Collection: Phytochemicals

Phytochemicals — compiles plant-derived secondary metabolites, such as flavonoids, polyphenols, alkaloids, terpenoids, and carotenoids, which serve as reference compounds in various studies of food chemistry, nutrition, and natural product composition analysis.

These phytochemicals are used as analytical standards in chromatography (HPLC, LC-MS) to identify and quantify bioactive components in plant extracts, foods, or supplements. Nutrition and food chemistry researchers also use them as reference compounds in in vitro antioxidant activity assays, studies of plant metabolite biosynthetic pathways, and the development of analytical methods for functional food composition.

Example products in this collection: TCI M0121 90-05-1 Guaiacol, TCI B5700 10309-37-2 Bakuchiol, TCI G0011 149-91-7 Gallic Acid, TCI B6085 4481-62-3 Betulonic Acid, TCI C2302 458-37-7 Curcumin (Synthetic), TCI B6443 113558-15-9 Baohuoside I, TCI A0443 29883-15-6 Amygdalin, TCI B6548 33171-05-0 Bisdemethoxycurcumin.

Pay attention to analytical purity, source of isolation, and the crystal form or standard solution suitable for calibration needs of chromatographic methods in analyzing the phytochemical content of a sample. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
