Iteamine, the first alkaloid isolated from Itea virginica L. inflorescence

Synthesis of allitol from D-psicose using ribitol dehydrogenase and formate dehydrogenase

“…Optimization of various reaction parameters results in high-yield allitol production under experimental conditions, such as shaking velocity and shaking type, via the reduction of Dpsicose by RDH and irreversible regeneration of NADH from NAD + by FDH. The allitol produced is pure, being successfully characterised and confirmed by HPLC, IR, and 13 C NMR analyses. Thus, low-cost production of allitol on a comparatively large scale using these novel enzymes can in turn extend the range of applications of allitol to pharmaceuticals and other types of food in future.…”

“…Among these, allitol is a rare hexitol that is synthesised by the reduction of D-psicose [12]. In the natural world, allitol is present in plants of the Itea genus (Itea virginica L.) and certain fungi [13,14]. Izumori [10] reported a useful strategy for processing most hexoses, called the Izumoring map, in which allitol and galactitol are placed at symmetric points of D and L in the production zone of hexose sugars.…”

Recent advances in d -allulose: Physiological functionalities, applications, and biological production

“…D-Allulose is very rare in nature, and is found in small quantities in Itea and wheat, which are its few plant source (Ayers et al, 2014;Miller & Swain, 1960), and in certain bacteria (Zhang, Mu, Jiang, & Zhang, 2009). D-Allulose is not present in animals.…”

Allitol: production, properties and applications

“…Natural allitol is extracted from Itea virginica L, a plant native to North America that contains D-psicose and allitol, and allitol is an active metabolite in Itea plants (Hough & Stacey, 1963, 1966aCarr et al, 1968;Hough et al, 1973;Ayers et al, 2014). It is also present in Tylopilus plumbeoviolaceus, a fungus widely distributed in Yunnan Province, China (Wu et al, 2000).…”
