hard, fracture hard, fracture or steamed rhizomes appearing yellowish brown or reddish brown, horny. Fracture of the un-steamed ones white and starchy, endodermis ring obvious, stele darkened in colour with scattered dotted vascular bundles. Odour aromatic, taste slightly bitter.

Identification  : 1.Powder: Pale brown, secretory cells, subrounded, 35 - 72 µm in diameter, containing yellowish brown to reddish brown secretion with adjacent 5 - 8 cells arranged in radiate ring. Epidermal cells polygonal frequently with hypodermal fibre bundles and sclerenchymatous cells. Hypodermal fibres bundles dark brown or reddish brown, 7 - 22 µm in diameter, walls thickened, sclerenchymatous cells subsquare, subrounded or irregular, walls slightly thickened with pits. Stone cells rare subsquare, subrounded or sub polygonal, walls relatively thickened.2.Macerate 1 g of the powder in 5 ml of ether for 1 hour with constant shaking, filter and evaporate the filtrate to dryness. Dissolve the residue in 0.5 ml of ethyl acetate as the test solution. Dissolve a=cyperone CRS in ethyl acetate to produced a solution containing 1 mg per ml as the reference solution. Carry out the method for thin layer chromatography (Appendix Vl B) using silica gel GF254 as the coating substances and benzene-ethyl acetate-glacial acetic acid (92:5:5) as the mobile phase. Apply separately to the plate each of 5 µl of the two solutions. After developing and removal of the plate, dry it in the air and examine under an ultra violet light (254 nm). The dark blue spot in the chromatogram obtained with the test solution corresponds in position and colour to the spot in the chromatogram obtained with the reference solution. Then spray with 2,4-dinitrophenyl hydrazine TS, the colour of the spot turns to orange red gradually on standing.Total ash: Not more than 4.0 %

Processing  : Remove fibrous matter and foreign matter, pound to pieces or cut into thin slices.Processed with vinegar: Stir fry the pieces or slices of Rhizoma Cyperi as described under the method for stir frying with vinegar (Appendix ll D) to dryness.

Action  : To remove stgnation of qi, regulate menstruation and relieve pain.

Indication  : stagnation of the liver qi characterized by distending pain in the chest, hypochondria and epigastrium, indigestion, feeling of stuffiness in the chest and epigastrium, abdominal colic, distending pain in the breast, menstrual disorders, amenorrhea, dysmenorrhea

Precautions  :

Dosage  : 6 to 9 g.

Storage  : Preserve in a cool and dry place, protected from moth.
