Allergic has been suspected to relate with immunoglobulin E (IgE) formation, followed by the release of histamine and other cells mediator, until the symptom occur. In this research, the effect of ovalbumin induction on allergic reaction was studied. The used guinea pigs were divided into control (K) and ovalbumin treatment groups, each containing three guinea pigs. Animals were adapted for 14 days then 40 days albumin induced for allergic reaction. Guinea pig’s blood were taken after 40 days sensitization and injected back (anafilaksis cutaneous pasif) to the animals. Evans blue were given after 48 hours serum injection, to obtain bluish spot formation for symptom observation. Research showed that ovalbumin induced allergic reaction.

Each groups were comprised three guinea pigs and all of it were adapted for 14 days. Guinea pigs were sensitized for 39 days with egg white 2 mg/mL dissolved by Al(OH)3 as adjuvant and buffer saline by forced egg white down. While, another three guinea pigs were adapted for 3 days to determine pharmacologic dosage based Lethal Dose 50 (LD50) of Quercetin. The result of this assay showed that at dose 13.92 mg/kg body weight is safe dosage. This dosage then used for determine the effect of quercetin as antiallergy with Evans blue dye as indicator (AKP method). The result of AKP showed that quercetin has no significant effect.
