Meadowfoam seeds differ from the seed meal in that seeds, even after years of storage, contain active myrosinase whereas the meal does not. In order to prevent myrosinase-mediated degradation of glucohmnanthin during extraction, one could inactivate myrosinase by applying heat or by choosing a solvent in which myrosinase does not exhibit activity. We have found that heating seeds at temperatures... 

Fig. 10.8 Effect of fermentation on meadowfoam seed meal composition, in the absence (a) and presence of 10 mM FeS04 (b). Methods meadowfoam seed meal (12 g) and untreated meadowfoam seed (cv. Ross) were ground together in a ratio of 100 1 in a coffee grinder for 1 min. Ground mixture (10 g) was mixed with 30 mL of either water or 10 mM FeSOa, vortexed for 1 min, and sonicated for 1 min. At several time points after mixing, 0.1 mL ahquots of the liquid layer were taken and immediately diluted with 0.9 mL methanol, vortexed, centrifuged at 13,000 rpm for 10 min, and analyzed by HPLC as described in Fig. 10.7. Data points represent averages of duplicate incubations...

The coleoptile emergence assay was repeated with meadowfoam seed meal and fermented seed meals. The meal materials were mixed with soil at varying doses...

Olefin metathesis can be very useful in the CM mode, as shown in the synthesis of insect phere-mones.46 In the first example for the synthesis of the peach twig borer pheromone 23, an excess of 1-hexene was used to increase the yield of the desired product. However, both of the other products could be recycled (Scheme 28.17). In the second example, CM was used to change the ester groups of meadowfoam oil (24) through cleavage of the alkenes rather than ester bonds. The sequence resulted in the synthesis of the mosquito pheromone (25) (Scheme 28.18).
