Historical Use of Fritillaria ussuriensis
Fritillaria ussuriensis in Traditional Chinese Medicine
Chinese Name (pinyin): Pingbeimu
Chinese Name :
Common Name :Ussuri Fritillary Bulb
Specific Name : Bulbus Fritillariae Ussuriensis
Collection : The drug is collected in spring, removed from outer bark, fibrous root and soil, dried in the sun or at low temperature.
Description : Oblate, 0.5-1 high, 0.6-2cm in diameter, externally milk white or plate yellowish white or pale yellowish white, outer scale leaves 2, uniform in size or the large scale leaf embracing the small one, apex slightly flat or concave, frequently slightly split, scales in the center small. Texture: hard and fragile, fracture starchy. Odor slightly, Taste: bitter.
Identification : 1.Powder: starch granules simple, rounded triangular, ovoid, rounded-conchoidal, triangularovoid, long-cocooned, 6-58 (-74) µm in diameter up to 67µm long, hilum cleft like, pointed or V shaped in the smaller end, striation dense and distinct. Semi-compound few, hilum 2, simple granules with multihilum visible occasionally, hilum 2-4. Stomata subrounded or depressed rounded. 40-48 (50)µm in diameter with 4-6 subsidiary cells.2.Macerate 2g of the powder in 20ml of water on a water bath at 60ºC for 10 minutes, filter immediately, shake vigorously, 2ml of the filtrate in a stoppered test tube for 1 minute, foam is produced, standing persisting over 10 minutes.3.Heat under reflux 5g of the powder in 35ml of 0.5% solution of hydrochloric acid in ethanol on a water bath for 10 minutes, filter while hot. 15ml of the filtrate add 5% ammonia solution to neutralize, evaporate to dryness on a water bath. Dissolve the residue in 3ml of 5% sulfuric acid solution and filterr. Transfer the filtrate to three test tubes respectively. For the first test tube add 2 drops of silicotungstic acid TS, a greyish-white precipitate is produced, to the second tube add 2 drops of potassium iodobismuthate TS, a reddish-brown precipitate is produced, to the last tube add mercuric potassium iodide TS, a white precipitate is produced.4.5g of the powder add 2ml of the concentrated ammonia TS, 20ml of chloroform, stir well, allow to stand over night and filter. Evaporate the filtrate to dryness, dissolve the residue in 0.4ml of chloroform as the test solution. Prepare a solution of Bulbus Fritillariae Ussuriensis reference drug in the same manner as the reference drug solution and dissolve peimine CRS and peiminine CRS in the chloroform to produced a solution containing 0.5mg of each per ml as the reference solution. Carry out the method for thin layer chromatography (Appendix Vl B) using silica gel G prepared with 0.5% sodium hydroxide solution as coating substance and the lower layer of chloroform-ethyl acetate-methanol-water (30:40:20:10) standing below 10ºC as the mobile phase. Apply separately to the plate 4-6µl of each of the three solutions. After developing and removal of the plate, dry it in the air. Spray with potassium iodobismuthate TS and ethanolic sodium nitrite TS successively. The spots in the chromatogram obtained with the test solution correspond in position and color to the spots in the chromatogram obtained with the reference drug solution. The two brown spots in the chromatogram obtained with the test solution correspond in the position and color to the spots in the chromatogram obtained with the reference solution.
