Overview
Ardisia Herb is the dried whole plant of Ardisia japonzca (Thunb.) Blume (Fam. Myrsinaceae). The drug is collected in summer and autumn when the stems and leaves are luxuriant, removed from sand and soil, and dried.
Description
Rhizome cylindrical, with sparse adventitious roots. Stem slightly flattened cylindrical, slightly twisted, 10-30 cm long, 0.2-0.5 cm in diameter; surface reddish-brown, with fine longitudinal wrinkles, leaf scars and nodes; texture hard, easily broken. Leaves alternate, clustered at the stem apex; leaf blades slightly curled or broken, elliptical when flattened, 3-7 cm long, 1.5-3 cm wide; grayish-green, brownish-brown or light reddish-brown; apex acute, base wedge-shaped, margin finely serrate; nearly leathery. Occasionally red spherical drupe at the top of the stem. Odour, slight; taste, slightly astringent.
Identification
Stem transverse section: epidermal cells with thick walls, glandular hairs present; cork layer visible in old stems. Cortex wide, with several rows of thick-walled cells on the outer side; some containing calcium oxalate prisms; secretory cavities present. Endodermis distinct. Phloem very narrow, with a few fibers on the outer side. Cambium ring indistinct. Xylem cells all lignified, vessels mostly arranged in a single row. Pith relatively large, with secretory cavities. Thin-walled cells containing calcium oxalate prisms and starch grains, some containing brown substances.
Leaf surface of the drug: epidermal cells with wavy periclinal walls; stomata anisocytic, occasionally anomocytic. Glandular scales with 8-10 cells at the head and a single cell at the stalk.
Powder of the drug brown. Spiral vessels more common, diameter 7.5-25 μm. Secretory cavities mostly broken, some containing yellowish-brown secretions, secretory cells containing brown substances visible. Fiber walls thick. Calcium oxalate prisms diameter 7.5-26 μm. Glandular hairs composed of a single-cell stalk and a two-cell head. Stomata anisocytic. Brownish lumps visible. Starch grains single, oval or round, diameter 3.8-23 μm, hilum punctate or fissured; compound grains composed of 2-3 sub-grains.
To 0.2 g of the powder add 20 ml of methanol, treat with ultrasound for 30 minutes, cool, filter, concentrate the filtrate to 1 ml as the test solution. Take another 1 ml of methanol to dissolve 0.5 mg of bergenin CRS 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 dichloromethane-acetic ether-methanol (5:4:2) as the mobile phase. Apply separately to the plate 3 μl of each of the above two solutions. After developing and removal of the plate, dry in air. Spray with a mixed solution of 1% ferric chloride and 1% potassium ferricyanide (1:1). The fluorescent 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.
Examination
Water
Not more than 13.0 per cent <0832,method 2>.
Total ash
Not more than 8.0 per cent <2302>.
Assay
Carry out the assay by high-performance liquid chromatography <0512>.
Chromatographic conditions and system suitability test
Use octadecylsilane-bonded silica gel as the filler; use methanol-water (20:80) as the mobile phase; detect at a wavelength of 275nm. The theoretical plate number calculated based on the peak of baicalin should not be less than 1500.
Preparation of reference solution
Take an appropriate amount of baicalin reference substance, accurately weigh, add methanol to make a solution containing 50μg per 1ml.
Preparation of test solution
Take about 0.2g of the powder of this product, accurately weigh, place it in a stoppered conical flask, accurately add 20ml of methanol, weigh, subject to ultrasonic treatment (power 200W, frequency 40kHz) for 40 minutes, cool, weigh again, make up for the weight loss with methanol, shake well, filter, and take the filtrate.
Assay method
Accurately take 5μl of the reference solution and the test solution, inject into the liquid chromatograph, and determine.
Calculated on the dried product, the content of baicalin (C14H16O9) should not be less than 0.50%.
Prepared slices
Ardisia Herb
Processing
Eliminate Foreign matter, wash, cut into sections, and dry in the sun.
Description
This product is in irregular segments. The rhizome is terete and curved, sparsely fibrous. The stem is slightly compressed cylindrical, with a reddish brown surface, with fine longitudinal lines, some with branches and alternate leaf scars. The cut surface has a light brown pith in the centre. Leaves more broken, grey-green to brown-green, apical more pointed, base cuneate, margin serrulate, subleathery. Slightly astringent taste.
Examination
Water
Same as the crude drug. Not more than 11.0 per cent.
Total ash
Same as the crude drug.
Identification
(except stem cross-section, leaf surface view) Same as the crude drug.
Assay
Same as the crude drug.
Property
Neutral.
Flavor

Meridian tropism
Lung and liver meridians.
Actions
To resolve phlegm and stop coughing, clear and eliminate damp-heat, activate blood circulation and resolve stasis.
Indications
Used for cough with phlegm, asthma with fullness, damp-heat jaundice, blood stasis due to menstrual disorders, rheumatic arthralgia, and traumatic injury.
Dosage
15-30 g.
Administration
None.
Storage
