Purification and separation of eight steroidal plant-growth regulators from Dolichos lablab seed.

Abstract

Purification and separation of eight steroidal plant-growth regulators, dolicholide, dolichosterone, homodolicholide, homodolichosterone, brassinolide, castasterone, 6-deoxocastasterone and 6-deoxodolichosterone, from immature seed of Dolichos lablab were accomplished using various chromatographic techniques. The reversed-phase HPLC of a number of steroidal plant growth regulators was also studied.
