The caffeic acid derivatives with chlorogenic add at R, 0.45 (Tl) and isochlorogenic acids at RfO. 7-0.8 are more concentrated in Abrotani herba (1) than in Fabiani herba (2). The later shows rutin at Rf — 0.4 as a prominent orange zone and tlie violet-blue Zone of scopoletin-7-O-primveroside at Rf 0.15.

Fig. 5A,B Arnicae flos (1,4). Arnica montana (1) and Arnica chamissonis (4) show a similar TLC pattern of three orange-yellow flavonoid zones between the blue zones of chlorogenic acid (Rf — 0.45/Tl) and isochlorogenic acids (Rf 0.7-0.95/Tl), The upper zone is due to isoquercitrin and luteolin-7-O-glucoside (T4). The flavonoid glycoside zone in the R, range of hy peroside (3T/T2) is more highly concentrated in sample (4).

Phenolic compounds include a wide range of secondary metabolites that are biosynthesised from carbohydrates through the shikimate pathway [14]. This is the biosynthetic route to the aromatic amino acids, phenylalanine, tyrosine, and tryptophan, and only occurs in microorganisms and plants. In the first step, the glycolytic intermediate phosphoenol pyruvate and the pentose phosphate intermediate erythrose-4-phosphate are condensed to 3-deoxy-D-arabino-heptulosonate 7-phosphate (DAHP), a step catalysed by DAHP synthase. Intermediates of the shikimate pathway are 3-dehydroquinate, shikimate, and chorismate (Fig. 1). Phenylalanine is biosynthesised from chorismate, and from phenylalanine all the phenylpropanoids. Quinate is produced from 3-dehydroquinate and incorporated into chlorogenic and isochlorogenic acids (caffeoyl quinic acids) by combination with caffeic acid. Gallic acid is produced from shikimate.

An HPLC study of the individual phenolic acid derivatives showed chlorogenic acid to be the predominant compound in potato (22-71 mg/kg). Cryptochlorogenic acid (11 mg/kg), neochlorogenic acid (7 mg/kg) and isochlorogenic acid (4,5-dicaffeoyl quinic acid) (Fig. 4) (3 mg/kg) were also present in smaller amounts [80]. It was also demonstrated that caffeic acid compounds are not distributed uniformly in the tuber, but occur in strongly decreasing concentrations from the outer to the inner section. About 50% of the compounds as a whole are located in the potato peel and adjoining tissue. [Pg.764]

Caffeic, p-coumaric, ferulic, and sinapic acids (Fig. 4) and their esters and glycosides have all shown interesting antioxidant activity [122 123]. 3,5-Dicaffeoyl-4-succinylquinic acid and 3,5-dicaffeoylquinic acid (isochlorogenic acid) showed antioxidant activity in a P-carotene-linoleate method [123].
