Ginsenoside Rb3 is a protopanaxadiol ginsenoside that can be isolated from several different Panax species. Ginsenoside Rb3 exerts antidepressant and antidiabetic activities as well as cardio- and neroprotective action in ischemic tissue injury in animal models. Ginsenoside Rb3 inhibits apoptosis and cell proliferation, in addition it demonstrates antiaxidant properties. Ginsenoside Rb3 may modulate activity of GABA-A and NMDA receptors.

Methyl chlorogenate, an antioxidant flavonoid, exhibited strong activity against HDAC8 and the high affinity to trichostatin A binding site. Methyl chlorogenate showed specific cytotoxicity against certain types of tested cancer cell lines such as Hep2 and MCF7. Methyl chlorogenate may inhibit NFkappaB activation, exhibiting its ability to downregulate the NFkappaB-dependent gene expression. Thus, it can be expected that Methyl chlorogenate may have potential for therapeutic intervention on various NFkappaB-dependent pathological conditions such as inflammatory or possibly mutagenic processes. Methyl chlorogenate has demonstrated antioxidant activity.

Desacetoxymatricarin is a sesquiterpene lactone found in the genus Artemisia and in the form of 8-hydroxy and acetoxy derivatives in the genus Achillea. The formation of desacetoxymatricarin from (+)-costunolide probably involves more than one enzyme, including a cytochrome P450 enzyme. It is a potent 3-hydroxy-3-methylglutaryl-CoA reductase (HMGR) inhibitor. Desacetoxymatricarin showed the highest anti-hypercholesterolemic potential. Oligvon, a preparation containing desacetoxymatricarin, is used to prevent and treat artherosclerosis.

Isovitexin (apigenin-6-C-glucoside), an isomer of vitexin, is found in plants such as pigeon pea, Passiflora, bamboo, mimosa, wheat leaves, rice hull of Oryza sativa and others. Isovitexin is poorly absorbed in the gastrointestinal tract. The highest level of intravenously administrated isovitexin was examined in kidney, liver, lung, and lowest in the brain. Isovitexin helps to stimulate apoptotic cell death and autophagy of various cancer cells through the upstream regulation of Bax, PARP, p-JNK, and MAPK and the downstream regulation of the caspases Bcl-2 and ERK1/2. Isovitexin has been proved to have various activities, such as anti-oxidant, anti-inflammatory, anti-Alzheimer's disease and others.

Quebrachitol (QCT), a bioactive plant constituent, is a naturally occurring optically active cyclitols. QCT could serve as the starting material of inositol or its derivatives to participate in several important pathways and may act as a potential anticancer or antidiabetic drug lead to arrest or reverse these diseases. According to the literature reported before, QCT exerted its biological functions, by involving IP3 receptor, b-glucosidase, PAFR, COX2, nitric oxide synthase, and K(+)ATP channels. Quebrachitol reduces the gastric damage induced by ethanol and indomethacin. The potential of quebrachitol as a sugar substitute for diabetics has been investigated. Even though the early study reported that this methylcyclitol seems neither to prevent hypoglycemia nor to raise blood sugar content, another work showed that quebrachitol has hypoglycemic effects in hyperglycemic rats. Unfortunately, all three persons who took quebrachitol by mouth had fairly severe diarrhea.

Cortex fraxini, a famous Chinese herbal folk medicine, is used for the clinical treatment of hyperuricemia, arthritis, diarrhea, liver-protective. and bacillary dysentery. Fraxin, a main active component isolated from Cortex fraxini, possesses a variety of bioactivities such as anti-inflammatory, antioxidant, analgesic, antimicrobial, antiviral, immunomodulatory, anti-hyperuricemia and diuresis. And a recent study indicated that fraxin showed potent hepatoprotective effects in vitro and in vivo, presumably through reducing Oxidative Stress. Fraxin protects cells from oxidative stress.
