Wild Angelica sinensis is almost endangered, studying the biological characteristics of wild A. sinensis seeds is helpful for varietal improvement and its conservation. This paper systematically studied the morphological structure, thousand seed weight, viability, storage and other basic biological characteristics of wild A. sinensis fruits and seeds, and focused on the germination of excised embryos,the development of embryo, the effects of the temperature,light and hormones on seed germination.The study found that:①The embryos are not fully developed when harvested, the initial germination rate was low, the embryos can develop. After 15 days of low temperature storage, the embryos can develop completely and the germination rate is significantly increased. These results show that wild A. sinensis seeds have no dormancy, and the low germination rate is due to the low maturity of wild A. sinensis seeds. ②The sui-table germination temperature of wild A. sinensis is 15-25 ℃,and the optimal temperature is 20 ℃. Light does not affect the germination of A. sinensis seeds.③The applicable concentration of GA_3 can promote seeds germination, IAA and 6-BA has no significant effect on germination.④The optimum storage condition is dry storage at 4 ℃. Wild A. sinensis seeds can be stored for 1.5 years and cultivated seeds can be stored for 1 year.During the introduction and conservation, the best treatment conditions were dry storage at 4 ℃ for 30 d and soaking seeds with 200 mg·L~(-1) GA_3, the germination rate can reach 86.7%.

A crude drug “Dang-Gui”, belonging to the genus Angelica, has been used as a traditional herbal medicine in Asia. Various studies have investigated the chemical components and pharmacological activities of Dang-Gui worldwide. However, domestic research results published in Korean are undervalued in international academia due to language barriers. Therefore, it is necessary to summarize the domestic research findings systematically for greater accessibility. This review focuses on the results published in four Korean pharmaceutical journals between 1970 and 2018, which detail the botanical, phytochemical, and pharmacological properties of three Angelica species (A. gigas, A. sinensis, and A. acutiloba) used as “Dang-Gui” in Korea, China, and Japan.

To establish the water dynamics model for drying process of Angelicae Sinensis Radix, the Weibull distribution model was applied to study the moisture ratio variation curves, and compared the drying rate and drying activation energy with the drying methods of temperature controllable air drying, infrared drying under different temperatures (50, 60, 70 degrees C). The Weibull distribution model could well describe the drying curves, for the moisture ratio vs. drying time profiled of the model showed high correlation (R2 = 0. 994-0. 999). The result proved that the drying process of Angelicae Sinensis Radix belonged to falling-rate drying period. For the drying process, the scale parameter (a) was related to the drying temperature, and decreased as the temperature increases. The shape parameter (β) for the same drying method, drying temperature had little impact on the shape parameter. The moisture diffusion coefficient increase along with temperature increasing from 0.425 x 10(-9) m2 x s(-1) to 2.260 x 10(-9) m2 x s(-1). The activation energy for moisture diffusion was 68.82, 29.60 kJ x mol(-1) by temperature controllable air drying and infrared drying, respectively. Therefore, the Weibull distribution model can be used to predict the moisture removal of Angelicae Sinensis Radix in the drying process, which is great significance for the drying process of prediction, control and process optimization. The results provide the technical basis for the use of modern drying technology for industrial drying of Angelicae Sinensis Radix.

The demand for Angelicae Sinensis Radix, the dry root of Angelica sinensis, has been increasing year by year. However, the continuous cropping obstacles, frequent occurrence of pests and diseases, overuse of chemical pesticides, excessive pesticide residues and other problems in Angelicae Sinensis Radix production have attracted much attention. In this paper, we summarized the common diseases and pests attacking Angelica sinensis as well as the detection methods and characteristics of pesticide residues in Angelicae Sinensis Radix from 2002 to 2021. Additionally, we compared the limit standards of pesticide residues in Angelicae Sinensis Radix in and out of China and put forward suggestions for the high-quality and green development of Angelicae Sinensis Radix industry conside-ring the existing problems. The pesticide residues in Angelicae Sinensis Radix have been changing from organochlorines to organophosphorus pesticides. In recent years, some organophosphorus pesticides such as phorate, phoxim, isofenphos-methyl, phorate-sulfoxide, fenamiphos, isocarbophos, omethoate, and triazophos in Angelicae Sinensis Radix have seriously exceeded the standards. The detection methods of pesticide residues has evolved from chromatography to high performance chromatography-mass spectrometry, gas chromatography-mass spectrometry(GC-MS), and liquid chromatography-mass spectrometry(LC-MS), and some new detection techniques such as immunoassay have also been applied. Pesticide residues have become a primary factor that restricting the development of Angelicae Sinensis Radix industry. Therefore, moderate application of pesticides, establishment of ecological planting system, and strict limit standards of pesticide residues are necessary to solve the pesticide residue problem.
