Embodiment 1

[0055] 1) Identification of Huaijiao Formula Granules:

[0056] a, the preparation of contrast medicinal material solution:

[0057] Take 0.5g of Sophora japonicus reference medicinal material, add 50ml of water, boil for 30 minutes, filter, evaporate the filtrate to dryness, add 2ml of methanol to the residue to make a reference medicinal material solution;

[0058] b. Preparation of the test solution:

[0059] Take 9 batches of Sophora japonica formula granules, grind them finely, take 1.0g each, add 20ml of methanol, ultrasonicate for 30 minutes (power 300W, frequency 25kHz), filter, evaporate the filtrate to dryness, add 2ml of methanol to the residue to dissolve, as The test solution;

[0060] c, TLC determination:

[0061] Take the above-mentioned control medicinal material solution and the test solution, respectively spot on the same silica gel GF254 thin-layer plate, use ethyl acetate-formic acid-water (8:1:0.1) as the developer, pre-equilibrate for 30 minutes, deve...

Abstract

The invention discloses a detection method of a fructus-sophorae formula granule. The invention also discloses a detection method of sophoricoside in a fructus-sophorae preparation. According to a quality detection method of the fructus-sophorae formula granule, which is provided by the invention, the thin-layer chromatography of a fructus sophorae containing formula granule and a content determination method of the fructus-sophorae formula granule are established; the detection method is simple; the invention also provides the detection method of the sophoricoside in the fructus-sophorae preparation; and the method is high in detection accuracy and has a favorable application prospect.

Description

technical field [0001] The invention specifically relates to a quality detection method of Huaijiao formula granules. Background technique [0002] Sophora japonica L. is the dry ripe fruit of Sophora japonica L., a leguminous plant. [0003] Sophora japonica (National Sophora japonica) plant form: deciduous tree, 15-25 meters high, DBH up to 1 meter. The crown is spherical or broadly ovate, the bark is rough, with irregular longitudinal fissures, dark gray, the inner bark is bright yellow, and smells. Odd-pinnate compound leaves alternate, base of petiole enlarged, rachis hairy, leaflets 7-17, petioles hairy; stipules sickle-shaped, leaflets ovate-lanceolate or ovate-oblong, apex with fine protrusions Pointed, entire, base round or wide wedge-shaped, dark green above, smooth, below white-green, with white hairs, prominent main veins, not obvious side veins. Terminal large panicle with hairy pedicels and small pedicels; calyx bell-shaped; corolla butterfly-shaped, yellow-...
