D-calycanthine has antifungal activity, it shows significant inhibitory activities against five plant pathogenic fungi Exserohilum turcicum, Bipolaris maydis, Alternaria solani, Sclerotinia sderotiorum, and Fusarium oxysportium. Calycanthine is the principal alkaloid of the plant family Calycanthaceae. It is an aminal, an organonitrogen heterocyclic compound and a calycanthaceous alkaloid. It derives from a hydride of a calycanine.

Hastatoside is an iridoid monoterpenoid with formula C17H24O11 that is isolated from several plants including Verbena officinalis and exhibits a sleep-promoting effect. It has a role as a hepatoprotective agent and a plant metabolite. It is a beta-D-glucoside, a methyl ester, a cyclopentapyran, an iridoid monoterpenoid, an alpha,beta-unsaturated carboxylic ester, a monosaccharide derivative and a monoterpene glycoside. Hastatoside and verbenalin are major sleep-promoting components of V. officinalis. Hastatoside has anti-inflammatory activity.

Incensole has a protective or stimulating effect on β-cells of the rat pancreas, it also can increase the insulin secretion, which evidenced by a significant increase both in body weight and in liver glycogen.

Valerenic acid is a monocarboxylic acid that is 2-methylprop-2-enoic acid which is substituted at position 3 by a 3,7-dimethyl-2,4,5,6,7,7a-hexahydro-1H-inden-4-yl group. A bicyclic sesquiterpenoid constituent of the essential oil of the Valerian plant. It has a role as a volatile oil component, a sedative, a GABA modulator and a plant metabolite. It is a monocarboxylic acid, a sesquiterpenoid and a carbobicyclic compound. It is a conjugate acid of a valerenate. Valerenic acid, a subunit specific allosteric modulator of GABAA receptors, has anxiolytic, and antioxidant activities.

Pregnenolone is a 20-oxo steroid that is pregn-5-ene substituted by a beta-hydroxy group at position 3 and an oxo group at position 20. It has a role as a mouse metabolite and a human metabolite. It is a 3beta-hydroxy-Delta(5)-steroid, a 20-oxo steroid and a C21-steroid. It derives from a hydride of a pregnane. Pregnenolone is an endogenous steroid hormone for inhibition of M1 receptor and M3 receptor-mediated currents with IC50 of 11.4 μM and 6.0 μM, respectively. Pregnenolone has memory-enhancing effects, used in the treatment of fatigue, Alzheimer’s disease, trauma and injuries.

(±)-Borneol is a bornane monoterpenoid that is 1,7,7-trimethylbicyclo[2.2.1]heptane substituted by a hydroxy group at position 2. It has a role as a metabolite and a volatile oil component.(±)-Borneol is a bornane monoterpenoid that is 1,7,7-trimethylbicyclo[2.2.1]heptane substituted by a hydroxy group at position 2. It has a role as a metabolite and a volatile oil component. (±)-Borneol is a bicyclic monoterpene used for analgesia and anaesthesia in traditional Chinese and Japanese medicine, it and its enantiomer (±)-Borneol have a highly efficacious positive modulating action at GABA(A) receptors at human recombinant alpha1beta2gamma2L GABA(A) receptors. Borneol specifically inhibits the nicotinic acetylcholine receptor (nAChR)-mediated effects in a noncompetitive way, can depress P-glycoprotein function by a NF-κB signaling mediated mechanism in a blood brain barrier in vitro model. Borneol has neuroprotection through the inhibition of IκBα-NF-κB and translocation signaling pathway, it also has an anti-cerebral ischemia effects. It can suppresse inflammatory responses in LPS-induced acute lung injury through inhibition of the NF-κB and MAPKs signaling pathways.
