Determination of Tocotrienols and Tocophenrols Using HPLC-ECD
Figure 1. Structures of the various tocopherol and tocotrienol vitamers. Introduction There are eight vitamers of vitamin E (alpha-, beta-, gamma-, and delta-tocopherols and the corresponding tocotrienols) (Figure 1), differing in their biological activity and distribution in foods. Most often vitamin E’s role is usually associated with its antioxidant activity. For example, α-tocopherol is a w...
متن کاملGlucopyranosylidene-Spiro-Thiazolinones: Synthetic Studies and Determination of Absolute Configuration by TDDFT-ECD Calculations.
Reactions of O-peracylated C-(1-bromo-β-d-glucopyranosyl)formamides with thioamides furnished the corresponding glucopyranosylidene-spiro-thiazolin-4-one. While O-debenzoylations under a variety of conditions resulted in decomposition, during O-deacetylations the addition of MeOH to the thiazolinone moiety was observed, and with EtOH and water similar adducts were isolated or detected. The stru...
متن کاملErdheim–Chester disease (ECD)
BACKGROUND Erdheim-Chester disease (ECD) is an uncommon aggressive, multisystem form of non-Langerhans' cell histocytosis, which was firstly reported by Jakob Erdheim and William chester in 1930. The disease pathological features encompass an aberrant multiplication, overproduction and accumulation of white blood cells called histiocytes within multiple tissues and organs. Herein, we present a ...
متن کاملThe Ecdysoneless (ecd
Ring glands dissected from homozygous l(3)ecd1 ts wandering larvae and upshifted in vitro to the restrictive temperature, 29°C, synthesize abnormally low quantities of ecdysteroid. Nevertheless, ecd1 ring glands retain the ability to respond at 29°C to an extract prepared from wild-type larval neural tissues that presumably contain prothoracicotropic hormone (PTTH), although both basal and stim...
متن کاملGood Computational Practice in the Assignment of Absolute Configurations by TDDFT Calculations of ECD Spectra.
Quantum-mechanical calculations of chiroptical properties have rapidly become the most popular method for assigning absolute configurations (AC) of organic compounds, including natural products. Black-box time-dependent Density Functional Theory (TDDFT) calculations of electronic circular dichroism (ECD) spectra are nowadays readily accessible to nonexperts. However, an uncritical attitude may ...
