| 1 | Alkaloid profiling of the traditional Chinese medicine Rhizoma corydalis using high performance liquid chromatography-tandem quadrupole time-of-flight mass spectrometry显示文摘Since alkaloids are the major active constituents of Rhizoma corydalis(RC),a convenient and accurate analytical method is needed for their identification and characterization.Here we report a method to profile the alkaloids in RC based on liquid chromatography-tandem quadrupole time-of-flight mass spectrometry(LC–Q-TOF-MS/MS).A total of 16 alkaloids belonging to four different classes were identified by comparison with authentic standards.The fragmentation pathway of each class of alkaloid was clarified and their differences were elucidated.Furthermore,based on an analysis of fragmentation pathways and alkaloid profiling,a rapid and accurate method for the identification of unknown alkaloids in RC is proposed.The method could also be useful for the quality control of RC. | Mingqian Sun Jianxun Liu Chengren Lin Lan Miao Li Lin | 2014 | Acta Pharmaceutica Sinica B2014，4，3： | 14 |
| 2 | Simple and Efficient Cultivation Technology for the Peanut under the Standardization Mode of Single-seed Sowing显示文摘Single-seed sowing is a new,simple and efficient cultivation mode for peanut that realized from cultivation of healthy individual and construction of high-yielding population. The cultivation mode has the obvious advantages in uniform seedling,strong sprouting,seed saving and cost saving,thus it is considered as one of the effective ways for high-yield and high-efficient peanut cultivation in China in the future.Through integrating with other high-efficiency and simple cultivation measures,the single-seed sowing technology system has made conforming to China's national standardization cultivations of peanut and the technology was already applied in the main producing areas of peanut and gained the significant efficiency and abroad application prospects. Based on many years of researches in single-seed sowing technology,high-efficiency fertilization and scientific chemical control in the research team,by combining with the latest research results in plant protection and machinery,this paper described the key points and matters needing attentions from variety selection,planting mode,rational fertilization,planting specifications and field management. | Hao FENG Zhengfeng WU Jiancai LIN Tianyi YU Yongmei ZHENG Xuewu SUN Pu SHEN Chengren SHI Caibin WANG | 2016 | Asian Agricultural Research2016，8，6： | 1 |
| 3 | Studies of cocoa tea, a wild tea tree containing theobromine显示文摘Camellia ptilophylla Chang is a wild tea tree containing theobromine and is caffeine-free.Lots of researches have been conducted for its domestication since it was discovered to contain theobromine in its shoots.First,its pharmacological and physiological effects have been studied,demonstrating that it can be used as a new resource of tea as daily and healthy beverage.Cocoa tea differs from traditional tea in that it does not excite the nervous system.Second,various ways of propagation have been investigated,and sexless cutting has been the method adopted currently.Third,through selection and breeding,plantation of cocoa tea can be set up to cultivate new varieties,and cocoa tea of different flavors such as green cocoa tea,oolong cocoa tea,and black cocoa tea can be processed.Thus,cocoa tea will become a choice in the tea market. | Xiaohong SONG Xianggang SHI Yunqin LI Li PENG Chengren LI Xiaorong YANG Chuangxing YE Jiaxian LI Yumei HE Hualin HUANG Aiqing MIAO Chaoyi ZHAO Jiayao WU Caijin LIN | 2009 | Frontiers in Biology2009，4，4： | 0 |
