Active Phytochemicals

1. Saponins
Multiple species of Cestrum have been shown to have steroidal saponins. The presence of gitogenin and digitogenin in fresh green berries of C. parqui was achnowledged. Toxicity in grazing animals is due to kaurene glycoside in leaves. Anti-inflammatory characteristic is present in parquisosides. Several species possess various other steroidal saponins such as furostanol saponins, flavonoidal saponins, etc.

2. Alkaloids- parquine, 1-carbamoyl pyrrolidin-2-one, cotinine, solanodine
3. Volatile oils
4. Terpenes
5. Lignans- liriodendrin, (+) – syringaresinol, (-) – simulanol

6. Phenolic compounds – syringic acid, caffeic acid, methyl ferulate
7. Flavones and flavonoids- 4’-hydroxy-4-methoxy chalcone, quercetin
