Abstract

matK is one of the universal loci which is commonly used as a barcode in the molecular identification of plants. Up to now, the problem of matK as a single locus is the use of the entire gene region as barcodes. The long amplicon size of matK raises several problems in DNA barcoding. The aim of this study is to uncover a small region of the matK gene as a potential mini-barcode region for alternative sites to get more efficient and effective results. In silico studies performed include the collection of matK sequence of medicinal orchid from GenBank, the amplicon size from matK primer sets that are commonly used in the Orchidaceae family, and PCR analysis. Data analysis was done by comparing the results of PCR amplification from several primer sets: matK 390F-1326R, 743F-R2, 712F-1154R and 712F-1216R. The results show that all primer pairs are able to amplify the DNA template isolated from Dendrobium purpureum. However, the shorter DNA band obtained from matK 743F-R2, 712F-1154R and 712F-1216R primers sets were visualized more thick than the longer amplicon band produced from matK primer 390F-1326R. This indicates that short matK sequence for DNA barcoding (mini-barcode) is more efficient in amplifying DNA templates compared to generally applied barcoding using full length sequences.

Abstract

Ranunculus japonicus has been traditionally used to treat various ailments, including malaria, jaundice, gastric problems, toothache, and eye inflammation. Recent studies reported that the plant extract effectively treat rheumatoid arthritis due to its secondary metabolites with antioxidant activities, such as flavonoids and phenols. In this study, we analyzed the flavonoids and phenols from R. japonicus using in silico methods. The study determined the flavonoid and phenol contents based on existing literature. The antioxidant potential analysis was conducted using PASS (Prediction of Activity Spectra for Substances). The results indicate the presence of two flavonoid compounds, namely Apigenin 6,8-di-C-|A-L-Arabinopyranoside and 3-Methylquercetin, and three phenol compounds, namely 3-Hydroxytrisol 3-O-glucoside, 4-Hydroxy-3-methoxyacetate, and Hydroxytrisol. Two compounds exhibited high bioactive potential (Pa value > 0.7), two compounds showed medium bioactive potential (Pa value > 0.5), and one compound exhibited low bioactive potential (Pa value < 0.5). The most bioactive compounds were Apigenin 6,8-di-C-|A-L-Arabinopyranoside and 3-Methylquercetin. The compounds with medium bioactivity were 3-Hydroxytrysol 3-O-glucoside and 4-Hydroxy-3-methoxycinnamic. The PASS online analysis revealed the potential of antioxidants for medicinal potencies
