Secondary Products from Plant Tissue Culture

Plant Secondary Compounds; Their

Both the anti-nutritional and beneficial effects of secondary compounds in a range of temperate and tropical forages have been reviewed. Major secondary compounds in temperate and tropical forage plants occur in the phenolic fraction and include condensed and hydrolysable tannins, phenolic monomers and lignin. Condensed tannins (CT) bind to plant protein by pH-reversible hydrogen bonding. In te...

An Evaluation of Analytical Methods for the Detection of Secondary Oxidation Products in Dedifferentiated Plant Cultures

BREMNER D.H., MAGILL WJ. DEIGHTON N.& BENSON E.E. 1997. An evaluation of analytical methods for the detection of secondary oxidation products in dedifferentiated plant cultures.-Phyton (Horn, Austria) 37 (3): (39) (44). A range of techniques have been employed to detect and examine aldehydic products of lipid peroxidation in D. carota cultures. Emphasis is placed on the use of HPLC and LC-MS te...

Secondary Plant Products Causing Photosensitization in Grazing Herbivores: Their Structure, Activity and Regulation

Photosensitivity in animals is defined as a severe dermatitis that results from a heightened reactivity of skin cells and associated dermal tissues upon their exposure to sunlight, following ingestion or contact with UV reactive secondary plant products. Photosensitivity occurs in animal cells as a reaction that is mediated by a light absorbing molecule, specifically in this case a plant-produc...

Isolation of secondary products from Ipomoea digitata – a medicinally important plant

The paper reports the isolation and characterization of β-sitosterol, t-cinnamic acid [undecyl (E)-3-(4hydroxyphenyl)-2-propenoate], an unknown coumarin and a lignan type resin glycoside from the tuberous roots of Ipomoea digitata. The structures of the compounds were elucidated on the basis of extensive chemical and spectroscopic data. Importantly, one of the compounds exhibited significant an...
