[Development research of the genetics textbook in Chinese universities].

Textbook construction is an important part of course construction. The development of the Chinese genetics teaching has been full of ups and downs, demonstrating its specificity compared with other subjects of life science. Through the investigation upon the developmental course of genetics textbooks in China from before liberation to the 21st century, we hope that we can provide valuable reference for composing new textbooks that fit the characteristic of undergraduates teaching, and keep close to the genetics front, bringing valuable reference to the cultivation of application and study talents with basic genetics knowledge and innovation ability.

Tetraenol, a novel sesquiterpenoid from the relict plant Tetraena mongolica in China.

A novel furansesquiterpenoid, tetraenol, was isolated from a relict shrub plant, Tetraena mongolica, collected from the northern desert of the Ningxia Hui Autonomous Region. The structure of the new compound was elucidated on the basis of spectroscopic analysis.
