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.

Study on 6 insecticidal podophyllotoxin compounds from the berries of Sabina vulgaris Ant.[Reference:
WebLink]
METHODS AND RESULTS:
In order to isolate other insecticidal podophyllotoxin compounds from the berries of Sabina vulgaris Ant.,six podophyllotoxin compounds were isolated by tracing with insecticidal activity.
They were identified as acetyl picropodophyllotoxin,deoxypicropodophyllotoxin,
Acetylepipodophyllotoxin,podophyllotoxin,deoxypodophyllotoxin and picropodophyllotoxin.The antifeeding activities against the 3rd-instar larve of Mythimna separate W.and the toxic activities against the 4th-instar larvae of Pieris rapae L.and the 3rd-instar larve of Plutella xylostella L.were tested by leaf-disk method and leaf-dipping method,respectively.
CONCLUSIONS:
The bioassay results indicated that all these compounds showed highly antifeeding and toxic activities against the 3 tested insects.Podophyllotoxin and deoxypodophyllotoxin were the two with the highest insecticidal activities among the six,while picropodophyllotoxin was the lowest.Besides,acetyl picropodophyllotoxin,deoxypicropodophyllotoxin,Acetylepipodophyllotoxin and picropodophyllotoxin were insecticidal compounds firstly reported from S.vulgaris.
