Anti-plaque activity of Piper betle leaf extracts

An effort to prevent aquatic fungi Aphanomyces sp. infection on fish using natural material can be an economically way, easy to find the materials, easy to apply and safe for environment. The antifungal potency and efficacy of scalded-leaf extract of Terminalia cattapa, Piper betle, Psidium guajava and Andrographis peniculata on prevention of Aphanomyces sp. growth in vitro in GYA medium. Scalding was performed in the water at 50°C. Concentration of leaf extracts tested was 0, 10, 20, 40 and 80 g/L. The results of study showed that Terminalia cattapa in a dosage of 40 g/L had the best prevention activity, followed by Piper betle in the same dosage. Psidium guajava and Andrographis peniculata had no prevention activity on growth of Aphanomyces sp. Keywords: antifungal, Terminalia cattapa, Piper betle, Psidium guajava, Andrographis peniculata growth, Aohanomyces sp. ABSTRAK Upaya penanggulangan infeksi cendawan akuatik Aphanomyces sp. pada ikan menggunakan bahan alami dapat menjadi cara yang ekonomis ekonomis, bahan mudah didapat, mudah diterapkan dan aman bagi lingkungan. Potensi antifungi dan efektivitas ekstrak seduh daun ketapang (Terminalia cattapa), sirih (Piper betle), jambu biji (Psidium guajava) dan sambiloto (Andrographis peniculata) terhadap penghambatan pertumbuhan Aphanomyces sp. dilakukan secara in vitro dalam media biakan GYA. Penyeduhan dilakukan menggunakan pelarut air dengan suhu 50°C. Konsentrasi yang diuji adalah 0, 10, 20, 40 dan 80 gr/L untuk masing-masing bahan. Aktivitas penghambatan paling baik terhadap cendawan diperoleh dari ekstrak seduh daun ketapang 40 g/L dan diikuti oleh ekstrak seduh daun sirih dengan konsentrasi yang sama. Jambu biji dan sambiloto tidak menunjukkan aktivitas penghambatan terhadap pertumbuhan Aphanomyces sp. Kata kunci: antifungi, ketapang, sirih, jambu biji, sambiloto dan Aphanomyces sp.

The effect of leaf extracts ofPsidium guajavaandPiper betleon prolonging vase life of cut carnation flowers was studied. “Carola” and “Pallas Orange” carnation flowers, at bud stage, were pulsed 24 hours with a floral preservative. Then, flowers were placed in a vase solution containing sprite and a “germicide” (leaf extracts ofP. guajavaandP. betle, 8-HQC, or a copper coin). Flowers treated with 8-HQC, copper coin, and leaf extracts had longer vase life, larger flower diameter, and higher rate of water uptake compared to control (tap water). The leaf extracts ofP. guajavaandP. betleshowed highest antibacterial and antifungal activities compared to the other treatments. Both showed similar effects on flower quality as the synthetic germicide, 8-HQC. Therefore, these extracts are likely natural germicides to prolong vase life of cut flowers.

Chitosan Hydrolysis

Green betel leaf (Piper betle L.) is one of the plants being used for traditional herbal medicine. This study aimed to determine betel leaf extract-chitosan nanoparticles to control anthracnose disease on mango. Chitosan nanoparticles were prepared by ionic gelation method using sodium tripolyphosphate as cross-linking agent. Characterization of the betel leaf extract was done by pyrolysis GC-MS; while chitosan nanoparticles were characterized using FTIR spectroscopy, SEM, and PSA analysis. The results showed that the green betel leaf extract contains 71.18 + 0.3% of antifungal phenolic compounds. The most phenolic compounds and their derivatives in the betel leaf extract was 1-hydroxy-4-methylbenzotriazole. Chitosan hydrolysis reduced the chitosan MW from 754.89 kDa to 245.85 kDa. Based on FTIR analysis, hydrolysis treatment and the addition of extract affected the existence of chitosan functional group, and wave numbers. The absorption of aromatic groups was observed at 1000 - 650 cm-1 wave numbers. The sizes of particle were ranged from 101 + 6.25 nm to 431.1 + 4.32 nm. The size of chitosan without hydrolysis was bigger than that of chitosan with hydrolysis. The SEM morphology of the chitosan nanoparticle-betel leaf extract was spherical shape. Chitosan hydrolysis treatment had a higher antifungal effect than that of chitosan without hydrolysis. The mass ratio of chitosan nanoparticles and betel leaf extracts (3:1; v/v) of both without hydrolysis and with hydrolysis was found as a good formula in suppressing anthracnose on mangoes with the degree of disease inhibition of 85.88% and 98.82%, respectively. The betel leaf extract-loaded chitosan nanoparticle treatment may offer the fruit shelf life up to 6 days.
