Chinese tallow tree Sapium

A number of closely related linear allenes have also been isolated from seed oils (Scheme 18.8). Examples are laballenic acid (18) [27], lamenallenic acid (19) [28] and phlomic acid (20) [29]. The hydroxy acid 21 was isolated as part of a triglyceride from the Chinese tallow tree Sapium sebiferum [30] and as its methyl ester 22 from the related species Sapium japonicum [31], which is found in Japan.

With the aid of adsorption TLC, it has been discovered that the seed oil of the Chinese tallow tree (Sapium sebiferum) contains up to about 25% of a fraction only a little more polar than normal triglycerides. These compounds have been characterised as mono-estolide triglycerides, i. e. (mono)hydroxy-triglycerides, esterified with ordinary fatty acids [192]. The following types of estolide-triglyceride have been...
