Pseudostellaria heterophylla

Background

Haiershen º¢¶ù²Î Tongzishen ͯ×ӲΠChinese Name (pinyin): Taizishen

Chinese Name  :

Common Name  :Pseudostellaria Root

Specific Name  : Radix pseudostellariae

Scientific Name:
Collection  : The drug is collected in autumn when the stem and leaves are mostly withered, wash clean, removed from rootlet. Either treated with boiling water for a moment and dried in the sun or dried in the sun directly.

Description  : Slenderly fusiform or slat shaped, slightly curved, 3 - 10 cm long, 2 - 6 mm in diameter. Root stock marked with stem scars. Externally yellowish white, relatively smooth but slightly wrinkled longitudinally with rootlet scars at a dent. Texture hard and fragile, fracture even, yellowish white and horny or whitish and starchy. Odour slight, taste sweetish.

Identification  : 1.Transverse section: Cork consisting of 2 - 4 rows of subsquare cells. Cortex thin only consisting of several rows of parenchymatous cells, elongated tangentially. Phloem narrow with broad rays. Cambium in a ring. The majority of root occupied by xylem, vessels sparse and arranged radially, primary xylem occurring triarch to tetriarch. Parenchymatous cells packed with starch granules and clusters of calcium oxalate.2.Macerate warmly 1 g of the powder in 10 ml of methanol, shake for 30 minutes, filter. Use filtrate as the test solution. Prepare a solution of Radix Pseudostillaria reference drug in the same manner as the reference drug solution. Carry out the method for thin layer chromatography (Appendix Vl B) using silica gel G containing sodium carboxymethyl cellulose as the coating substance and n-butanol-glacial acetic acid-water (4:1:1) as the mobile phase. Apply separately 1 µl of each of the two solutions to the plate. After developing in a chamber pre-equilibrated with mobile phase for 15 minutes and removal of the plate, dry it in the air, spray with 0.2% ninhydrin ethanol solution. Heat at 105ºC until the colour spots appear clearly. A spot in the chromatogram obtained from the test solution corresponds in colour and position to the spot in the chromatogram obtained from the reference drug solution.

Processing  :

Action  : To replenish qi and invigorate the spleen function, and to promote fluid secretion and moisten the lung.

Indication  : hypofunction of the spleen with lassitude and anorexia; debility and deficiency of qi and yin marked by spontaneous sweating and thirst during convalescence dry cough due to dryness of the lung

Precautions  :

Dosage  : 9 to 30 g.

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