The retention time of quercetin (6.445 min), kaempferol (11.246 min), caffeic acid (2.333 min), beta carotene (9.614 min) standards, which were planned to be analyzed by HPLC, was determined. The HPLC conditions that are most suitable for these metabolites have been determined. The amounts of quercetin, kaempferol, caffeic acid and beta carotene in the seedling leaves of these two Calendula species on the 0., 15., 30., 45., 60. days were compared. Caffeic acid and beta carotene have been detected in the leaves. However, quercetin and kaempferol compounds were not detected. It was determined that the caffeic acid and beta carotene amounts of C. officinalis species were higher than that of C. arvensis. The highest caffeic acid in both C. officinalis and C. arvensis seedlings (0.4042±0.0123 ...

Digitalis species have been used as a source of these components for many years. Digitalis trojana Ivanina is an endemic plant of Ida Mountain (KazdagA±), Canakkale, Turkey. In this study, we report the cardenolide content changes of Digitalis trojana Ivanina which was collected from KazdagA± at different altitudes (836m, 961m, 1041m and 1191 m). The content of lanatoside C, digoxin, digitoxin and gitoxigenin in the plant samples were analysed by HPLC. According to the results of analyses, cardenolide contents of D. trojana (lanatoside C, digoxin, digitoxin and gitoxigenin) showed variations by altitude (836m, 961m, 1041m and 1191 m) and month (May and July). It was determined that these cardenolides were higher in plants collected in July than in May and the highest cardenolide concentration was found in the samples collected at 1047 m. both in May and July.

According to this, four weeks old seedlings were treated with 0.04 mL/L, 0.08 mL/L and 0.16 mL/L concentrations of dodine. Then, the leaves of plant samples were harvested with 24, 48 and 72 hours intervals. Our results have showed that while the total protein content were decreased significantly, POX activity was increased with the increased concentration of dodine and exposure time when compared with control seedlings. This research have shown that dodine can stimulate the plant defense system.
