5. A New Tetraglycosylated Flavonoid from Leaves of Platycyamus regnellii Benth. Isolated by High-Speed Countercurrent Chromatography
A new tetraglycosylated flavonoid derivative of kaempferol was isolated from the butanol extract of leaves of Platycyamus regnellii (Fabaceae) using high-speed countercurrent chromatography (HSCCC). The butanol extract (960.5 mg) was initially fractionated with the solvent system EtOAC-BuOH-H2O 2:8:10 (v/v/v) (elution in normal phase mode). The fractions con

6. 2-Methyl 2-butanol suppresses human retinoblastoma cells through cell cycle arrest and autophagy
2-Methyl-2-butanol (MBT) is a chemical compound from the group of alcohols more specifically pentanols, which has shown an excellent anti-cancer activity in our previous study. However, its mechanism of action remains unclear. The present study was designed to investigate the anti-cancer effect of MBT on human retinoblastoma cells. The results showed that th

7. Measurement of Activity Coefficients at Infinite Dilution for Alcohols in [BMIM][CH3SO4] using HS-SPME/GC-FID
ABSTRACT The activity coefficient at infinite dilution (&IN1) and distribution ratios at infinite dilution (&IN2) were determined for alkanols (methanol, ethanol, 1-propanol, 1-butanol, 2-butanol, and 2-methyl-2-propanol) in the ionic liquid (IL) 1-butyl-3-methylimidazolium methyl sulfate ([BMIM][CH3SO4]) by HS-SPME (Headspace - Solid Phase Micro Extraction

8. Study of Viability of Solid-Phase Microextraction, in vivo, in the Extraction of Microbial Volatile Organic Compounds Associated to the Pigment Production Process by the Monascus Fungus, in Submerged Fermentation
Microbial volatile organic compounds (MVOCs) are present in several production processes in biotechnology. In this study it is evaluated the viability of use of a method involving solid-phase microextraction (SPME), in vivo SPME, in the extraction of MVOCs, associated with the pigment production process by the Monascus fungus. PDMS/Car/DVB (50/30 µm) fiber

9. A cytotoxic C-glycosylated derivative of apigenin from the leaves of Ocimum basilicum var. thyrsiflorum
ABSTRACT The standardized 80% ethanolic extract of the leaves of Ocimum basilicum var. thyrsiflorum (L.) Benth., Lamiaceae, growing in KSA, exhibited a significant antioxidant activity compared to the ethyl acetate and butanol extracts, which was correlated to its higher phenolic and flavonoid contents. Chromatographic separation of the 80% ethanol extract r

10. Identification of volatile compounds in cultivars barker, collinson, fortuna and geada of avocado (Persea americana, Mill.) fruit
Abstract The objective of this paper was to determine the volatile profile of four cultivars - Barker, Collinson, Fortuna and Geada of avocado (Persea americana, Mill.) fruit and to perform a detailed study on the effect of volatiles extraction conditions. The best conditions for extraction for Collinson and Fortuna cultivars were by using a mixture of penta

11. INFLUENCE OF FUSEL OIL COMPONENTS ON THE DISTILLATION OF HYDROUS ETHANOL FUEL (HEF) IN A BENCH COLUMN
AbstractThe components of fusel oil form azeotropes with water, resulting in challenges in obtaining hydrous ethanol fuel (HEF) and increasing investment and operating costs. The aim of this study was to evaluate how the presence of fusel oil affected HEF distillation. Mixtures of ethanol (6.0 to 6.5 % w/w) and water (93.0 to 94 % w/w) containing different c

12. A fração volátil das aguardentes de cana produzidas no Brasil
The volatile fraction of sugar cane spirits plays a key role in the quality and acceptance of these beverages. The composition of this fraction is dependent on the way sugar cane collection, fermentation, distillation and aging are carried out. The materials used in these processes strongly influence chemical composition. Acetic acid, acetaldehyde, ethyl ace
