Test animals

Species:

rat

Strain:

Sprague-Dawley

Sex:

female

Details on test animals or test system and environmental conditions:

Test system: Sprague Dawley rats
Origin: Charles River Laboratories
Source: Facultad de Ciencias Vetcrinarias, Universidad de Buenos Aires, Av. Chorroarin 280, C1427CWO - Buenos Aires, Argentina.
Number of the test animals: 3 Animals. The test was conducted using a single sex (females). Females used were nulliparous and non-pregnant.

Age and weight at the start of the test: Young-adult animals of age 8-12 weeks old, 200-300 g
Body weight: The weight variation in animals used in the test didn t exceed 20% per cent of the mean weight.
Identification: Marks on the tail with inerasable ink
Acclimatization: Animals were acclimatized to laboratory conditions for 10 days before to the start of the test. After acclimatization healthy animals were randomized and assigned to treatment group.

Housing and feeding
Animals were housed under standard laboratory conditions. The experimental animals' room was provided with conditioned air filtered by HEPA filters with 10-15 air changes per hour. The temperature of the animals room was between 22 ± 3°C and the relative humidity between 30-70 per cent, although the upper range for humidity may have exceeded during the cleaning of the room.
Animals were provided with photoperiods of 12 hours light- 12 hours dark and placed into individual cages made of steel with litter of wood shavings.
The following diet was provided ad libitum: Balanced food Rat-Mouse Ganave supplied by Distribuidora Horacio Izaguirre.
Tap water dechlorinated by passage through cartridge of activated charcoal was used ad libitum.

Administration / exposure

Route of administration:

oral: gavage

Vehicle:

water

Details on oral exposure:

Food was withheld the night prior to the administration of the test compound. For the administration of the dose, rigid probes with rounded end were used. The administration volume was 1 ml/100 gr.
After the administration of the test substance, animals were kept unfed for a 3 hour period. Once the substance was administered, observations were made and recorded systematically and individually for each animal.

Remarks:

Migrated information Criteria used for interpretation of results: EU

Conclusions:

The acute oral toxicity of the liquid QUILLAJA EXTRACT QL AGRI, LOTE: 260208-0700 was investigated according to US EPA Guideline EPA OPPTS 870.1100. A group of 3 female Sprague Dawley rats were administered a liquid extract of Quillaja saponaria at a single dose of 5000 mg/kg bw by gavage.
No mortality and no clinical signs of toxicity were obeserved. No abnormalities were recorded durcing necropsies. Therefore the acute oral LD50 value was estimated as > 5000 mg/kg bw.
