A Korean called Gymnaster koraiensis yeilds a polyacetylene in its yellow oil extract which has been observed to:
"exhibit potent cytotoxic, antimicrobial, antiviral , RNA-cleaving, sedative, .and enzyme-inhibitory activities, as well as brine-shrimp lethality.*
Note Well: from 'local folklore': harebell remedies must be micro-picked for seed potential if used for eye drops, so make your own only if you have the equipment. From Dermatology study: Campanulae cause some contact dermatitis.
Polyacetylenes have been found in many families of higher plants, such as the Araliaceae, Campanulaceae, Compositae, Olacaceae, Pottosporaceae, Santalaceae, and Umbelliferae.1-4
More recently, linear polyacetylenes have become a major element in the search for bioactive substances from marine sponges.5-7
It has been reported that these compounds exhibit potent cytotoxic, antimicrobial, antiviral, RNA-cleaving, sedative, and enzyme-inhibitory activities, as well as brine-shrimp lethality.
8-14 Gymnaster koraiensis (Nakai) Kitamura (Compositae) is an endemic species in Korea, but its constituents and biological activities have not been investigated previously.
