The daisy flowers are dried buds of the plant Lime of the family Rubiaceae, also known as lime blossom, huiqing orange, tortoiseshell, distributed in various regions of southern China. Tortoiseshell flowers contain both cardiac glycosides and non-cardiac glycosides, which have been recorded in many national pharmacopoeias. Chinese medicine is said to have the effect of strengthening the heart, sedation, soothing the liver, digestion, sputum, etc., and is used to treat acute diseases such as chronic cardiac insufficiency, congestive heart failure and epilepsy.
1. Introduction of varieties
The generation flower (Latin name: Citrus × aurantium) belongs to the family Rubiaceae, citrus. Small tree, densely leafy, with many thorns, long branches with spines up to 8 cm long. With its green leaves and golden fruits hanging, it is a rare product among domestic flowers. The fruit of the generation flower is dark green at the beginning, and when it matures, it appears orange-yellow, and does not fall off until the spring and summer of the following year and becomes blue-green, so it is called "back to green orange". If the maintenance is successful, the fruit can be stored until the third year, so it is also called "generation". Harvested in batches from May to June when the flowers are not in bloom, they are dried in time. It is preferable to be complete, yellow and white, and have a strong aroma.
Generational flowers are distributed all over the south slope of the Qinling Mountains, usually planted, sometimes escaping to semi-wild. It is native to Zhejiang, China, and is now cultivated in all provinces of southeastern China. There are many potted plants in North China and the middle and lower reaches of the Yangtze River Basin. Generational flowers prefer warm and humid environments, like light, fat, and slightly hardy.
2, the main value
Generation flowers are dried buds of generation flowers of russets, also known as tortoiseshell flowers, lime flowers, and green orange blossoms. "Kaibao Materia Medica" is the earliest ancient book to record this medicine, because the fruit of the generation is initially dark green, after ripening it appears orange-yellow, to the spring and summer of the second year, it becomes turquoise, and in the third year there will be the same cycle, so it is called "generation". The main production is Jiangsu and Zhejiang, harvested in May-June, low temperature drying.
The generation flower is rich in flavonoids, and the flavonoid components hesperidin and naringin have anti-inflammatory effects. Many flavonoids have antitumor activity, while the total flavonoids in generational flowers exhibit selective cytotoxic effects, resistance to proliferation and induce apoptosis.
The components such as heliperidin contained in the generation flower can inhibit the proliferation of human breast cancer cells and human colon cancer cells, but they do not induce apoptosis of tumor cells, and after stopping the drug, the cells regain activity. The D-limonene in generation flowers mainly inhibits tumor growth and metastasis elimination by inducing apoptosis and scavenging free radicals, thereby inhibiting tumor angiogenesis and pro-apoptotic effect.
The whole herb contains a variety of ingredients of cardiac glycosides and non-cardiac glycosides, which are found in medicinal foods in many countries. Chinese medicine calls it Fushou herb. It has the function of strengthening the heart, diuresis, sedation and slowing the heart rate, can reduce the excitability of the nervous system and hyperreflexia of the spinal cord, and is used for acute diseases and chronic cardiac insufficiency. Indications for the treatment of congestive heart failure, cardiac edema and atrial fibrillation, combined with silver bromide can enhance the therapeutic effect of epilepsy.
3. Propagation and promotion technology
Generational flowers are generally based on cuttings and grafting reproduction, but the varieties and strains of lime are very complex, and the affinity performance after grafting is very different. It is also susceptible to seasonal influences and cannot carry out large-scale seedlings. If the open source creator's plant non-test tube efficient rapid propagation technology (TERNPC) is used to expand the generation of flowers, it can carry out pure seedlings, no variation, low cost, short cycle, large-scale and industrial production of generation flowers, and can quickly supply all sectors of society.
This technology can maintain the excellent characteristics of the original plant, and only one leaf and one bud of the branch can be used as a material on the seedbed to cultivate a new generation of flowers. At present, 989 species of plants have successfully propagated new plants with this technique, and the plants reproduced by this technique have taken root faster and have very developed root systems compared with cuttings. The selection of plant non-test tube efficient and fast propagation technology can meet the market's demand for generational flower seedlings in a short period of time, and at the same time, it can greatly save germplasm resources, avoid the waste of germplasm materials, and save manpower and material resources.
