The article discusses chemical composition of Arabidopsis thaliana. It is stated that study has become the model system for studying various aspects of plant biology and biochemistry. It is stated in 2009, wild herbs of A. thaliana were collected from Jiande, Zhejiang, China, and dried and powdered material was extracted with 95% EtOH at room temperature.

Published in Khimiya Prirodnykh Soedinenii, No. 1, January-February, 2020, pp. 127-128 I Zanthoxylum bungeanum i Maxim., which belongs to Rutaceae, is a woody plant with abundant resources and has long been cultivated in tropical and temperate regions of North America, South America, Africa, Asia, and Australia [[1]]. Each subfraction was subsequently purified using Cosmosil 75 C18-OPN with a gradient of H SB 2 sb O-MeOH (1:0, 9:1, 4:1, 100 mL for each step) and Toyopearl HW-40F eluted with H SB 2 sb O to yield B 1 b (17.7 mg). Fraction B was subjected to Toyopearl HW-40F column chromatography with a gradient of H SB 2 sb O-MeOH (1:0, 9:1, 4:1, 7:3, 300 mL for each step) to yield three fractions Frs.
