Other Novel Skeletal Plant Natural Products

In addition to the above 11 new type skeleton compounds, there are also 113 new skeletons of other classes (1999–2021) and they contain 23 subclasses (1253‒1294 Fig. 13.1, 1295‒1340 Fig. 13.2, 1341‒1365 Fig. 13.3; Table A12). In view of the relatively small number of new skeleton compounds contained in each subclass, the 113 unique compounds were classified as other groups. The detailed classification of the subclasses will be described in this chapter.
