Genus Cycas, Cycadaceae family, contains about 117 species. Nevertheless, few species have been phytochemically and pharmacologically studied. To date Eighty-eight secondary metabolites, including flavonoids, terpenoids, lignans, aromatic acids and sterols were isolated and identified from nineteen Cycas species. Among the isolated compounds flavonoids are the most prevalent metabolites. The extracts as well as pure compounds isolated from Cycas species were reported to exhibit a wide range of biological activities including; antimicrobial, anti-oxidant, antidiabetic, cytotoxic, anthelmintic, analgesic, anti-arthritic, anti-inflammatory and thrombolytic activities. The present review highlights the reported phytochemical content as well as the pharmacological potential of Cycas species. Interestingly, it indicates that; almost all the previous investigation of the biological activity of pure compounds isolated from this genus was directed towards its flavonoid content. Accordingly, more biological studies are needed to figure out the possible role of other isolated compounds in the observed biological activities and/or the reported traditional uses of different Cycas species. Moreover, further studies are required to investigate other unexplored species.

Codon use bias is an important characteristic in the process of genetic information transmission of species. With the publication of the genome of C. panzhihuaensis, it is of great significance to investigate the codon use bias for understanding the genetic evolution of this species and for molecular breeding. In this study, Perl language and CodonW 1.4.2 software was used to systematically analyze the coding gene sequences of the C. panzhihuaensis genome, obtain the characteristics of codon use, and identify the sources of variation affecting codon use. The results showed that GC3s content, GCall content, and ENC value were 46.75%, 47.67%, and 52.8 respectively. As the first seed plant, the GC3 content of Cycas is similar to that of most gymnosperms and most dicotyledons, but considerably different from that of monocotyledons.RSCU value was greater than 1, among which 21 codons ended in U or A. Enc-plot analysis, PR2-plot neutral plot analysis, and correlation coefficient analysis of Axis1 with GC3s and CAI revealed that the codon bias was mainly affected by natural selection, but also by mutation pressure and other factors. Thirty-one optimal codons of Cycas genes were screened. This research can provide a reference for the phylogeny and genome codon evolution of Cycas.
