soda ash and 5% aqueous sodium carbonate were used to isolate and purify gibberellin-like substances from the tissue of bean seedlings. This method has several distinct advantages compared to extraction methods using organic and aqueous solvents alone. The extract is prepared more quickly and the separation and purification are done easily. The hydroxy keto gibberellic compound was isolated with 100% purity and identified using proton and carbon nuclear magnetic resonance spectroscopy.
