Gardenia jasminoides Ellis, a representative for “homology of medicine and food”, can be used to produce pigment edible oil. Here, aqueous enzymatic extraction (AEE) combined with puffing pre-treatment was explored prepare oil from gardenia seeds. Both wet-heating (WP) at 90 °C dry-heating (DP) 1.0 MPa facilitated the release free by AEE, resulting in highest yields (FOY) 21.8% 23.2% within 3 h...

Liver disease is characterized by inflammation and/or tissue damage that is serious enough to impair hepatic function. Tens of millions of patients are affected by liver diseases worldwide. Geniposide is an irioidglyco compound isolated from Gardenia fruits which has been used for many years in Chinese medicine for the treatment of hepatic disorders and inflammatory diseases. Genipin, the metab...

The iridoid glycoside, geniposide was purified by centrifugal partition chromatography (CPC) with a two-phase solvent system composed of ethyl acetate:isopropanol:water (3:2:5, v/v) from an 80% methanolic extract of fruits of Gardenia jasminoides. Preparative CPC yielded 56.2 mg of geniposide in a one-step separation of 500 mg of extract, with a purity of 95% as determined by HPLC. Isolated gen...

In recent years, saffron has increased in interest for both scientists and consumers, as it is the only spice able to give to food flavor, color and aroma to foods. In relation to flavor, picrocrocin is considered as mainly responsible for saffron’s bitter taste, but other compounds structurally related to picrocrocin and flavonoids have been identified and could contribute to such a property. ...

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...
