“…Despite their vast diversity and utility, species of family Zingiberaceae are seldom subjected to genetic and molecular biology research (Gao et al ; Xia et al ). Little information is available on the performance of known barcode loci on Indian members of this family.…”

We evaluated nine plastid (matK, rbcL, rpoC1, rpoB, rpl36-rps8, ndhJ, trnL-F, trnH-psbA, accD) and two nuclear (ITS and ITS2) barcode loci in family Zingiberaceae by analyzing 60 accessions of 20 species belonging to seven genera from India. Bidirectional sequences were recovered for every plastid locus by direct sequencing of polymerase chain reaction (PCR) amplicons in all the accessions tested. However, only 35 (58%) and 40 accessions (66%) yielded ITS and ITS2 sequences, respectively, by direct sequencing. In different bioinformatics analyses, matK and rbcL consistently resolved 15 species (75%) into monophyletic groups and five species into two paraphyletic groups. The 173 ITS sequences, including 138 cloned sequences from 23 accessions, discriminated only 12 species (60%), and the remaining species were entered into three paraphyletic groups. Phylogenetic and genealogic analyses of plastid and ITS sequences imply the possible occurrence of natural hybridizations in the evolutionary past in giving rise to species paraphyly and intragenomic ITS heterogeneity in the species tested. The results support using matK and rbcL loci for barcoding Zingiberaceae members and highlight the poor utility of ITS and the highly regarded ITS2 in barcoding this family, and also caution against proposing ITS loci for barcoding taxa based on limited sampling.

Rhynchanthus beesianus (Zingiberaceae) has been an important food spice and vegetable in southern China. Fifteen phenolic compounds (1–15) including three new diarylheptanoids, rhynchanines A–C (1–3) and one new phenylpropanoid, 4-O-methylstroside B (9), were isolated from R. beesianus rhizomes. The structures of new compounds were elucidated by comprehensive analyses through NMR, HRMS technique, acid hydrolysis, and Mosher’s reaction. Among them, compound 5 is the first isolated natural product and its NMR data are reported. Most of the isolated compounds, especially 3–6 and 8, showed significant antioxidant activities on DPPH, ABTS+ radical scavenging, and FRAP assays. Furthermore, the antioxidant phenolic compounds were evaluated for their cytoprotective capacity against H2O2-induced oxidative stress in HepG-2 cells. Compounds 3 and 5 could significantly inhibit reactive oxygen species production, and compounds 3, 5, and 6 could remarkably prevent the cell apoptosis. Then, the R. beesianus rhizome, which contained phenolic compounds, might serve as a functional food for potential application on preventing oxidative stress-connected diseases.

Rhynchanthus beesianus is a medicinal, ornamental, and edible plant, and its essential oil has been used as an aromatic stomachic in China. In this study, the chemical constituents, antibacterial, and anti-inflammatory properties of flower essential oil (F-EO), leaf essential oil (L-EO), and stem essential oil (S-EO) of R. beesianus were investigated for the first time. According to the GC-FID/MS assay, the F-EO was mainly composed of bornyl formate (21.7%), 1,8-cineole (21.6%), borneol (9.7%), methyleugenol (7.7%), β-myrcene (5.4%), limonene (4.7%), camphene (4.5%), linalool (3.4%), and α-pinene (3.1%). The predominant components of L-EO were bornyl formate (33.9%), borneol (13.2%), 1,8-cineole (12.1%), methyleugenol (8.0%), camphene (7.8%), bornyl acetate (6.2%), and α-pinene (4.3%). The main components of S-EO were borneol (22.5%), 1,8-cineole (21.3%), methyleugenol (14.6%), bornyl formate (11.6%), and bornyl acetate (3.9%). For the bioactivities, the F-EO, L-EO, and S-EO exhibited significant antibacterial property against Bacillus subtilis, Enterococcus faecalis, Staphylococcus aureus, Proteus vulgaris, Pseudomonas aeruginosa, and Escherichia coli with the inhibition zones (7.28–9.69 mm), MIC (3.13–12.50 mg/mL), and MBC (6.25–12.50 mg/mL). Besides, the F-EO, L-EO, and S-EO significantly inhibited the production of proinflammatory mediator nitric oxide (NO) (93.15–94.72%) and cytokines interleukin-6 (IL-6) (23.99–77.81%) and tumor necrosis factor-α (TNF-α) (17.69–24.93%) in LPS-stimulated RAW264.7 cells at the dose of 128 μg/mL in the absence of cytotoxicity. Hence, the essential oils of R. beesianus flower, leaf, and stem could be used as natural antibacterial and anti-inflammatory agents with a high application potential in the pharmaceutical and cosmetic fields.
