Source

The source of medicinal materials: the mature seeds of Indian Trunpetflower Seed

Latin plant animal mineral name: Oraxylum indicum (L.) Kurz [Bignon-ia indica L.]

Harvesting and storage: Harvest mature fruits in autumn and winter, expose them to the sun until the fruits crack, take out the seeds and dry them in the sun.

Identification

 1) This herb is yellow or yellow-green powder. Species wing cells are fibrous, with wavy thickened walls, 20-40 μm in diameter; endosperm cells are polygonal, with rosary-like thickened walls.

2) Take 2g of this product powder, add 30ml of ethanol, heat under reflux for 15 minutes, filter, add 0.5g of boric acid to the filtrate to dissolve, filter, and use the filtrate as the test solution. Another reference substance of baicalin was taken, and ethanol was added to make a solution containing 1 mg per 1 ml, which was used as the reference substance solution.

According to the thin-layer chromatography (Appendix VI B) test, draw 10 μl of each of the above two solutions, and place them on the same silica gel-thin-layer plate, using n-butanol-acetic acid-water (6:1.5:2.5) as the developing solvent, Unfold, remove, and dry. In the chromatogram of the test substance, there are spots of the same color at the position corresponding to the chromatogram of the reference substance.

Original form Wood butterfly Wood tree, 7-12m high. The bark is thick, with lenticels. Branchlets lenticels numerous and protruding, leaf scars obvious and large. Opposite leaves; large odd-numbered two- to four-pinnate compound leaves, inserted near the top of the stem, 60-160cm long, 20-80cm wide; many leaflets, petioles 5-10mm long, small leaves triangular-ovate , 6-14cm long, 4-9cm wide, apex short acuminate, base rounded or broadly cuneiform and oblique, entire, green above, pale green below, glabrous on both sides, blue when dry. Raceme cymes terminal, 40-150cm long, pedicel about 7cm long; calyx campanulate, 2.2-4.5cm long, 2-3cm wide, purple, truncated before Shang, persistent; corolla orange-red, fleshy, long 3-9cm, bell-shaped, 5-8.5cm in diameter, 5-lobed at the apex, lobes of varying sizes; 5 stamens, inserted in the middle of the corolla tube, protruding from the outside of the corolla; the base of the filaments is woolly, one of which is shorter ; Huapan Lei, fleshy; style 5-7cm long, 2 stigmas dehiscent. Capsules are woody, flat, broadly linear, pendulous, 40-120cm long, 5-8.5cm wide, apex short-pointed, base cuneiform, edges slightly incurved, with a slightly protruding dorsal slit in the middle, brownish yellow when mature, along the ventral slit Lines dehiscent, fruit petals with middle ribs. Seeds are numerous, seeds with wings 6-7.5cm long and 3.5-4cm wide, except for the base, all surrounded by thin white translucent wings. The flowering period is July-October, and the fruiting period is October-December.

Character identification

 Seeds are nearly oval, flaky, 2-3cm long and 1.5-2cm wide. The surface is light yellow-white, with silk-like luster. The seed coat expands outward into broad wings on three sides, about 2.5cm wide, membranous translucent, with radial texture, and the edges are often broken. The body is light, the seed coat is peeled off, and there are membrane-like endosperm and tightly packed cotyledons. Cotyledons 2, flat butterfly-shaped, yellow-green or light yellow, about 1.5cm long diameter, short diameter about 1cm; radicle obvious. Gas micro, slightly bitter taste.

It is better if it is large, white in color, shiny, and soft as silk.

Microscopic identification

 Seed cross section: more than 10 columns of seed coat cells. Endosperm cells are more than 4-10 columns. The upper epidermal cells of the cotyledons are nearly square, and the lower epidermal cells are slightly smaller; the palisade tissue cells contain oil droplets and chloroplasts; the spongy tissue cells are closely arranged, contain oil droplets and starch granules, and are distributed in vascular bundles.

Powder characteristics:

stem yellow or yellow-green. Species wing cells are long fibrous, with wavy thickened walls, 20-40 μm in diameter; endosperm cells are polygonal with rosary-like thickened walls.

Thin-layer chromatography: take 2g of this product powder, add 30ml of ethanol, reflux for extraction for 15min, filter, add 0.5g of boric acid to the filtrate to dissolve, filter, and the filtrate is used as the test solution.

Another reference substance of baicalin was taken, and ethanol was added to make a deep solution containing 1mg per 1ml, as the reference substance solution. Pipette 10 μl of each of the above two solutions, and spot them on the same silica gel G thin-layer plate respectively, use n-butanol-acetic acid-water (6:1.5:2.5) as the developing agent, unfold, take out, and dry.

In the chromatogram of the test substance, there are spots of the same color at the position corresponding to the chromatogram of the reference substance.

Chemical composition

Seeds contain 20% fatty oil, of which oleic acid accounts for 80.4% [1]. It also contains benzoic acid, chrysin, oroxin A, B [2], baicalein, tetuin [3], 5-hydroxy-6 , 5-hydroxy-6,7-dimethoxyflavone, oroxylin A, 5,6-dihydroxy-7-methoxyflavone ), hispidulin, apigenin, scutel-larein, chrysin-7-O-beta-D-glucopyra-noside, chrysin-7-O-beta- gentiobioside (chrysin-7-O-β-gen-tiobioside), baicalin (baicalin), scutellarin (scutellarin) [4], oroxindin, namely wogonin-7-O- β-D-glucuronide (wogonin-7-O-β-D-glucuronde) [5].

The leaves contain baicalin, alpine baicalein, and alpine baicalin [6].

Pharmacological effects Seeds and stem bark contain baicalin, which has anti-inflammatory, anti-allergic, diuretic, choleretic, and cholesterol-lowering effects. The seeds and stem bark contain chrysin, which has cytotoxic activity on human nasopharyngeal carcinoma (KB) cells, and its half effective dose is 13mg/ml.
