6-Gingerol Ginger-Rhizomes6-Shogaol is isolated from the dried or cooked rhizomes or roots of the plant Zingiber officinale (ginger). It is a perennial reed-like plant with annual leafy stems, about a meter (3 to 4 feet) tall. 6-Shogaol is a dehydrated 6-gingerol molecule that has lost a molecule of water during the drying or cooking process.

Ginger produces clusters of white and pink flower buds that bloom into yellow flowers. Because of its aesthetic appeal and the adaptation of the plant to warm climates, ginger is often used as landscaping around subtropical homes. Traditionally, the root is gathered when the stalk withers; it is immediately dried, scalded, or washed and scraped, to kill it and prevent sprouting.

6-Shogaol is isolated from dried or cooked ginger root using ethanol and other organic solvents followed by chromatographic purification. Aphios isolates 6-shogaol utilizing near-critical and supercritical fluids using CXF and CXP enabling technology platforms as alternatives to ethanol and conventional organic solvents techniques.

Biological Activity:

Ginger (Zingiber officinale Roscoe, Zingiberaceae) is a medicinal plant that has been widely used in Chinese, Ayurvedic and other global herbal medicinal practices since ancient times for a wide array of ailments including arthritis, rheumatism, sprains, muscular aches, pains, sore throats, cramps, constipation, indigestion, vomiting, hypertension, dementia, fever, infectious diseases and helminthiasis (Ali et al., 2008).

Ginger has been approved for use by Germany's Commission E, the agency responsible for regulating the use of herbal products in that country (Blumenthal, 1998). Ginger has recently been studied scientifically for its effect on nausea and vomiting associated with motion sickness, surgery, pregnancy and cancer chemotherapy.

There may be several mechanisms of action in play relative to the antiemetic properties of ginger. It has been reported that the antiemetic qualities may be derived from ginger's anti-serotonin 3 effects on the gastrointestinal and central nervous system (Chaiyakunapruk et al., 2006). In a study of guinea pig ileum, it was found that certain ingredients of ginger (6-, 8- and 10-gingerols) inhibit the anti-serotonin 3 receptor function (Huang et al., 1991 and Yamahara et al., 1989). In addition, these active ingredients have been shown to affect gastric motility and potentially have an antispasmodic effect on the gastrointestinal system (Hashimoto et al., 2002 and Suekawa et al., 1984).

Pan et al. (2008) investigated the inhibitory effects of 6-shogaol and a related compound, 6-gingerol, on the induction of nitric oxide synthase (NOS) and cyclooxygenase-2 (COX-2) in murine RAW 264.7 cells activated with LPS. Their results show that 6-shogaol downregulates inflammatory iNOS and COX-2 gene expression in macrophages by inhibiting the activation of NF-κB by interfering with the activation PI3K/Akt/I κB kinases IKK and MAPK.
