Indole-3-acetic acid is a monocarboxylic acid that is acetic acid in which one of the methyl hydrogens has been replaced by a 1H-indol-3-yl group. It has a role as an auxin, a plant hormone, a mouse metabolite, a plant metabolite and a human metabolite. It is a member of indole-3-acetic acids and a monocarboxylic acid. It is a conjugate acid of an indole-3-acetate. Indole-3-acetic acid , a well-known phytohormone, can also be a signaling molecule in bacteria and therefore can have a direct effect on bacterial physiology.

Albiflorin is a monoterpene glycoside with formula C23H28O11, originally isolated from the roots of Paeonia lactiflora. It has a role as a neuroprotective agent and a plant metabolite. It is a beta-D-glucoside, a secondary alcohol, a bridged compound, a benzoate ester, a gamma-lactone and a monoterpene glycoside. Albiflorin has anti-inflammatory, and antidepressant-like effects. Albiflorin may reduce or prevent osteoblast degeneration in osteoporosis, and may promote the recovery of bone marrow hemopoietic function in a myelosuppressed mouse model, it has neuroprotective effect on primary hippocampal cells against β-amyloid induced toxicity. Albiflorin is a monoterpene glycoside with neuroprotective effects that can cross the blood-brain barrier. It also exhibits anti-inflammatory, antioxidant, and analgesic properties.
