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.

Labdane-type diterpenes active against acne from pine cones (Pinus densiflora).[Pubmed: 18484541]

METHODS AND RESULTS:
Bioassay-guided extraction and fractionation of the aqueous methanolic extract of the cones of Pinus densiflora (Pinaceae) afforded one new labdane-type diterpene aldehyde, 15-nor-14-oxolabda-8(17),12 E-diene-18-oic acid(15-Nor-14-oxolabda-8(17),12-dien-18-oic acid ), along with eight known diterpenes. Their structures were elucidated using spectroscopic methods as well as by comparison with previously reported data.
CONCLUSIONS:
The isolates showed antibacterial (Propionibacterium acnes) and antifungal activities.
