The bleeding plant - Millettia reticulata

In the tropical rain forest of Xishuangbanna, Yunnan, there grows a plant that can bleed - Millettia reticulata. You may have rarely heard of this. In the plant kingdom, it is these plants with various postures, strangeness and magical colors that deeply attract people and make humans continue to explore the mysteries of the plant kingdom. Millettia is a plant belonging to the genus Millettia in the family Papilionaceae, which has both ornamental and medicinal uses. Yunnan produces 24 species, accounting for more than half of the total number of Millettia spatholobi plants in China. The tropical and subtropical areas in southern, southwestern and northwestern Yunnan are the most resource-rich.

Millettia reticulata is a climbing tree, shrub or tall woody vine. The flower is bisexual and bilaterally symmetrical. The two square petals resembling a butterfly head located on the near axis are the standard petals, the two parallel petals on both sides that are very similar to butterfly wings are the wing petals, and the two petals at the bottom that are fused at the edges and look a bit like the tail of an ally butterfly are the keel petals. The flowers of Millettia reticulata are composed of ventral or terminal racemes or panicles of purple, rose-red or white corollas, hanging in clusters in the air like little butterflies, emitting a rich fragrance of butterfly love, competing for beauty in the air and floating in the wind.

The special thing about Millettia reticulata is that its stems contain a substance that is not found in other leguminous plants. When its stem is cut, its woody body immediately turns light reddish brown, and soon slowly turns into bright red juice that flows out, much like chicken blood. Therefore, people call it chicken blood vine.

The Millettia plant has a wide range of uses. It is used in gardens to provide shade for trellises, having the same effect as wisteria, but its flowers are more colorful. It blooms in late summer and is semi-evergreen in winter, making it more popular. In addition to being used for viewing, vines and roots are used for medicinal purposes, and have the effects of dispersing qi, activating blood circulation, relaxing muscles, and activating joints.

This product is the dried vine of Spatholobus suberectus Dunn, a plant of the Leguminosae family. Harvest in autumn and winter, remove branches and leaves, slice and dry.

[Properties] This product is oval, rectangular or irregular oblique slices, 0.3 to 1 cm thick. The cork is gray-brown, with gray-white spots visible in some places, and the fallen cork appears reddish-brown. Hard texture. The cross section of the xylem is reddish brown or brown, with numerous vascular pores; the phloem has resinous secretions that are reddish brown to dark brown, arranged alternately with the xylem in several concentric elliptical rings or eccentric semicircular rings; the pith is biased to one side. Slight smell, bitter taste.

[Identification] (1) Cross section of this product: several rows of cork cells containing brown-red substances. The cortex is narrow, with scattered groups of stone cells, and the cell cavity is filled with brown-red substances; the thin-walled cells contain prismatic crystals of calcium oxalate. The vascular bundles are heteromorphic, with phloem and xylem arranged in several whorls alternately. The outermost layer of the phloem is a thick-walled cell layer composed of stone cell groups and fiber bundles; the rays are mostly squeezed; the secretory cells are numerous, filled with brown-red substances, and are often 10 to more than 10 arranged tangentially in bands; there are many fiber bundles, which are lignified to slightly lignified, and the surrounding cells contain prismatic crystals of calcium oxalate, forming crystal fibers, and the walls of the crystal-containing cells are lignified and thickened; the stone cell groups are scattered. Some xylem rays contain brown-red substances; most of the vessels are single and scattered, round in shape, with a diameter of about 400μm; the wood fiber bundles also form crystal fibers; a few wood parenchyma cells contain brown-red substances.

(2) The powder of this product is brown-yellow. Brown-red blocks are scattered in different shapes, sizes and shades. The main components are bordered pit vessels with a diameter of 20 to 400 μm, some of which contain yellow-brown substances. The stone cells are scattered singly or in groups of 2 to 3, light yellow, rectangular, sub-circular, sub-triangular or sub-square, 14 to 75 μm in diameter, with obvious stratification. The cells surrounding the fiber bundles contain prismatic calcium oxalate crystals, forming crystal fibers. The prismatic crystals of calcium oxalate are bipyramidal or irregular in shape.

(3) Take 1 g of the powder of this product, add 100 ml of ethanol, heat and reflux for 1 hour, filter, evaporate the filtrate, add 2 ml of methanol to the residue to dissolve it, add 1 g of silica gel and mix well, evaporate the solvent, place it on a silica gel column (100-200 mesh, 2 g, inner diameter 1.0 cm, dry column), and elute with 30 ml of petroleum ether (60-90°C) and 40 ml of methanol-chloroform (1:9) in sequence, collect the methanol-chloroform (1:9) eluate, evaporate to dryness, add 0.5 ml of chloroform to the residue to dissolve it, and use it as the test solution. Take another formononetin reference substance and add methanol to prepare a solution containing 1 mg per 1 ml as the reference substance solution. According to the thin layer chromatography method (Appendix ⅥB), 5-10 μl of the test solution and 5 μl of the reference solution were respectively spotted on the same silica gel G thin layer plate, and chloroform-methanol (20:1) was used as the developing agent. The plate was developed, taken out, dried, and examined under ultraviolet light (254 nm). In the test sample chromatogram, a fluorescent spot of the same color appears at the corresponding position in the reference sample chromatogram.

[Inspection] Moisture content shall not exceed 13.0% (Appendix ⅨH Method 1). The total ash content shall not exceed 4.0% (Appendix ⅨK).

[Extractables] Determined by the hot soaking method under the determination method for alcohol-soluble extracts (Appendix XA), using ethanol as the solvent, the content shall not be less than 8.0%.

【Nature and flavor and meridians】Bitter, sweet, warm. It enters the liver and kidney meridians.

[Functions and indications] Promote blood circulation and replenish blood, regulate menstruation and relieve pain, relax muscles and tendons. Used for irregular menstruation, dysmenorrhea, amenorrhea, rheumatic pain, numbness and paralysis, and blood deficiency and sallow complexion.
