Juncus effusus Linn.

Effusol, a phenolic constituent from Juncus effuses, exhibits potent scavenging activity for DPPH and ABTS radicals, with IC₅₀ values of 79 μM and 2.73 μM, respectively. Effusol rescues CA1 LTP attenuated by corticosterone, defending the hippocampal function against stress-induced cognitive decline.

Dehydroeffusol is a phenanthrene from medicinal herb Juncus effuses. Dehydroeffusol inhibits gastric cancer cell growth and tumorigenicity by selectively inducing tumor-suppressive endoplasmic reticulum stress and a moderate apoptosis. It shows very low toxicity.

1-Methyleffusol is a natural phenolic compound.

1,6-Dimethyl-4,5-dihydropyrene-2,7-diol is a natural phenolic compound.

Effususol A is a natural phenolic compound.

9,10-Didehydroeffususol A is a natural phenolic compound.

Juncatrin B is a type of dihydrophenanthrene compound. Juncatrin B exhibits inhibitory activity against both Methicillin (HY-121544)-sensitive Staphylococcus aureus (MSSA) and Methicillin-resistant Staphylococcus aureus (MRSA). Juncatrin B can inhibit the formation of biofilms in MSSA and MRSA. Juncatrin B has no significant activity against Gram-negative bacteria. Juncatrin B can be used in the research of anti-Staphylococcus aureus.

2-Methoxy-1,6-dimethyl-5-vinyl-9,10-dihydrophenanthren-7-ol (Compound 1) is a 9,10-dihydrophenanthrene derivative. 2-Methoxy-1,6-dimethyl-5-vinyl-9,10-dihydrophenanthren-7-ol can be isolated from Juncus compressus. 2-Methoxy-1,6-dimethyl-5-vinyl-9,10-dihydrophenanthren-7-ol exhibits anticancer activity against cervical and ovarian cancers. 2-Methoxy-1,6-dimethyl-5-vinyl-9,10-dihydrophenanthren-7-ol can be used for HSV-2 virus research.
