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.

Fragrant volatile sesquiterpenoids isolated from the essential oil of Laggera pterodonta by using olfactory-guided fractionation.[Pubmed:
25238080 ]
METHODS AND RESULTS:
Chemical composition of the essential oil from Laggera pterodonta (Compositae) was inverstigated. GC/MS Analyses led to the identification of 68 components, representing more than 96% of the total oil. By focusing on the woody note fraction of the essential oil, one new bisabolane-type sesquiterpenoid, bisabola-2,7(14),11-trien-10-ol (1), together with ten known compounds, bisabolol oxide B (2), Ylangenol (3), copaborneol (4), guai-11-en-10-ol (5), spathulenol (6), aromadendran-10-ol (7), caryophyllenol (8), 5α,7α-eudesm-11(13)-en-4α-ol (9), γ-costic acid (10), and eudesma-4(15),11(13)-diene-12,5β-olide (11), were isolated by using olfactory-guided fractionation. The structures of the eleven compounds were determined by NMR and MS analyses.
CONCLUSIONS:
All the volatile compounds reported here were isolated for the first time from this plant. On the basis of preliminary odor assessment, the odor of the woody-note fractions of the essential oil was assumed to be due to these isolated sesquiterpenoids.
