Impact of Zeatin and Thidiazuron on Phenols and Flavonoids Accumulation in Callus Cultures of Gardenia (Gardenia jasminoides)

Iridoids from Gardenia jasminoides Ellis

Three new iridoids, Gardenal-I (1), Gardenal-II (2) and Gardenal-III (3), together with nine known iridoid glycosides; geniposide (4), 6-β-hydroxy geniposide (5), 6-α-hydroxy geniposide (6), 6-α-methoxy geniposide (7), feretoside (8), genipin-1-β-gentiobioside (9), shanzhiside (10), lamalbidic acid (11) and picrocrocinic acid (12) were isolated from EtOH extract of G. gasminoides. The structure...

Selective Extraction of Gardenia Yellow and Geniposide from Gardenia jasminoides by Mechanochemistry.

A novel method for the selective extraction of gardenia yellow and geniposide from Gardenia Jasminoides, based on a mechanochemical method is described. Without the need of complex separation techniques, gardenia yellow compliant with the national standard could be extracted in a simple fashion. The optimal ball-milling conditions determined were as follows: 30% g/g. active carbon milling at 20...

Iridoid-specific glucosyltransferase from Gardenia jasminoides.

Iridoids are one of the most widely distributed secondary metabolites in higher plants. They are pharmacologically active principles in various medicinal plants and key intermediates in the biosynthesis of monoterpenoid indole alkaloids as well as quinoline alkaloids. Although most iridoids are present as 1-O-glucosides, the glucosylation step in the biosynthetic pathway has remained obscure. W...

Anticancer effects of Gardenia jasminoides in HepG2 human hepatoma cells

Gardenia jasminoides is a natural plant, it has many biological activities. Its ability of cancer cell apoptosis needs to be researched. Methods: In this study, the important biological activity materials were determined by high efficiency liquid chromatography. The in vitro anticancer effects were measured by MTT and RT-PCR assays in HepG2 human hepatoma cells. Results: Gardenia jasminoides co...
