Project description:The differences in pungency of 'sirih' imply the probable occurrence of several variants of <i>Piper betle</i> L. in Malaysia. However, the metabolite profiles underlying the pungency of the different variants remain a subject of further research. The differences in metabolite profiles of selected Malaysian <i>P. betle</i> variants were thus investigated; specifically, the leaf aqueous methanolic extracts and essential oils were analyzed via <sup>1</sup>H-NMR and GC-MS metabolomics, respectively. Principal component analysis (PCA) of the <sup>1</sup>H-NMR spectral data showed quantitative differences in the metabolite profiles of 'sirih melayu' and 'sirih india' and revealed an ambiguous group of samples with low acetic acid content, which was identified as <i>Piper rubro-venosum</i> hort. ex Rodigas based on DNA sequences of the internal transcribed spacer 2 (ITS2) region. The finding was supported by PCA of two GC-MS datasets of <i>P. betle</i> samples obtained from several states in Peninsular Malaysia, which displayed clustering of the samples into 'sirih melayu' and 'sirih india' groups. Higher abundance of chavicol acetate was consistently found to be characteristic of 'sirih melayu'. The present research has provided preliminary evidence supporting the notion of occurrence of two <i>P. betle</i> variants in Malaysia based on chemical profiles, which may be related to the different genders of <i>P. betle</i>.
