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 Eclipta prostrata (L).[Pubmed:
12579857]
To study the chemical constituents of Eclipta prostrata (L).
METHODS AND RESULTS:
The constituents of E. prostrata were systematically separated with the Bohlmann method and percolation and hot extraction methods, and various chromatographies. The structures were elucidated by chemical and spectroscopic means. RESULTS: Ten compounds were isolated from the Eclipta prostrata. Their structures were determined as wedelolactone (1), demethylwedelolactone (2), Isodemethylwedelolactone (3), alpha-formylterthienyl (4), strychnolactone (5), beta-sitosterol (6), nonacosanol (7), stearic acid (8), lacceroic acid (9), 3,4-dihydoxy benzoic acid (10). Fourteen ocmpounds, including hydrocarbons and its esters were identified by GC-MS from the least polar fractions.
CONCLUSIONS:
Compound 3 is a new coumestan named Isodemethylwedelolactone. Compounds 2-10 and compounds characterized by GC-MS analysis were obtained for the first time from Eclipta prostrata.
