The effect of Psidium guajava extract on erythromycin-induced liver damage in albino rats was investigated using 30 normal rats grouped into six. Group I and II served as the normal and treatment controls that were administered with normal saline and 100 mg/kg body weight of erythromycin stearate daily for 14 days respectively. Rats in group III were administered 450 mg/kg body weight of Psidiu...

Antimicrobial activity of 25, 50, 75 and 100% alcohol extract of Piper nigrum (Black Pepper), Psidium guajava (Guava), Amomum cardamom (Cardamom) and Cynogen dactylon (Bermuda grass) has been evaluated against Pseudomonas lundensis, Bacillus cereus, Aspergillus niger and Aspergillus flavus. Psidium guajava extract showed excellent antimicrobial activity against all the test organisms. In 25% co...

Psidium guajava L is commonly known as guava in English. The present investigation focuses on the toothache activity. The investigation is based upon the analgesic, anti-inflammatory and anti-microbial activity of water extract of Psidium guajava L. The study assessed the different solvent extracts of Psidium guajava leaf for thin layer chromatography (TLC) and also evaluated the analgesic acti...

Aegle marmelos, Bilwa (AM) and Psidium guajava, Guava, (PG) leaves were screened for phytochemicals by sequential extraction using a series of solvents. The antioxidant components such as β-carotene, α-Tocopherol, glutathione, ascorbic acid, total polyphenols and flavonoids were also analyzed. In addition, the leaves were extracted with methanol (ME), ethanol (EE) and water (WE) and the polyphe...

The present study investigates the interaction of aqueous leaf extract of Psidium guajava with muscarinic, serotonergic and adrenergic receptor system using isolated rat ileum, gastric fundus and trachea, respectively. The concentration-dependent contractile response of aqueous leaf extract of Psidium guajava was parallel and rightward of standard agonists, ACh and 5-HT indicating agonistic act...

A (GA) n and (GT) n microsatellite-enriched library was constructed and 23 nuclear simple sequence repeat (SSR) loci were characterized in the guava species ( Psidium guajava L.). All SSR loci were found to be polymorphic after screening for diversity in different cultivars, and across-taxa amplification tests showed the potential transferability of most SSR markers in three other Psidium speci...

Guava (Psidium guajava L.) crop is severely affected by the nematode Meloidogyne enterolobii. Native Psidium species have been reported as sources of resistance against this nematode. Knowledge on the molecular relationship between Psidium species based on plant resistance gene analogs (RGA) can be useful in the genetic breeding of guava for resistance to M. enterolobii. In this study, RGA mark...

This study aims to present the in vitro inhibitory effect of Psidium guajava and Juglans regia leaf extracts on the main developer of acne lesions, Propionibacterium acnes (P. acnes), and other organisms that are isolated from acne lesions. Thirty-eight subjects (males and females) who had various types of acne were enrolled in the study. The contents of the acne lesions were cultured and the f...

BACKGROUND Psidium guajava is commonly known as guava. Psidium guajava is a medium sized tree belonging to the family Myrtaceae found throughout the tropics. All the parts of the plant, the leaves, followed by the fruits, bark and the roots are used in traditional medicine. The traditional uses of the plant are Antidiarrheal, Antimicrobial Activity, Antimalarial/Antiparasitic Activity, Antituss...

Background The Psidium guajava, commonly known as the apple guava, has shown various biological activities related to its main constituents, such as flavonoids, carotenoids, terpenoids and phenolic compounds. Studies emphasize antispasmodic and antimicrobial properties in the treatment of diarrhea and dysentery. It also has hypoglycemiant, antioxidant, hepatoprotective, anti-allergic, antimicro...
