We use well established data on SN1987A to restrict the coupling gee of the majoron to electronic neutrinos in the Gelmini-Roncadelli model. We exclude values from 10-4 down to 3×10-6. This range is complementary to the expected laboratory limits from next-round experiments, gee≤10-4. If this laboratory bound is reached, we may place the stringent limit gee ≤3 ×10 -6 on the majoron coupling. © 1988.
