Following the characterization of hypoglycemic, gastric emptying inhibitory, and gastroprotective principles and the structure elucidation of calendasaponins A, B, C, and D, two new ionone glucosides (officinosides A and B), and two sesquiterpene oligoglycosides (officinosides C and D), were isolated from the flowers of Egyptian Calendula officinalis. The structures of the officinosides were el...

Enabling technologies in synthetic biology now present the opportunity to engineer wine yeast for enhanced novel aromas. In doing so, improved products will increase desirability of consumer and add value winemaker. The action enzyme carotenoid cleavage dioxygenase 1 (CCD1) on ?-carotene produce ?-ionone is interest improve aroma flavour wine. Engineering yeast, Saccharomyces cerevisiae, higher...

Biosynthesis, Carotenoids, /?-Carotene, Photosynthesis Two /7-Carotene pools were obtained in the chloroplast. It is concluded that one pool is very small like a-carotene and responsible exclusively for the biosynthesis of /?-ionone-xanthophylls. The other ^-carotene pool is proposed to be the one, that is located close to photosystem I and is involved in photosynthesis as a light protecting ag...

A new ionone glycoside, frehmaglutoside I (1), and three new rhemaneolignans A-C (2-4) were isolated from the 95% EtOH extract of the roots of Rehmannia glutinosa. Their structures were determined by extensive spectroscopic (UV, IR, HR-ESI-MS, 1D and 2D NMR) analyses. In addition, these compounds were evaluated for their protective effects on cardiocytes impaired by doxorubicin in H9c2 cells. A...

A maize plant (Zea mays) planted in a test tube was found to inhibit the growth of the soil-borne plant pathogen, Fusarium oxysporum f. sp. melongenae. The antifungal compounds, 6-methoxybenzoxazolinone and 6,7-dimethoxybenzoxazolinone, were isolated from an ethanol extract of Zea mays roots, and (6R)-7,8-dihydro-3-oxo-alpha-ionone and (6R,9R)-7,8-dihydro-3-oxo-alpha-ionol were isolated from th...

the leaves of arum conophalloides (araceae) were used in some west areas of iran as a dessert. the aerial parts of the herb were collected from sahneh mountains, kermanshah province, west of iran and was hydrodistilled by klevenger-type apparatus. composition of the essential oil was determined by gc and gc/ms. totally, 18 components (92% of total essential oil) were identified. the oil contain...

The leaves of Arum conophalloides (Araceae) were used in some west areas of Iran as a dessert. The aerial parts of the herb were collected from Sahneh Mountains, Kermanshah Province, West of Iran and was hydrodistilled by Klevenger-type apparatus. Composition of the essential oil was determined by GC and GC/MS. Totally, 18 components (92% of total essential oil) were identified. The oil contain...

External environmental factors affect the appearance of plants, specifically their color and aroma. To investigate effects on ornamental quality Osmanthus fragrans, which has bright colors a strong floral fragrance, contents characteristic flower aroma compounds under different light temperature treatments were investigated in O. fragrans ‘Houban Yingui’. The content compound β-carotene decreas...
