Original form
1. Lauracea perennials. Erect or sometimes climbing, 9-32cm high, with purple juice. Bulb bulbs are purple and about 6mm in diameter. Basal leaves are densely packed into nearly one round or the top few pieces are inserted on the internode elongated stem; Degenerate basal leaves are linear subulate, about 2 mm long; Non-degenerate basal leaves are round or oblate, and wither when flowering; Cauline leaves alternate, peltate, half-moon or semi-circle, 2-3mm long, and there are many head-shaped glandular hairs on the edge or above the leaves, which secrete mucus and form dewdrops. Spiral cymes are born at the top of branches and stems; Bracts cuneate or oblanceolate, with 3-22 flowers; Flowers equal to 5-7, sparsely or densely covered with long glandular hairs on the back, with long glandular hairs on the edge; Petals 5, wedge-shaped, white, reddish or red, longer than sepals and with longitudinal stripes; Stamens 5, about 5 mm long; The pistil is single, the ovary is superior, L-loculed, and the flowers are 3-5. Cucurbita moschata is 2-4mm long and 2-4 locules are dehiscent. The seeds are small and oval, and the veins of the seed coat are thickened into a honeycomb. Flowering and fruiting period is from June to September.
2. The main difference between this variety and the former variety is that the calyx back is hairless and the sparse base has short glandular hairs; Flowers white, styles 2-4, sparse 5; Fruit slices 2-4, sparse 5.
Habitat distribution
Ecological environment: 1. Born at an altitude of 1200-3650m, under pine forests, in grass or beside streams and ditches.
2. Born on hillsides, streams, bushes and sparse forests.
Distribution of resources: 1. Distributed in Sichuan, Guizhou, Yunnan and Tibet.
2. Distributed in Jiangsu, Anhui, Zhejiang, Jiangxi, Fujian, Taiwan Province, Hubei, Hunan, Guangdong, Hainan, Guangxi and other places.
cultivate
1. Soil climate: like fresh and humid air. The soil is made of peat soil and chopped sphagnum moss; But it is not suitable for alkaline soil cultivation.
2. Planting: seed propagation, sowing in cold room or hotbed, sowing without treading soil. After budding, use peat soil for planting, or use cutting propagation and root cutting; Cut it into small pieces, each length is 1 inch, and put it flat in peat soil to keep it warm and moist, that is, take root and sprout.
character
Character identification The whole grass is slender and 5-25cm long. Tubers are spherical, 3-8 mm in diameter; The surface is gray-black, rough, and concave stem marks can be seen at the apex; Light weight, broken flour, yellow to brownish yellow, irregular vascular bundles can be seen.
The stem is round, with a diameter of 0.5-lmm, brown-black surface, longitudinal edges and many hollows. Leaf blade is half-moon-shaped, with many brown silky hairs on the edge; The petiole is slender. The top of the stem often has flowers or small capsules. Slight gas, sweet taste.
Microscopic identification of stem cross section: epidermal cells are square-like, with a few protruding outward; The outer stratum corneum. The cortex is narrow, with about 3 rows of thick-walled cell bands inside, and the wall is lignified. Vascular bundle periwoody type; The vessel wall is lignified, the phloem is compressed, there are single or bundled fibers, the wall thickness is lignified, and the cell cavity contains brown and black substances. The perimedullary parenchyma cells are round or polygonal, and the center is mostly hollow.
Powder characteristics: grayish brown. 1 There are many starch granules, single oval or triangle-like, and a few with punctate umbilicus, with a diameter of 5-33 μ m.. Fiber fragments are common, the side wall is smooth, the end wall is flat and blunt, the cell cavity contains brown and black substances, the diameter is 6-20μm, and the wall is lignified. 3 Ducts with marginal holes are more common, while those with ladder, thread and ring are less, with a diameter of13-37μ m.. Most stomata can be seen in petal epidermis fragments. 5. Pollen grains have a constant number of clusters, with spines on the surface and inconspicuous germination holes, with a diameter of 30-33 μ m.. 6 The head and stalk of glandular hairs are multicellular, brownish yellow, with a diameter of100-115 μ m..
Chemical constituents The whole grass contains naphthoquinones such as plumbagin and droserone.
pharmacological action
For the pharmacological action of jisongsu, please refer to Bai Dan tiao. The extract of Euphorbia zingiberensis contains at least two naphthoquinone derivatives, which has a powerful antispasmodic effect.
2. Glycerol extract and methanol extract from the whole grass of LYSIMACHIA sonchifolia were injected into the lymph sac and thigh muscle of frog, and after 10 hour, local hemorrhagic necrosis was detected.
Identification Physical and Chemical Identification (1) Take 3g of this product, cut it into small pieces, soak it overnight with 200ml of water, then heat and distill it, and collect about 80ml of yellow distillate. Take 2ml distilled liquid in two parts, and add 1% copper sulfate solution1drop to one part, and the red color will disappear after acidification with dilute hydrochloric acid, and then alkalize to Ph 12 with10% sodium hydroxide solution, and the solution will turn red again; Add 2 drops of1%nickel acetate ethanol solution to the other part, and the solution is red. (2) Thin-layer chromatography Take about 70ml of the above distilled liquid, shake and extract it with 20ml of ether, separate the ether solution, and evaporate it to dryness. The residue is decomposed with 0.5ml of ethanol as the test solution, and the ethanol solution of chrysogenin is used as the control solution, and it is spotted on the same silica gel G thin-layer plate with benzene-anhydrous ethanol (8: 2) or cycloethane-chloroform-ethanol (20: 0).
