Dictamnine, a natural product isolated and purified from the root barks of Dictamnus dasycarpus Turcz., has the ability to exert cytotoxicity in human cervix, colon, and oral carcinoma cells, and has antimicrobial activity against bacteria and fungi.

Fraxinellone, a natural product isolated and purified from the root barks of Dictamnus dasycarpus Turcz. with neuroprotective, vasorelaxing, insecticidal, and antimicrobial activities, is a selective blocker of voltage-dependent Ca2+ channel, while dictamine relaxed the rat aorta by suppressing the Ca2+ influx through both voltage-dependent and receptor-operated Ca2+ channels, and can dramatically induce apoptosis of activated peripheral CD4(+) T cells in vivo, consequently resulting in less CD4(+) T-cell activation and infiltration to the liver.

Isomaculosidine, a natural product isolated and purified from root barks of Dictamnus dasycarpus, can significantly inhibit nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated BV2 cells.

Dasycarpol is a natural product isolated and purified from the root barks of Dictamnus dasycarpus, with moderate inhibitory activity on lung cancer cell line A549 and significant neuroprotective activity against glutamate-induced neurotoxicity in primary cultures of rat cortical cells at a concentration of 0.1 mM.

Ravenine is a natural product isolated and purified from Ammi visnaga (L.) Lam..

Isopteleine, a natural product isolated and purified from the roots of Dictamnus angustifolius, shows weak cytotoxic activities against human breast cancer cells (MCF7), and is a quinoline alkaloid from the roots of Dictamnus angustifolius.

Preskimmianine, a natural product isolated and purified from the root barks of Dictamnus dasycarpus. and a biogenetic precursor of skimmianine, can significantly inhibit nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated BV2 cells.

Isodictamnine is a natural product isolated and purified from plants.
