Abstract:
A high activity of molting hormone (ecdysone) was detected in the extract of unfertilized, diapausing and developing silkworm eggs. The active substance in the diapause eggs behaved as a highly polar molecule at partitioning between n-butanol and water, and also in TLC. The majority of the activity seems to be due to a conjugated ecdysone, since the polar active substance was changed to a less polar substance upon treatment with "snail enzymes".
