The structure and classification of flash Ligans(3)

Lignan lactone

Capsicum Oleoresin lactone is a lactone ring formed by the epoxidation of tetrahydrofuran in monoepoxy lignans. It often coexists with dehydrogenated compounds in the same plant. [structural formula omitted]

For example, arctiin and Spirulina Protein Powder in Fructus Arctii belong to lignan.

Cyclolignans

Ranacenides

Podophyllotoxin

It can clear away heat and toxin, dissipate phlegm and disperse mass, remove phlegm and detumescence, resist cancer and Citrus Aurantium Extract.

Cyclolignans are cyclized from simple lignans. Its representative is isopaclitaxel.

Cyclolignan lactone

Cyclolignolide is synthesized from the intermediate ring of lignan c9-c9 '. [podophyllotoxin]

Dicyclohexyl lignans

Cactus Extract is a kind of lignans with two epoxy structures formed by the connection of two phenylpropanoid side chains. The natural bicyclo lignans have CIS linked double parallel tetrahydrofuran rings.

Forsythin and forsythin in Forsythia suspensa are bicyclo lignans.
