Location by paper chromatography of compensatory ovarian hypertrophy (COH) inhibiting activity in isobutanol extracts of bovine pineals.

Bovine pineal glands were extracted according to the methods reported by Bensinger et al. (1973) and Cheesman and Fariss (1970). Isobutanol soluble COH-inhibiting activity was further separated by chromatography on Sephadex G-15 and paper chromatography. With the Bensinger method, different active pineal fractions were obtained from Sephadex G-15 columns. Certain of those fractions were further separated by paper chromatography in butanol : acetic acid : water (4 : 1 : 1) and the COH-inhibitor was localized. The pineal COH-inhibitor could also be localized by high pressure, reverse phase liquid chromatography. More COH-inhibiting activity was extracted with the Bensinger method than with aqueous and acetic acid extraction methods used earlier by us. The Cheesman extraction method for arginine vasotocin gave less regular results in our hands than the Bensinger extraction method.[1]
