Chaenomeles speciosa

Background

Chenmugua ³Âľ¹Ï Xuanmugua Ðûľ¹Ï Chinese Name (pinyin): Mugua

Chinese Name  :

Common Name  :Chaenomeles Fruit

Specific Name  : Fructus chaenomelis

Scientific Name:
Collection  : The drug is collected in summer and autumn when the fruit turns greenish yellow, boiled in water until the exocarp becomes greyish white in color, halved longitudinally and dried in the sun.

Description  : Mostly in longitudinally oblong halves, 4 - 9cm long, 2 - 5cm wide, 1 - 2.5cm thick. Externally purplish red or reddish brown with irregular, deep wrinkles, edge of cut surface rolled inwards, pulp reddish brown, central part dented, brownish yellow. Seed long triangular, mostly falling off. Texture hard, odor slightly aromatic and taste sour.

Identification  : To 1g of the powder add 10ml of 70% ethanol, het under reflux for 1 hour and filter. Carry out the following test on the filtrate.1.Evaporate 1ml of filtrate to dryness and dissolve the residue in 1ml of acetic anhydride in the test tube. Add along the tube wall 1 - 2 drops of sulfuric acid, a purplish red color is produced at the junction of the two layers, a brownish yellow color is shown at the upper phase.2.Spot the filtrate on a piece of a filter paper, allow to dry and spray with aluminum chloride TS. Allow it to dry and examine under ultra violet light (365nm), a blu fluorescence is shown.Acidity: To 5g of the powder add 50ml of water, shake well, allow to stand for 1 hour and filter. PH of the filtrate, 3 - 4

Processing  : Wash clean, soften or steam thoroughly, cut into thin slices and dry it in the sun.

Action  : To lessen contracture, regulate stomach function, and dispel damp.

Indication  : arthritis with ankylosis, aching with feeling of heaviness in the loins and knees; systremma due to vomiting and diarrhea; edema and weakness of the legs

Precautions  :

Dosage  : 6 to 9 g.

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