The published data were based only on school children and adolescents.19 The prevalence of RE in Saudi adults of Arar city is 45.8% which is lower than the prevalence of RE (72.2%) among female students of Medicine and Pharmacy Schools in
Quassin University as reported by Albatanony.20 Another study from Quassim estimated the prevalence of RE as 58.6% among the male medical students of Qassim University.17

The two main ingredients are
quassin and neoquassin.
donovani fraction - Singh et al.(2005) Quassia amara Quassin L.
Quassin isolated from Quassia amara enhanced the host protective immune response by enhancing generation of NO and expression of iNOS both at a protein and at mRNA levels and by upregulating proinflammatory cytokines, TNF-[alpha] and IL-12 (Bhattacharjee et al.
amara extracts, in which quassinoids such as quassin and neoquassin possibly predominate (Polonsky 1973) and there are also some carboline and related alkaloids (Barbetti et al.
For example, quassin is soluble in polar solvents like methanol and non-polar solvents like benzene and acetone but not in other non-polar solvents, such as diethyl ether (Budavari 1989); consequently, it is likely that the methanol fraction contained quassin, which caused phagodeterrence.
* For alcoholic drinks--beta-asarone (1 mg/kg); quassin (1.5); teucrin A (2); hydrocyanic acid (35); quassin (1.5); and thujone alpha and beta (10, with 35 for vermouth and absinthe);
* Non-alcoholic drinks--1-Allyl-4-methoxybenzene (10); quassin (0.5); 4-Allyl-1,2-dimethoxybenzene (1); and 1-Allyl-3,4-methylene dioxy benzene, safrole (1).
Deterrence could be explained by the presence of quassinoids, such as
quassin and neoquassins, which are common in Q.
* Other limits for hydrocyanic acid; 4-Allyl-1,2-dimethoxybenzene; Pulegone;
Quassin; and 1-Allyl-3,4-methylene dioxy benzene, safrole.
