Description

Petroleum-ether extract of pyrethrum flowers concentrated to the commercial concentration is a brown liquid containing about 20% of pyrethrin. When it is allowed to stand for about one week, wax-like precipitate is formed as semi-solid masses at the bottom of the container. From the unsaponifiable matter, which were obtained from the above-mentioned wax-like precpitate, the author could isolate several substances such as β-amyrenol (β-amyrin), ceryl alcohol, hentriacontane, nonacosane or octacosane, and other substances.
