Juniperus communis L.

Oleuropeic acid 8-O-glucoside is a terpenic compound, that can be isolated from twigs with leaves of Juniperus communis var. depressa. Oleuropeic acid 8-O-glucoside shows antibacterial activity against three strains of Helicobacter pylori (NCTC11637, NCTC11916, and OCO1), with MIC of 100 μg/mL all.

Junipercomnoside A is a neolignan glycoside that can be isolated from the aerial parts of Juniperus communis var. depressa.

6,7-Dehydroferruginol is a diterpenoid compound that can be isolated from the dichloromethane extract of Juniperus communis wood. At a concentration of 100 μg/mL, 6,7-Dehydroferruginol showed no inhibitory activity against 12(S)-LOX and did not inhibit the production of 12(S)-HETE.

Sabinene hydrate is a volatile organic compound of a bicyclic monoterpene alcohol. Sabinene hydrate, as a plant secondary metabolite, is naturally present in various plants and their essential oils. Sabinene hydrate exhibits broad-spectrum but varying-intensity antibacterial activity, with the greatest sensitivity to Gram-positive bacteria, especially Bacillus subtilis (MIC = 0.0312 mg/mL) and Staphylococcus aureus (MIC = 0.0625 mg/mL). Sabinene hydrate also shows certain sensitivity to Escherichia coli and Candida albicans, with MIC values of 0.125 mg/mL for both. Sabinene hydrate can be used in the research of the ecological functions of plant defense substances.

12E,14-Trien-19-oic acid is a diterpenoid. 12E,14-Trien-19-oic acid can be isolated from Bhutanese medicinal plant, shug chher. 12E,14-Trien-19-oic acid can be used for the research of platelet aggregation.
