The whole cp genome of was 159,502 bp in length, containing a pair of inverted repeat (26,961 bp for each), a large single copy (87,199 bp) and a small single copy (18,381 bp) regions. The cp genome encoded 138 genes, including 89 protein-coding genes, 40 tRNA genes, 8 rRNA genes and 1 pseudogene. The nucleotide composition was asymmetric (30.7% A, 19.3% C, 18.6% G and 31.4% T) with an overall GC content of 37.9%. The maximum likelihood phylogenetic analysis based on 21 complete cp genome sequences showed that closely related to Azadirachta indica.
该植物的完整叶绿体基因组长度为159,502 bp，包含一对反向重复序列（每个26,961 bp）、一个大单拷贝区（87,199 bp）和一个小单拷贝区（18,381 bp）。叶绿体基因组编码138个基因，包括89个蛋白质编码基因、40个tRNA基因、8个rRNA基因和1个假基因。核苷酸组成不对称（A占30.7%，C占19.3%，G占18.6%，T占31.4%），总体GC含量为37.9%。基于21个完整叶绿体基因组序列的最大似然系统发育分析表明，该植物与印楝关系密切。
