Iridal-Type Triterpenoids with a Cyclopentane Unit from the Rhizomes of Belamcanda chinensis

ABSTRACT Belamcanda chinensis is an ornamental plant cultivated as a medicinal herb in its countries of origin: China and Japan. It is propagated by rhizomes and seeds, but little is known on the optimal conditions for its germination. This study aimed to assess germination temperatures and treatments to overcome its seed dormancy. Two experiments were conducted: the first evaluated the effects of constant temperatures of 20 ºC, 25 ºC and 30 ºC (in the dark) and 20-30 ºC with light (8-h photoperiod), while the second one involved the removal of combinations from the seed tegument structure (with and without tegument), with pre-hydration at 7 ºC, 30 ºC or no pre-hydration, in addition to an extra treatment without tegument or pre-hydration. Alternating the temperature results in better effects on the variables evaluated, while, at constant temperatures, there is little or no germination. The removal of the outer tegument structure and from seeds pre-hydrated at 30 ºC accelerates the germination process.

And Function

The genus Iris consists of approximately 360 species and is distributed to Eurasia, North Africa, and North America. Belamcanda chinensis was incorporated into the genus Iris by APG III as Iris domestica. Iris species have also been cultivated as ornamentals since ancient times. Many flavonoids are isolated and identified from the flowers, leaves, and rhizomes. So far as we know, 6 anthocyanidins, 13 flavones, 20 flavonols, 20 C-glycosylflavones, 14 flavanones, 11 dihydroflavonols, 6 flavan and proanthocyanidins, and 85 isoflavonoids were reported as aglycones and glycosides. However, chalcones, dihydrochalcones, aurones, biflavonoids, and neoflavonoids are not found in the genus Iris. Fifteen xanthones that are related to flavonoids were also isolated from Iris species. In this review, we describe the flavonoids and xanthones that were isolated and characterized from Iris species. Moreover, their phytochemistry, contribution to the flower colors, relationships with taxonomy, and activities and functions are also discussed.
