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: service@chemfaces.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.

Nortriterpenoids and lignans from the fruit of Schisandra chinensis.[Pubmed:
21139263]
METHODS AND RESULTS:
Phytochemical investigation of the fruit of Schisandra chinensis led to the isolation of a schisanartane nortriterpenoid, schindilactone H (1); an 18-norschiartane bisnortriterpenoid, wuweizidilactone I (2); two tetrahydrofuran-type lignans, schinlignins A and B (18 and 19); and three dibenzyl butane-type lignans, schineolignin A，Schineolignin B,schineolignin C (20-22), together with 16 known compounds. The structures of these new compounds were elucidated on the basis of extensive analysis of spectroscopic data.

Lignoids Isolated from Nectandra turbacensis (Kunth) Nees (Lauraceae)[Reference:
WebLink]
METHODS AND RESULTS:
A new 7,8-secolignan, as well as seven known compounds; were isolated from Nectandra turbacensis (Kunth) Nees (Lauraceae) (leaves and root bark). These compounds were identified as, one secolignan, turbacenlignan A (1); four diaryldimethylbutane lignans: meso-monomethyl dihydroguaiaretic acid (2), threo-dihydroguaiaretic acid (3), Schineolignin B (4), and austrobailignan-5 (5); and three 7,7'-epoxylignans: henricine (6) and the identifiable mixture of veraguensin (7) and galgravin (8).
CONCLUSIONS:
Compounds 1-8, were first isolated from Nectandra turbacensis (Kunth) Nees (Lauraceae) (leaves and root bark) and compounds 1, 6-8, were isolated for the first time from Nectandra genus.
