Areca quid chewing related oral mucosal lesions are potential hazard to a large population worldwide. Commercially freeze dried products such as pan masala, guthka and mawa have high concentration of areca nut per chew and appear to cause OSMF more rapidly than by self prepared conventional betel quid that contain smaller amounts of areca nut. The basic constituent of areca nut is either raw or...

Oral cancer is the second most common cancer in women and the third most common in men in Pakistan. Tobacco is smoked and chewed extensively in Pakistan. Paan is a quid of piper betel leaf that contains areca nut, lime, condiment, sweeteners, and sometimes tobacco, which is also used extensively.

Tropilaelaps spp. mites are considered a major parasite of honeybees. In this study, essential oils (EOs) 11 plant species were evaluated for acaricidal activity under laboratory and field conditions. Five adult per petri dish ten worker bees plastic cup cage exposed to different concentrations each oil (0.1, 0.5, 1.0, 5.0, 10.0% (v/v)). The Piper betle (betel) showed the highest in testing. Ad...

Chewing betel quid has been linked to the development of oral cancer. In Taiwan, fresh Piper betle inflorescence is uniquely added to betel quid, and hydroxychavicol is the major phenolic components of P.betle inflorescence. In this study, we tested the mutagenic potential of hydroxychavicol in Salmonella typhimurium TA97, TA98, TA100 and TA102 with and without Aroclor-1254 induced S9 fraction....

Accepted: 08/06/2014 Abstract Six variety of betel leaf from different domain of India were extracted using five solvents in order to determine the effect of solvent and changing variety on total phenol content and antioxidant activity. Antioxidant activity was determined using DPPH, ABTS, FRAP, PCL (Photochemluminiscence) assay. However 80% methanol for TPC, 80% ethanol followed by 80% methano...
