- Carcinogenesis
- 1 February 1985
In order to evaluate exposure of betel quid chewers to N-nitroso compounds, saliva and urine samples were collected from chewers of betel quid with or without tobacco, from tobacco chewers, from… Expand
Correlation of mutagenicity and tumorigenicity of betel quid and its ingredients.

- Nutrition and cancer
- 1983
The mutagenic activity of betel quid and its ingredients was determined using Salmonella typhimurium tester strains TA 100, TA 1535, TA 98, and TA 1538, both in the presence and absence of S9… Expand

Food additives such as turmeric (Curcuma longa), and active ingredient curcumin (diferuloyl methane), asafoetida (flavouring agent), butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT) and… Expand
Effect of turmeric oil and turmeric oleoresin on cytogenetic damage in patients suffering from oral submucous fibrosis.
In vitro studies on the effect of alcoholic extracts of turmeric (TE), turmeric oil (TO) and turmeric oleoresin (TOR), on the incidence of micronuclei (Mn) in lymphocytes from normal healthy subjects… Expand
Antimutagenic effects of betel leaf extract against the mutagenicity of two tobacco-specific N-nitrosamines.
- P. R. Padma, A. Amonkar, S. Bhide
- Biology, Medicine
- Mutagenesis
- 1 March 1989
Epidemiological studies have implicated chewing tobacco alone to be more hazardous than chewing tobacco with betel quid. Experimental studies have shown that betel leaf is antimutagenic against… Expand
Hydroxychavicol: a new phenolic antimutagen from betel leaf.

- Chemistry, Medicine
- Food and chemical toxicology : an international…
- 1 December 1986
The phenolic compounds eugenol and hydroxychavicol were separated from betel leaf extract using C18 phase bonded Hiflosil silica gel. The structures of the two compounds were confirmed by nuclear… Expand

- Biology, Medicine
- Cancer letters
- 1 August 1987
Ginger extract and its constituents gingerol, shogaol and zingerone were tested in Salmonella typhimurium strains TA 100, TA 98, TA 1535 and TA 1538 in the presence and in absence of S9 mix. It was… Expand
Mutagenicity of betel quid and its ingredients using mammalian test systems.

- 1 April 1984
The mutagenic potential of betel quid and its ingredients (known colloquially as PAN) were tested in two short term mutagenicity assays, the micronucleus test and a mammalian gene mutation test.… Expand
Anticarcinogenic effect of betel leaf extract against tobacco carcinogens.
- P. R. Padma, V. Lalitha, A. Amonkar, S. Bhide
- Medicine
- Cancer letters
- 1 June 1989
Epidemiological studies have implicated that betel quid offers some protection to tobacco induced carcinogenesis. Earlier studies in our laboratory have shown betel leaf extract (BLE) to be… Expand
Mutagenicity of chili extract and capsaicin in short-term tests.
