What it is Filled
A group of natural compounds built on a 1,2-diphenylethane (bibenzyl) skeleton, commonly hydroxylated or methoxylated; the saturated counterparts of stilbenoids, found mainly in plants such as orchids and yams and in liverworts.
Why it exists Filled
Let an agent classify a compound as a dihydrostilbenoid, name its sources and reported activities, and find chemical database records, without health claims.
Distinguishing features Filled
- The two benzene rings are linked by a saturated -CH2-CH2- bridge; stilbenoids have a double bond there.
- Also called bibenzyls.
- Related dihydrophenanthrenes are formed by ring closure.
What robots and AI may and may not do Filled
Must not
- make therapeutic claims
- give doses of extracts
May
- classify compounds and summarise research
Moral aspects Filled
- honesty about preliminary research
- sustainable harvesting of wild orchids
Who is affected
- consumers of herbal products
- wild plant populations
Owners Filled
