Problems solved by technology

"Chinese Pharmacopoeia" 2010 edition one part only stipulates that the content of ferulic acid should not be less than 0.1% in the quality evaluation index of Chuanxiong medicinal materials, and does not make regulations on other medicinal ingredients. In some reported cultivation techniques of Chuanxiong In the literature, only the contents of ferulic acid and alkaloids were investigated, and there was no study on the effects of sowing period or other cultivation techniques on the effects of chuanxionglide I, chuanxionglide H and chuanxionglide A in Chuanxiong medicinal materials. , galusylactone and angelica lactone A and other substances content

Embodiment Construction

[0013] The present invention will be further described in detail below in combination with specific embodiments.

[0014] A method for increasing the content of lactones in Rhizoma Chuanxiong medicinal materials by using the sowing period. First, select a plot with a higher terrain as the land for production of Rhizoma Chuanxiong. The irrigation and drainage conditions must be good. Level the land, and then ditch it as a box with a width of about 1-2 meters. Secondly, choose high-quality Lingzi from the Zhengshan line, discard the inferior Lingzi seeds that have been damaged by diseases and insect pests or have germinated, and soak the seeds with non-toxic or low-toxic pesticides (such as carbendazim, thiophanate-methyl) before sowing, and drain the seeds. For planting, sow from August 1 to August 5 every year, and sow 8,000 to 10,000 plants per mu. Third, fertilization was carried out 4 times after sowing, the first fertilization was carried out 25 days after sowing, and the...

Abstract

The invention discloses a method for improving the lactone substance content in ligusticum wallichii medicinal materials by utilizing the seeding time, and belongs to the field of cultivation technical research of medicinal plants. According to the method, it is determined that the seeding time ranges from August 1st to August 5th (before the beginning of autumn) every year, and is 10-20 days earlier than the seeding time (from August 10th to August 20th, namely from the beginning of autumn to the limit of heat) in traditional production, and therefore the content of five lactone substances in the ligusticum wallichii medicinal materials can be improved, wherein the five lactone substances are senkyunolide I, senkyunolide H, senkyunolide A, ligustilide and levistilide A.

Description

technical field [0001] The invention belongs to the field of medicinal plant cultivation research, and relates to a method for increasing lactone substances in Chuanxiong medicinal materials. Background technique [0002] Chuanxiong (Ligusticum chuanxiomg Hort.) is a perennial herb of the genus Ligusticum in the family Umbelliferae. Compounds such as alkalis and organic acids. The lactones of Chuanxiong have the functions of relaxing blood vessels and inhibiting thrombosis, and are often used in the treatment of cardiovascular and cerebrovascular diseases, such as myocardial infarction, coronary heart disease, acute cerebral ischemia, chronic cerebral ischemia and other diseases. Therefore, it is very important for clinical application to increase the content of lactones in Chuanxiong medicinal materials. [0003] Chuanxiong is mainly planted in Dujiangyan City and Pengzhou County in Sichuan Province, and also in Shifang and Pengshan Counties. These planting areas are gene...
