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.

Isolation and identification of hemostatic ingredients from Lamiophlomis rotata (Benth.) Kudo[Pubmed:
19173219]
Lamiophlomis rotata (Benth.) Kudo (LR) is a traditional drug used by Chinese minorities such as Tibetans, Mongolians and Na Xi with the beneficial effects of hemostasis and alleviating pain. Flavonoids ingredients (P(1)), iridoid glycosides ingredients (P(2)) and maximus polarity components ingredients (P(3)) were isolated from the aqueous extract of LR (AELR) with polyamide and macroporous adsorptive resins chromatographic columns. The hemostatic activity of these ingredients was estimated by the changes in bleeding time (BT), clotting time (CT) and blood coagulation parameters in mice or rats. RP-HPLC was used to analyze the chemical composition of P(2). As a result, AELR and P(2) significantly shortened BT, CT and thrombin time (TT), and increased fibrinogen (FIB), but P(1) and P(3) showed no hemostatic effect during the experiment. Moreover, P(2) showed satisfactory hemostatic effect with dose-effect relationship and low toxicity in mice. 8-Dehydroxy shanzhiside, phloyoside II, shanzhiside methylester, loganin, and 8-O-acetylshanzhiside methylester were detected as the main iridoid glycosides in P(2) by RP-HPLC. Our results suggest that iridoid glycosides may be the hemostatic activity ingredients of L. rotata and are a potential hemostatic medicine.

[Iridoid glycosides from buds of Jasminum officinale L. var. grandiflorum][Pubmed:
22242454]
The study on the buds of Jasminum officinale L. var. grandiflorum was carried out to look for anti-HBV constituents. The isolation and purification were performed by HPLC and chromatography on silica gel, polyamide and Sephadex LH-20 column. The structures were elucidated on the basis of physicochemical properties and spectral analysis. Six iridoid glycosides were identified as jasgranoside B (1), 6-O-methy-catalpol (2), deacetyl asperulosidic acid (3), aucubin (4), 8-Dehydroxy shanzhiside (5), and loganin (6). Jasgranoside B (1) is a new compound. Compounds 2-6 were isolated from Jasminum officinale L. var. grandiflorum for the first time.
