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.

Dammarane triterpenoid saponins from Bacopa monnieri.[Reference:
WebLink]
Bacopa monnieri is a well-known Ayurvedic Indian medicinal plant traditionally used as a memory enhancer. Its memory-enhancing effect is mainly attributed to dammarane triterpenoid saponins.
METHODS AND RESULTS:
In the present study, two new dammarane-type triterpenoid saponins, bacopaside-XI (1) and bacopaside-XII (2), together with known compounds, Bacopaside IV, bacopaside V, and apigenin, were isolated from the aerial parts of the B. monnieri. The structures of the new saponins were elucidated as 3-O-[α-L-arabinofuranosyl(1→3)]-6-O-sulfonyl-β-D-glucopyranosyl pseudojujubogenin (1) and 3-O-{β-D-glucopyranosyl(1→3)[α-L-arabinofuranosyl(1→2)]-β-D-glucopyranosyl}-20-O-α-L-arabinopyranosyl pseudojujubogenin (2) on the basis of extensive investigations of 1D and 2D NMR (HMQC and HMBC), ESI-QTOF-MS/MS spectroscopic methods, and chemical evidences.
