GC-MS analysis of the composition of petroleum ether extract from stem of Panax japonicus was written by Lai, Pu-hui;Tian, Guang-hui;Gao, Yan-ni;Cai, Chun-yu;Liu, Cun-fang. And the article was included in Anhui Nongye Kexue in 2008.SDS of cas: 28020-37-3 This article mentions the following:
The study was to provide the basis for the comprehensive development and utilization of the stem of Panax japonicus in Qinba Mountains. With petroleum as solvent, the petroleum extraction from the powder of wild P. japonicus stem in Qinba Mountains extracted by ultrasonic, and its composition was separated and identified by GC-MS anal. 49 Compounds were separated and identified in the petroleum extraction of the stem of P.japonicus, and the main compounds were terpenes, fatty acids, enols, olefins and phenolic compounds, which shared 95.15% of the total liposol. constituents. The compound with the highest relatively content was spathulenol (22.07%), the second was palmitic acid with the content of 11.18%, and the third was selinene with the content of 9.20%. Their construction all contained unsaturated double bonds, which indicated that the petroleum extraction from the wild P. japonicus stem could had some physiol. activity. The petroleum extraction from the P. japonicus stem had good value on application and exploitation. In the experiment, the researchers used many compounds, for example, 3-Amino-2,6-dimethoxypyridine (cas: 28020-37-3SDS of cas: 28020-37-3).
3-Amino-2,6-dimethoxypyridine (cas: 28020-37-3) belongs to pyridine derivatives. The ring atoms in the pyridine molecule are sp2-hybridized. The nitrogen is involved in the π-bonding aromatic system using its unhybridized p orbital. The lone pair is in an sp2 orbital, projecting outward from the ring in the same plane as the σ bonds. One of the examples of pyridines is the well-known alkaloid lithoprimidine, which is an A3 adenosine receptor antagonist and N,N-dimethylaminopyridine (DMAP) analog, commonly used in organic synthesis.SDS of cas: 28020-37-3
