Description

Alkaloidal Compound Matrine.

(Note: all prices are listed in CAD.)

Matrine is an alkaloidal compound which occurs naturally in the plant Sophora flavescens. It is a known antifeedant against the formosan subterranean termite, with an average LD50 of 8.3 micrograms (of matrine hydrochloride) per insect [1]. Entomological studies have shown that it also prevents wood damage in the common types used in furniture and housing. In one study researches observed full protection against termite damage after applying a coating of 5% matrine hydrochloride in water (by weight, e.g. 50 grams matrine hydrochloride per kilogram) on wood [1]. It also has nematicidal effects against the pine wood nematode, which causes the blight known as pine wilt on pine wood [2].

This compound is available as the hydrochloride salt. It is NOT intended for human consumption, and is for laboratory reagent or forensic/analytical purposes ONLY. The intent of its sale is agrochemical and other agricultural research.
