Kampo

Tetradium ruticarpum is called 呉茱萸 (Goshuyu) in Japanese, used in Goshuyu-tou and Unkentou (ja:温経湯). These are Kampo (漢方) preparations of mixed herbs, the former named after this plant.[2] The mixture is noted for having a high concentration (132.6 to 706.3 mmol/100 g) of antioxidants, where the other constituents of the mixture rank lower.[3]

Contraindications

Allergic reactions have occasionally been reported in users of medicinal preparations of the plant.[citation needed]

Biochemical analysis

There has been relatively little scientific study of Tetradium ruticarpum except for antioxidant capacity of one of its mixtures.

Notable compounds in T. ruticarpum include:[4]

alkaloids
:

  • COX-2 inhibitor
  • 0-hydroxyrutaecarpine
  • evodiamine, a possible thermogenic agent and stimulant, named after the former name of the genus
  • dehydroevodiamine
  • synephrine, an adrenergic receptor agonist
  • 1-methyl-2-n-nonyl-4(1H)quinolone
  • evocarpine
  • dihydroevocarpine

flavonoids
:

In rats, the half-lives of most of these compounds was found to be relatively short, between 0.5 - 2 hours.[4]

Variants

There are a few variants:[5]

  • var. officinalis
  • var bodinieri (Dode) Huang
