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 structure determination of triglochinin, a new cyanogenic glucoside from Triglochin maritimum[Reference:
WebLink]
A new cyanogenic glucoside, triglochinin (O-[β-d-glucopyranosyl]-1-cyano-1-hydroxy-4,5-dicarboxy-1,3-pentadiene), was isolated from the flowers of Triglochin maritimum L. On hydrolysis, the glucoside decomposes (inter alia) to a new acid, Triglochinic acid (2-butene-1,2,4-tricarboxylic acid). The isolation and structure determination of the glucoside are described.

Study on the identification of Pinelliae rhizoma and Pinelliae pedatisectae rhizoma based on the characteristic component triglochinic acid[Pubmed:
35516978]
For the first time, a monomeric compound, Triglochinic acid, has been isolated from the tubers of Pinellia pedatisecta Schott with its structure analyzed using NMR. Its molecular formula is C7H8O6, with the chemical name (2E)-but-2-ene-1,2,4-tricarboxylic acid. Through HPLC-DAD and HPLC-MS analysis studies, it has concluded that Pinelliae rhizoma does not contain Triglochinic acid, while Pinelliae pedatisectae rhizoma does. This key observation was used as a characteristic component to distinguish these two herbs. We analyzed 39 batches of Pinelliae rhizoma collected in herbal medicine market, among which Triglochinic acid was detected in 27 batches, resulting in a adulteration ratio of Pinelliae rhizoma reaching 69.2%. Our method demonstrates great potential for authenticating the products, thus ensuring the quality of Pinelliae rhizoma.
