In Vitro
During a screening program for new agrochemicals from Chinese medicinal herbs, the ethanol extract of Notopterygium incisum rhizomes is found to possess strong nematicidal activity against the two species of nematodes, Bursaphelenchus xylophilus and Meloidogyne incognita. Based on bioactivity-guided fractionation, the four constituents are isolated from the ethanol extract and identified as Columbianetin, Falcarindiol, Falcarinol, and Isoimperatorin. Isoimperatorin also has LC50 values of 21.83 μg/mL against B. xylophilus. When using 15 min UV light treatment, falcarindiol, falcarinol, and isoimperatorin demonstrated almost five times more toxic to the southern root-knot nematodes than in dark treatment while columbianetin showed only two times more toxic. isoimperatorin has been demonstrated to possess insecticidal activity against several insects, such as the cabbage aphid (Brevicoryne brassicae)[2]. Isoimperatorin is identified in the active fraction of Angelica dahurica (AD) extract[3]. Isoimperatorin is usually used as the internal standard (IS)[4].

Solvant et solubilité
In Vitro:
Ethanol : 6.25 mg/mL (23.12 mM; Need ultrasonic)
DMSO : 2.5 mg/mL (9.25 mM; ultrasonic and warming and heat to 60°C; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (protect from light). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

In Vivo:
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% EtOH 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 0.62 mg/mL (2.29 mM); Clear solution
This protocol yields a clear solution of ≥ 0.62 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL EtOH stock solution (6.2 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
For the following dissolution methods, please prepare the working solution directly:
It is recommended to prepare fresh solutions and use them promptly within a short period of time.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
