Asclepias syriaca

In contrast to corresponding flavones, only a few structures are reported with a pyrano-substitution, mostly of the chromeno-type between the 7-OH and the neighboring C-8. Major sources are roots, aerial parts, and leaves from Rutaceae, Moraceae, and Fabaceae. The earlier reported Asclepias syriaca (Asclepiadaceae) affords a rare source of such structures. So far, the corresponding 7,6-chromeno structures (sarothranol) are known only from whole plants of Hypericum japonicum (Hypericaceae). ... [Pg.709]

Although this family is pantropical, most of its members are South American. A few genera extend into temperate regions one of these is Lhc familiar milkweed, Asclepias syriaca. Some are ornamentals, some yield rubber, others are livestock poisons. The taxonomy of the family is not a matter of general agreement. [Pg.24]

Acyl-ACP Desaturation. The first step in cts-vaccenate biosynthesis is desaturation of pabnitoyl-ACP to palmi-toleoyl-ACP. Cahoon et al. (10) have cloned the gene for acyl-ACP desaturase from Asclepias syriaca and demonstrated that it had mixed specificity, i.e., it could effectively desaturate palmitoyl-ACP and stearoyl-ACP. This is in contrast to normal oilseeds (which do not produce c -vacce-nate) such as safflower in which the acyl-ACP desaturase is highly specific for stearoyl-ACP (9). [Pg.60]
