چکیده
What is CNSL? Cashew nut Shell Liquid (CNSL) is a reddish brown viscous liquid, having the honeycomb structure of the shell of cashew nut obtained from cashew tree. Botanical name of Cashew: Anacardium occidentale L CAS number: 8007-24-7 Area of growth of Cashew tree Coastal areas of Asia and Africa. Mozambique, India, Vietnam and Brazil Specification of Cashew nut shell The shell is about 0.3 cm thick, having a soft feathery outer skin and a thin hard inner s kin. Between these skins is the honeycomb structure containing the phenolic material known as CNSL. Inside the shell is the kernel wrapped in a thin skin known as the testa. Composition of cashew nut The nut consists of the following: Kernel 20 to 25% Kernel liquid 20 to 25% Testa 2% Others Rest being the shell.

متن کاملEvaluation of Toxic, Cytotoxic, Mutagenic, and Antimutagenic Activities of Natural and Technical Cashew Nut Shell Liquids Using the Allium cepa and Artemia salina Bioassays
The cashew nut releases a substance that is known as cashew nut shell liquid (CNSL). There are both natural (iCNSL) and technical (tCNSL) cashew nut shell liquids. This study used an Artemia salina bioassay to evaluate the toxic effects of iCNSL and tCNSL cashew nut shell liquids. It also evaluated the toxicity, cytotoxicity, and mutagenicity of CNSL and its effects on the damage induced by cop...
