The enzyme 1,2-dihydroxy-6-methylcyclohexa-3,5-dienecarboxylate dehydrogenase uses 1,2-dihydroxy-6-methylcyclohexa-3,5-dienecarboxylate and NAD+ to produce 3-methylcatechol, NADH and CO2.
The enzyme 3,7-dimethylquercetin 4'-O-methyltransferase uses S-adenosyl methionine and 5,3',4'-trihydroxy-3,7-dimethoxyflavone (rhamnazin) to produce S-adenosylhomocysteine and 5,3'-dihydroxy-3,7,4'-trimethoxyflavone (ayanin).
Dihydrochalcones (3′,5′-dihydroxy-2′,4′,6′-trimethoxydihydrochalcone, methyl linderone, 5-hydroxy-6,7,8-trimethoxyflavone (alnetin) and 2′-hydroxy-3′,4′,5′,6′-tetramethoxydihydrochalcone (dihydrokanakugiol) can be found in twigs of Lindera lucida.
The anthraquinone aldehyde nordamnacanthal (1,3-dihydroxy-anthraquinone-2-al) present in G. aparine has an antifeedant activity against Spodoptera litura, the Oriental leafworm moth, a species which is considered an agricultural pest.
Androstanediol (3β,17β-dihydroxy-5α-androstane and 3α,17β-dihydroxy-5α-androstane)
