High impact information on Asclepias

• Gomphoside, a 5 alpha-H cardiac glycoside isolated from Asclepias fructicosa, has an unique double glycosidic linkage to the aglycon through oxygen atoms at 2 alpha and 3 beta of the steroid [1].
• A cDNA for a structurally variant acyl-acyl carrier protein (ACP) desaturase was isolated from milkweed (Asclepias syriaca) seed, a tissue enriched in palmitoleic (16:1delta9)* and cis-vaccenic (18:1delta11) acids [2].
• Among the major cardenolides from the milkweed Asclepias asperula, 6'-O-(E-4-hydroxycinnamoyl) desglucouzarin has not been characterized biochemically [3].
• Seasonal development of ozone-induced foliar injury on tall milkweed (Asclepias exaltata) in Great Smoky Mountains National Park [4].
• Density effects of the aposematic oleander aphid, Aphis nerii, on cardenolide expression were measured in two milkweed species, Asclepias curassavica and A. incarnata [5].

Biological context of Asclepias

• Oviposition stimulants for the monarch butterfly: flavonol glycosides from Asclepias curassavica [6].

Associations of Asclepias with chemical compounds

• Steroidal glycosides and cardenolide glycosides from Asclepias fruticosa [7].
• Asclepias speciosa Torr. has latex-containing cells known as nonarticulated laticifers [8].
• The aerial part of Asclepias incarnata afforded 34 pregnane glycosides [9].
• Effects on sheep of the milkweeds Asclepias eriocarpa and A. labriformis and of cardiac glycoside-containing derivative material [10].
• An androstane bioside and 3'-thiazolidinone derivatives of doubly-linked cardenolide glycosides from the roots of Asclepias tuberosa [11].
