Areca nut (seed of Areca catechu) is consumed by people from different parts of Asia, including India. The four major alkaloids present in areca nut are arecoline, arecaidine, guvacoline and guvacine. Upon cutting, the nut reveals two kinds of regions; white and brown. In our present study, we have
The dichloromethane fraction from Areca catechu was found to inhibit monoamine oxidase type A isolated from the rat brain with an IC50 of 665 +/- 65.1 microg/ml. Studies with pharmacological models of depression, i.e., forced swim and tail-suspension tests, indicated that it caused significant
Arecaidine and guvacine, constituents of the nut of Areca catechu, inhibited the uptake of GABA and beta-alanine, but not that of glycine, by slices of cat spinal cord. In cats anesthetised with pentobarbitone, electrophoretic arecaidine enhanced the inhibitory actions of GABA and beta-alanine, but
Raw Arecae Semen, the seed of Areca catechu L., as well as Arecae Semen Tostum and Arecae semen carbonisata are traditionally processed by stir-baking for subsequent use in a variety of clinical applications. These three Arecae semen types, important Chinese herbal drugs, have been used in China and

The use of betel quid is the most understudied major addiction in the world. The neuropsychological activity of betel quid has been attributed to alkaloids of Areca catechu. With the goal of developing novel addiction treatments, we evaluate the muscarinic and nicotinic activity of the
Arecoline (methyl-1,2,5,6-tetrahydro-1-methyl nicotinate) is an alkaloid found in the areca catechu nut which is a major component of the 'betel quid' chewed by a large proporation of the population in India, South Asia and the South Pacific islands. It is commonly associated with the development of
Areca nuts (seeds of Areca catechu L.) are a traditional and popular masticatory in India, Bangladesh, Malaysia, certain parts of China, and some other countries. Four related pyridine alkaloids (arecoline, arecaidine, guvacoline, and guvacine) are considered being the main functional ingredients in
Betel nut is the fruit of Areca palm, growing in Papua New Guinea. Mixed with limestone and stick mustard, arecoline and guvacoline, which are present in betel nut, are hydrolyzed into arecaidine and guvacine, respectively. As part of the study on dietary habits of Papuans residents, our laboratory
An improved high-performance liquid chromatography (HPLC) method was established to rapidly and simultaneously determine 3 main alkaloids (arecoline, arecaidine, and guvacine) in areca (betel) nuts (AN), and 12 AN samples from the main betel palm growing areas on the Chinese Mainland were collected
BACKGROUND
The Areca catechu Linn. is the fourth most used drug in the world after nicotine, ethanol and caffeine. This plant contains nine alkaloids with muscarinic and nicotinic action, which could have an antipsychotic effect.
OBJECTIVE
The aim of this work is reviewing literature data about the
Oral submucous fibrosis (OSF) is characterized by excessive collagen production by mucosal fibroblasts and is associated with the habitual chewing of betel-nuts (Areca catechu); nut extracts stimulate fibroblast activity in vitro. The metabolism of arecoline, the major alkaloid in the nut, by human
