as seed germination of guava (psidium guajava) is poor and time-consuming, the effects of seed extraction technique and scarification methods on the seed germination and seedling growth of guava cv. allahabad safeda, were investigated. first experiment was conducted on extraction of guava seeds using sulfuric acid (h2so4) : seed ratios including: 1:5, 2:5 and 3:5) or manual extraction (control)...

One plant seed extract (Psidium guajava) was screened for their bioreduction behavior for synthesis of silver nanoparticles. Psidium guajava (PG) was found to exhibit the good reducing and protecting action in terms of synthesis rate and monodispersity of the prepared silver nanoparticles. UV–visible spectroscopy, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), transmis...

The aqueous extracts of Piper betle and Psidium guajava were prepared and tested for their anti-adherence effect on the adhesion of early plaque settlers (Strep. mitis, Strep. sanguinis and Actinomyces sp.). The saliva-coated glass surfaces were used to simulate the pellicle-coated enamel surface in the oral cavity. Our results showed that the anti-adherence activities of Piper betle and Psidiu...

Objectives: To study the anti-convulsant potential of leaves of Psidium guajava Linn. in MES and PTZ induced convulsion in experimental animals. Materials and methods: The anticonvulsant potential of the ethanolic extracts of Psidium guajava Linn. (EEPG) were tested in the mice model of Maximal electroshock (MES) and Pentylenetetrazole (PTZ). In the MES model, seizures were induced by deliverin...

Guava (Psidium guajava L.), a tropical fruit, belongs to Myrtaceae family. Leaves and fruits of guava have been reported to have an anti-diarrheal, hypoglycemic, lipid lowering, anti-bacterial in addition to antioxidant activities. The aim of this study was to investigate several guava leaf extract cytotoxic effects on healthy clone 9 liver cells and its hepatoprotective effects on ethanol-indu...

Introduction: Fruit polysaccharides, essential health factors in foods, are widely present in edible fruits. Several methods for isolation of polysaccharide are available. Microwave Assisted Extraction (MAE) method is extensively used for separation of polysaccharides. Only little information is available about Psidium guajava L. Fruit Polysaccharide (PFP) and its extraction methods. Objective:...

Guava (Psidium guajava) is known as Peruka or Paravata in samskrit. In ayurveda it is considered as tridosha nashaka, and indicated in atyagni. Its leaves, bark, fruits and roots are used in treatment of cough, fever, diarrhea, constipation, bad breath, gum problems and numerous other health problems. It is hepatotonic and thus good for liver, digestive system, heart and intestine. Guava can al...

Hexane, ethyl acetate, ethanol and methanol extracts of Psidium guajava, Terminalia chebula, Mimusops elengi and Achyranthes aspera were tested against the dental caries causing bacteria Streptococcus mutans and fungus Candida albicans isolated from caries infected patients. All the four extracts of P. guajava showed activity against both S. mutans and C. albicans. Maximum zone of inhibition wa...

Growing rates of fungal infections and increasing resistance against standard antifungal drugs can cause serious health problems. There is, therefore, increasing interest in the potential use of medicinal plants as novel antifungal agents. This study investigates the antifungal properties of crude plant extracts from ten medicinal plant species. Crude samples were extracted using the hot water ...
