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.
Need more advice on solubility, usage and handling? Please email to: email@example.com
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.

Antiviral Terpenoid Constituents of Ganoderma pfeifferi.[Pubmed: 16378363
METHODS AND RESULTS:
Four sterols and 10 triterpenes were isolated from the fruiting bodies of Ganoderma pfeifferi, including the three new triterpenes 3,7,11-trioxo-5alpha-lanosta-8,24-diene-26-al (lucialdehyde D, 1), 5alpha-lanosta-8,24-diene-26-hydroxy-3,7-dione (ganoderone A, 2), and 5alpha-lanosta-8-ene-24,25-epoxy-26-hydroxy-3,7-dione (ganoderone C, 3). The structures of 1-3 were determined on the basis of spectroscopic evidence. Antibacterial, antifungal, and antiviral activity were studied for some of the isolated compounds.
Ganoderone A (2), Lucialdehyde B (4), and ergosta-7,22-dien-3beta-ol (7) were found to exhibit potent inhibitory activity against herpes simplex virus.

New triterpene aldehydes, lucialdehydes A-C, from Ganoderma lucidum and their cytotoxicity against murine and human tumor cells.[Pubmed: 12045343
Three new lanostante-type triterpene aldehydes, named lucialdehydes A-C (1-3), were isolated from the fruiting bodies of Ganoderma lucidum, together with ganodermanonol (4), ganodermadiol (5), ganodermanondiol (6), ganodermanontriol (7), ganoderic acid A (8), ganoderic acid B8 (9), and ganoderic acid C1 (10).
METHODS AND RESULTS:
The structures of the new triterpenes were determined as (24E)-3 beta-hydroxy-5 alpha-lanosta-7,9(11),24-trien-26-al (1), (24E)-3,7-dioxo-5 alpha-lanosta-8,24-dien-26-al (2), and (24E)-3 beta-hydroxy-7-oxo-5 alpha-lanosta-8,24-dien-26-al (3), respectively, by spectroscopic means. The cytotoxicity of the compounds isolated from the ganoderma mushroom was tested in vitro against Lewis lung carcinoma (LLC), T-47D, Sarcoma 180, and Meth-A tumor cell lines. Lucialdehyde B, Lucialdehyde C (2, 3), ganodermanonol (4) and ganodermanondiol (6) showed cytotoxic effects on tested tumor cells.
Of the compounds, lucialdehyde C (3) exhibited the most potent cytotoxicity against LLC, T-47D, Sarcoma 180, and Meth-A tumor cells with ED(50) values of 10.7, 4.7, 7.1, and 3.8 microg/ml, respectively.
