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.

Chemical Constituents of the Fungus Leccinum extremiorientale[Reference: WebLink]

METHODS AND RESULTS:
Thirteen chemical constituents were isolated from the fruiting bodies of basidiomyctes Leccinum extremiorientale, and their structures were elucidated by spectral and physical-chemical data as: ergosta-7,22-dien-3β,5α,6β-triol (1), ergosterol peroxide (2), ergosterol (3), ergosta-4,6,8(14),22-tetraen-3-one (4), ergosta-5,7-dien-3β-ol (5), palmitic acid (6), (2S,3S,4R,2′R)-2-2'-(Hydroxytetracosanoylamino)-octadecane-1,3,4-triol (7), cerebroside B (8), cerebroside D (9), uracil (10), inosine (11), adeosine (12) and D-allitol (13). The NMR data of compounds 8 and 9 were completely assigned by 2D-NMR techniques, including 1H-1H COSY, HMBC and HMQC.
CONCLUSIONS:
Compounds 2, 7 and 8 at concentration of 100 μg/mL showed selectively inhibitory activity against phospholipase A 2 (PLA 2) secreted from Crotalus adamenteus venom, but inactive against PLA 2 of bee venom (Apis mellifcra). In addition, the methanol-chloroform soluble extract of this fungus also showed 67% antifeedant rate against Leucaninia separata and caused 55% mortality against Plutella xylostella after three-day application.
