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.

Lanostanoids Isolated from Ganoderma lucidum Mycelium Cultured by Submerged Fermentation.[Reference:
WebLink]
METHODS AND RESULTS:
Three new lanostane triterpene acids, 3-O-acetylganoderic acid B (1), 8β,9α-dihydroganoderic acid C (3), and 3-O-acetylganoderic acid K (4), as well as two new lanostane triterpene acid ethyl esters, ethyl 3-O-acetylganoderate B (2) and Ethyl ganoderate J (5), were isolated and characterized from Ganoderma lucidum mycelia which was cultured by submerged fermentation method. Their structures were elucidated on the basis of spectroscopic methods. In addition, the identification of two known lanostane triterpene acid methyl esters, methyl O-acetyl ganoderate C and methyl 3,7,11,15,23-pentaoxo-lanost-8-en-26-oate were identified by comparison of the NMR data with those reported in the literature.
