Project description:Zingiber montanum (Z. montanum) and Zingiber zerumbet (Z. zerumbet) are important medicinal and ornamental herbs in the genus Zingiber and family Zingiberaceae. Chloroplast-derived markers are useful for species identification and phylogenetic studies, but further development is warranted for these two Zingiber species. In this study, we report the complete chloroplast genomes of Z. montanum and Z. zerumbet, which had lengths of 164,464 bp and 163,589 bp, respectively. These genomes had typical quadripartite structures with a large single copy (LSC, 87,856-89,161 bp), a small single copy (SSC, 15,803-15,642 bp), and a pair of inverted repeats (IRa and IRb, 29,393-30,449 bp). We identified 111 unique genes in each chloroplast genome, including 79 protein-coding genes, 28 tRNAs and 4 rRNA genes. We analyzed the molecular structures, gene information, amino acid frequencies, codon usage patterns, RNA editing sites, simple sequence repeats (SSRs) and long repeats from the two chloroplast genomes. A comparison of the Z. montanum and Z. zerumbet chloroplast genomes detected 489 single-nucleotide polymorphisms (SNPs) and 172 insertions/deletions (indels). Thirteen highly divergent regions, including ycf1, rps19, rps18-rpl20, accD-psaI, psaC-ndhE, psbA-trnK-UUU, trnfM-CAU-rps14, trnE-UUC-trnT-UGU, ccsA-ndhD, psbC-trnS-UGA, start-psbA, petA-psbJ, and rbcL-accD, were identified and might be useful for future species identification and phylogeny in the genus Zingiber. Positive selection was observed for ATP synthase (atpA and atpB), RNA polymerase (rpoA), small subunit ribosomal protein (rps3) and other protein-coding genes (accD, clpP, ycf1, and ycf2) based on the Ka/Ks ratios. Additionally, chloroplast SNP-based phylogeny analyses found that Zingiber was a monophyletic sister branch to Kaempferia and that chloroplast SNPs could be used to identify Zingiber species. The genome resources in our study provide valuable information for the identification and phylogenetic analysis of the genus Zingiber and family Zingiberaceae.

Project description:Background: Hypercholesterolemia, high cholesterol levels in the blood, can contribute to many forms of disease, most notably cardiovascular disease. Anti-hypercholesterolemic agents generally used for those conditions have several side effects for patients. Zingiber montanum, known locally as "bangle", belongs to the family Zingiberaceae and is a potential plants for alternative anti-hypercholesterolemic agents. This plant, from East Kalimantan, is used in traditional medicine for health problems caused by high cholesterol levels. The aim of this research was to find alternatives to anti-hypercholesterolemic agents, especially from natural sources. Methods: This study was an experimental study using 30 Wistar male white rats. Subjects were randomly divided into 6 groups (n=5): (1) normal control group; (2) high fat diet control group; (3) high fat diet with simvastatin; (4-6) high fat diet with Zingiber montanum extracts 100, 200, and 400 mg/kg. After 4 weeks of treatment, blood was collected from all groups, and plasma concentrations of triglycerides, total cholesterol, high density lipoproteins (HDL), and low density lipoproteins (LDL) were measured. Results: The results showed significant differences in total cholesterol (p=0.000), LDL (p=0.000) and triglycerides (p=0.001) in the high-fat diet group with Z. montanum extract, as compared to the high-fat diet control. Meanwhile, there were no significant differences in HDL levels (p=0.830) between the high-fat diet group and other groups. The results also showed significant differences in total cholesterol and LDLs for rats treated with Z. montanum extract, 100 mg/kg (p=0.000), 200 mg/kg (p=0.000), and 400 mg/kg (p=0.000) compared to the high-fat diet group. The result of Z. montanum 400 mg/kg also showed a significant reduction, not only for total cholesterol and LDLs, but also for triglycerides (p=0.030). Conclusion: It could be concluded that Z. montanum extracts have the potency to be further developed as a new natural source of the anti-hypercholesterolemic agents.
