„The flower buds are used in Southern Chinese cuisine, Vietnamese cuisine and Northern Thai cuisine, where they are stir-fried or boiled in broth.“
Essential oil (simultaneous distillation and extraction, SDE) of Telosma cordata flowers growing in Hawaii contained a total of 43 compounds (GC-MS). Geraniol, β-ionone, dihydro-β-ionone, dihydro-β-ionol, and cis- and trans-theaspirane were found to make a major contribution to the characteristic rose-like scent of the flowers.
