Stevia Extract

[Characteristics]

Stevia sugar features high sweetness and low calorie and its sweetness is 200 350  times of that  of cane sugar but its calorie is only 1/300 of that of cane sugar.

The component of stevia extract that gives it its sweetness is a mixture of various steviol glycosides. The components of sweetness in stevia leaves are stevioside, rebaudioside A, C, D, E and dulcoside A. Rebaudioside C, D, E and dulcoside A are small in quantity. The principal components are stevioside and rebaudioside A.

The quality of stevioside and rebaudiosideA is better than those of other components, which are commercially extracted and used in various applications.

The steviol glycosides present in stevia extract are referred to as “steviosides” or ¡°stevia extract¡±. Among these “steviosides”, the most common is Stevioside followed by RebaudiosideA. The Stevioside has a slight and pleasant herbal taste and the Rebaudioside-A has no herbal taste.

Although Rebaudioside C and dulcoside A are small in quantity in stevia extract, they are the major components giving bitter aftertaste.

[Function]

A large number of pharmaceutical tests have proved that stevia sugar has no side effects, carcinogens, and is safe for eating.

Compared with cane sugar, it can save 70% of the cost. With pure white color, pleasing taste and no peculiar smell, Stevia sugar is a new sugar source with broad perspective for development. Stevia rebaudianum sugar is the natural low hotsweet agent mostly similar to the flavor of cane sugar, approved to be used by State Ministry of Health and Ministry of Light Industry.

It is the third natural succedaneum of cane sugar and beet sugar with development and health care value, extracted from the leaves of the herbal vegetable of the composite family-stevia rebaudianum.

About the Speaker

Dr. Amy Wright is formally trained as an organic chemist and has spent the past 35 years exploring the chemistry of marine organisms with the goal of identifying natural products with the potential to change how we treat dread diseases. Much of her work has focused on organisms collected in deep water habitats using tools such as the Johnson-Sea-Link submersibles. She received her B.S. from California State University at Dominguez Hills and her MSc and Ph.D. in Organic Chemistry from the University of California at Riverside.

About the Lecture

Wherever there is biological diversity there is chemical diversity and this diversity leads to opportunities for finding new medicines. Many plants, marine animals and microbes produce small organic molecules, “natural products”, that provide advantages to the organisms that make them which range from attracting mates to repelling or even poisoning predators.

These same natural products often show activity in human health applications and over 46% of the small molecule medicines used today have their origin in natural products. The talk will discuss the HBOI natural products library and how we are using it to look for new compounds with the potential to treat cancer, tuberculosis, multi-drug resistant bacterial infections, and Alzheimer’s disease.
