Physiological saline, ether, acid ethanolic extracts, and an extract by the Best method were prepared from bovine submaxllary gland but none possessed the action of lowering blood sugar level in a rabbit. The pH 4.5-precipitate, and the fractions which lowered the serum phosphate level and serum calcium level, all obtained from the bovine submaxillary gland were devoid of the action of lowering blood sugar level in rabbits by intravenous injection, as in the case of parotin. The fraction which lowers serum phosphate level in rabbits significantly increased the blood sugar level at a 5% danger rate by subcutaneous injection.
