Metabolomics-Driven Discovery of an Introduced Species and Two Malaysian Piper betle L. Variants.

ABSTRACT: The differences in pungency of "sirih" imply the probable occurrence of several variants of Piper betle 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 P. betle variants were thus investigated; specifically, the leaf aqueous methanolic extracts and essential oils were analyzed via ¹H-NMR and GC-MS metabolomics, respectively. Principal component analysis (PCA) of the ¹H-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 Piper rubro-venosum 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 P. betle 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 P. betle variants in Malaysia based on chemical profiles, which may be related to the different genders of P. betle.

A new hydroxychavicol dimer from the roots of Piper betle.

Project description:A new hydroxychavicol dimer, 2-(g'-hydroxychavicol)-hydroxychavicol (1), was isolated from the roots of Piper betle Linn. along with five known compounds, hydroxychavicol (2), aristololactam A II (3), aristololactam B II (4), piperolactam A (5) and cepharadione A (6). The structures of these isolated compounds were elucidated by spectroscopic methods. Compounds 1 and 2 exhibited inhibitory effects on the generation of superoxide anion and the release of elastase by human neutrophils.

Novel Amides Derivative with Antimicrobial Activity of Piper betle var. nigra Leaves from Indonesia.

Project description:Piper betle var. nigra is a tropical plant closely related to the common piper. P. betle has also been dubbed a promising source of natural antioxidants in herbal health products, antibacterial, antifungal, antimalarial, cytotoxic activity against the cancer cell lines K562 and HL-60, and antileishmanial. The aim of this study to observation Antimicrobial activity and isolation of chemical compound. The antimicrobial activity of P. betle extract was performed by well diffusion method against two oral pathogenic bacteria (Streptococcus mutans and Streptococcus sanguinis) and opportunistic pathogenic yeast (Candida albicans). The inoculum (bacterial and yeast suspension) was prepared from a 24-h culture on NB for bacterial suspension and on TSB for yeast suspension. Extraction and isolation using various method of chromatography. Isolated compounds were characterized by spectroscopic means. Our study showed antimicrobial activity from crude ethanol extract of leaves P. betle L. var. nigra against two oral pathogenic bacteria and opportunistic pathogenic yeast with concentration 0.5% and 1%. The first report of two new amides derivatives, piperenamide A (1) and piperenamide B (2) in P. betle L. var. nigra.

Evaluation of antifertility potential of Piper betle (Petiole) on female wistar rats "rising approaches of herbal contraception''.

Project description:Piper betle (Petiole) is used of herbal methods for fertility regulation is widely accepted alternative for the synthetic drugs containing chemical having side effects. Piper betle (Petiole) is the plant having several medical properties but no reports were available on the antifertility activity. The aim of this study was to investigate the antifertility activity of extracts of Piper betle (Petiole) on female wistar rats at the doses 500?mg/kg b.wt./day for 30 days. Different parameters were studied in female wistar rats including effect of Reproductive outcome, Anti-implantation, Abortifacient and Estrogenic & Anti-estrogenic activity, were observed. Piper betle shown positive test for Alkaloids, Steroid, Flavonoids, Terpene, Carbohydrates and Tannin. The extract has anti-fertility effect the control rats showed good number of litters and treatment of animal with different extracts resulted a significant (P?<?0.05, P?<?0.01). Antifertility activity 51% and 37.2% was exhibited by Alcoholic extracts of Piper betle (Petiole) APB and Aqueous extracts of Piper betle (Petiole) WPB respectively. After 21 days of the extracts free period, the antifertility effect of the extracts was reversed. The extract treatment with APB, an increase in the percentage of resorption index indicates the failure in development of embryo. The mean percentage of anti-implantation and abortifacient were found to be highest for APB-38.45%, WPB 13.62, and APB-28.96%, WPB-12.75% respectively. The decrement in implantation caused by the extracts may be due to estrogenic or anti-estrogenic activity. However, along with standard APB exhibiting more potent estrogenic and less potent anti-estrogenic when compared with standard. Female antifertility agents should include acceptability, safety and efficacy during and after the treatment. The above results revealed the potential, reversible female antifertility effect of alcoholic extract Piper betle (Petiole).

Anti-migratory effects of Piper betle leaf aqueous extract on cancer cells and its microtubule targeting properties.

Project description:Piper betle (PB), also known as "betel" in Malay language, is a tropical Asian vine. PB leaves are commonly chewed by Asians along with betel quid. It contains phenols such as eugenol and hydroxychavicol along with chlorophyll, β-carotene, and vitamin C (Salehi et al., 2019). Extracts from PB leaves have various medicinal properties including anticancer, antioxidant, anti-inflammatory, and antibacterial effects (Salehi et al., 2019). Previous research has shown that PB induces cell cycle arrest at late S or G2/M phase and causes apoptosis at higher doses (Wu et al., 2014; Guha Majumdar and Subramanian, 2019). A combination of PB leaf extract has also been shown to enhance the cytotoxicity of the anticancer drug, 5-fluorouracil (5-FU), in cancer cells (Ng et al., 2014).

Effects of Piper betle L. Extract and Allelochemical Eugenol on Rice and Associated Weeds Germination and Seedling Growth.

Project description:Natural herbicide is considered as a sustainable approach for weed management in agriculture. Here, allelopathic activities of Piper betle L. extract (BE) and known allelochemical eugenol (EU) were studied against rice and associated weeds in terms of germination and seedling growth. Five plant species including a rice crop (Oryza sativa L.); a dicot weed, false daisy (Eclipta prostrata (L.) L.); and three monocot weeds, barnyard grass (Echinochloa crus-galli (L.) P. Beauv.), swollen fingergrass (Chloris barbata Sw.), and weedy rice (Oryza sativa f. spontanea Roshev.) were studied. The paper-based results demonstrated that BE and EU had inhibitory effects on seed germination and seedling growth. The IC50 values of BE and EU for seed germination were ranked from swollen fingergrass, to false daisy, barnyard grass, rice, and weedy rice, respectively. The ratio of root to shoot length of the seedlings indicated that the roots were more affected by the treatments than the shoots. In addition, the gel-based results showed the reduction of the rice seedling root system, especially on lateral root length and the numbers upon the treatments. Taken together, BE had an allelopathic activity similar to that of EU. Interestingly, the major paddy weed, barnyard grass, was more sensitive to BE than rice, underlining BE as a natural herbicide in rice agriculture.

Piper betle leaf extract affects the quorum sensing and hence virulence of Pseudomonas aeruginosa PAO1.

Project description:Quorum sensing (QS) plays an important role in virulence of Pseudomonas aeruginosa, blocking of QS ability are viewed as viable antimicrobial chemotherapy and which may prove to be a safe anti-virulent drug. Bioactive components from Piper betle have been reported to possess antimicrobial ability. This study envisages on the anti-QS properties of ethanolic extract of P. betle leaf (PbLE) using P. aeruginosa PAO1 as a model organism. A marked reduction in swarming, swimming, and twitching ability of the bacteria is demonstrated in presence of PbLE. The biofilm and pyocyanin production also shows a marked reduction in presence of PbLE, though it does not affect the bacterial growth. Thus, the studies hint on the possible effect of the bioactive components of PbLE on reducing the virulent ability of the bacteria; identification of bioactive compounds should be investigated further.
