Ipomoea turpethum R. Br. [= Operculina terpethum (Linn.) Silva Manso (Hindi—Nisoth, Pitohri), a perennial plant with a muchtwisted stem is found through out India. It is reported to be highly medicinal and is cultivated occasionally in gardens as an ornamental plant. Some hydroxy fatty acids, butulin, lupeol and sitosterol have been found in the plant. Seed gums are important vegetable products...

The objective of this work was to study the quality of guar and guar gum produced in Sindh, Pakistan. Fresh guar, guar seeds and guar gum made in laboratory was analyzed for that purpose. For comparison purpose, analytical grade guar gum and industrial guar gum (prepared from guar split) was also studied. Results of proximate composition of guar seed revealed that it is mainly composed of Nitro...

Aminooxyl sugar derivatives are versatile building blocks for the generation of various glycoconjugates with interesting bioactivities. We report herein a synthetic method for the preparation of orthogonally protected glycoaminooxy acid from methyl α-d-glycopyranoside in 7 steps. The key steps involve the selective protection, O-alkylation and Mitsunobu reaction. Fully deprotected N-oxyamide-li...

A nitriloside is a naturally occurring or synthetic compound which upon hydrolysis by a betaglucosidase yields a molecule of a non-sugar, or aglycone, a molecule of free hydrogen cyanide, and one or more molecules of a sugar or its acid. There are approximately 14 naturally occurring nitrilosides distributed in over 1200 species of plants. Nitrilosides are found in all plant phyla from Thalloph...

the effects of some synthetic sweeteners on the rheological and physical properties of guar gum in dilute solutions were investigated.measurements include the determination of intrinsic viscosity and the particle size, surface weighted mean [d3, 2], volume weighted mean [d4,3] and specificsurface area ofguar gum andsyntheticsweeteners mixtures. the concentration of these sweeteners were 0, 0.1,...

the aim of this study was to investigate the effect of the addition of commercial lipase in various forms on the acceleration of the ripening of uf-feta cheese. commercial lipase from aspergillus niger was encapsulated by using silica composition based on sol-gel method. lipase was then added to cheeses in three forms, namely, free lipase, encapsulated lipase, and encapsulated lipase with arabi...

Background: Sugar alcohols such as xylitol are incorporated in a number of oral hygiene products for their anti-cariogenic properties while chewing gum is known to be beneficial to oral hygiene. Objective: The aim of this study was to determine the composition of the dental plaque microbiota in patients with active caries before and after using a chewing gum supplemented with maltitol. Design :...

Dental caries is a pandemic infectious disease which can affect the quality of life and consumes considerable health care resources. The chewing of xylitol, sorbitol, and even sugar gum has been suggested to reduce caries rates. No clinical study has simultaneously investigated the effectiveness of these gums when compared with a group receiving no chewing gum. A 40-month double-blind cohort st...
