Osthole

What is Osthole?

Osthole is a substance extracted from the fruit of the annual Umbelliferae plant Fructus Cnidii. It appears as yellow-green to white crystalline powder. It is insoluble in cold water and petroleum ether, easily soluble in acetone, methanol, ethanol, chloroform and ethyl acetate and soluble in boiling petroleum ether. It has various effects including antispasmodic, hypotensive, anti-arrhythmic, enhancing immune function and broad-spectrum antimicrobial effect. It is clinically mainly used for the treatment of men impotence, scrotal wet itchy, women prurUus Yulvae and cold uterus and infertility, rheumatism, scabies, eczema and trichomonas vaginitis.

Osthole, as a kind of botanical pesticide, has contact-killing effect being the primary effect and stomach poisoning effect being the auxiliary effect. The drug liquid can be absorbed into the insect body through body surface and acts on the nervous system of pests, causing non-functional muscle contraction and final death due to energy exhaustion. Indoor activity virulence tests have showed that it has a higher activity against Pieris rapae (LD50 is 6.2258 mg/kg). It is demonstrated through the field efficacy trials that it has excellent efficacy in the treatment of Pieris rapae of cruciferous vegetables and tea and tea looper caterpillar. The drug dosage for prevention and treatment of the Pieris rapae of cruciferous vegetables has the active ingredient be 4.8~7.2g/hm (equals to 80~120 mL per acre if converted to 0.4%

Osthole Applications:

The application of botanical pesticides is a good choice in organic agriculture. However, most botanical pesticides have limitations of slow action and short persistence for pest and disease management, which constrain their further application. With the objective of exploring a green pesticide for controlling strawberry pests and diseases simultaneously, a star polymer (SPc) with a low production cost was synthesized as a pesticide nanocarrier through simple reactions. The SPc complexed with osthole quickly through electrostatic interaction and hydrophobic association, which decreased the particle size of osthole down to the nanoscale (17.66 nm). With the help of SPc, more nano-sized osthole was delivered into cytoplasm through endocytosis, leading to the enhanced cytotoxicity against insect cells.

As a green botanical pesticide, the control efficacy of the osthole/SPc complex was improved against main strawberry pests (green peach aphid and two-spotted spider mite) and disease (powdery mildew), which fulfilled the need of both pest and disease management in sustainable production of strawberry. Meanwhile, the introduction of SPc not only improved plant-uptake but also decreased the residue of osthole due to the higher degradation rate. Furthermore, the application of the osthole/SPc complex exhibited no influence on the strawberry fruit quality and nontarget predators. To our knowledge, it is the first success to control plant pests and diseases simultaneously for sustainable agriculture by only one pesticidal formulation based on nanoparticle-delivered botanical pesticides.The application of botanical pesticides is a good choice in organic agriculture.
