Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to
24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

Studies on the chemical constituents of Rutaceae++ plants. LXVI. The chemical constituents of Toddalia asiatica (L.) Lam. (T. aculeata Pers.). (1). Chemical constituents of the root bark.[Pubmed:
1783985]
Chemical constituents of the root bark of Toddalia asiatica (L.) Lam. (T. aculeata Pers.), Rutaceae, were examined.
METHODS AND RESULTS:
In addition to twelve known coumarins [toddaculin (2), coumurrayin (5), toddanone (6), 8-(3,3-dimethylallyl)-6,7-dimethoxycoumarin (7), isopimpinellin (8), 6-(3-chloro-2-hydroxy-3-methylbutyl)-5,7-dimethoxycoumarin (9), 6-formyllimettin (10), 5,7,8-trimethoxycoumarin (12), toddasin (13), (+)-toddanol (14), 6-(2-hydroxy-3-methoxy-3-methylbutyl)-5,7-dimethoxycoumarin (18), and toddalolactone (21)] five new coumarins [toddalenol (17), toddalosin (19), 5-Methoxysuberenone (23), toddalenone (24), and 8-formyllimettin (25)] were isolated.
CONCLUSIONS:
Furthermore seven known benzo[c]phenanthridine alkaloids [des-N-methylchelerythrine (4), oxychelerythrine (15), arnottianamide (16), oxyavicine (22), avicine (30), chelerythrine (31), and chelerythrine-psi-cyanide (34)] and four known quinoline alkaloids [N-methylflindersine (11), 4-methoxy-1-methyl-2-quinolone (20), skimmianine (35), integriquinolone (36)], one known triterpenoid [beta-amyrin (3)], and four unknown components [unknown I-IV (26)-(29)] were isolated.
