Approved: Paclitaxel is a very important anticancer drug commonly called Taxol ®. We know from previous work (Hoffman, et al., 1998) that Taxol exists in filbert, Corylus avellana L. material. Quantification of Taxol in filbert plant material is painstaking and hitherto was accomplished by rapidly processing single batches in a complicated procedure (Hoffman, et al., 1998), which seemingly unav...
PURPOSE To characterize gene expression patterns in guinea pig ocular tissues and identify orthologs of human genes from NEIBank expressed sequence tags. METHODS RNA was extracted from dissected eye tissues of 2.5-month-old guinea pigs to make three unamplified and unnormalized cDNA libraries in the pCMVSport-6 vector for the lens, retina, and eye minus lens and retina. Over 4,000 clones were...
Objectives: This study aimed to compositionally characterize the biosurfactant and its application in crude oil bioremediation. Methods: Production of was carried out Bushnell Hass Broth (BHB), supplemented with 1% glucose. Compositional characterizations were performed by 1H-NMR ESI-MS analysis. The biodegradation using a 0.1% (g/v) purified (ENO14BS). experiment has three sets namely Set A, B...
Four new bibenzyl derivatives were isolated, together with other known bibenzyls, by bioassay-guided fractionation of a CHCl₃-MeOH extract of Notholaena nivea Desv. (Pteridaceae) aerial parts. The structures were elucidated by NMR, ESIMS and other spectral analyses. Their antioxidative effects towards superoxide, lipidic peroxidation and the 2,2'-azino-bis-3-ethilbenzothiazoline-6-sulfonic acid...
Two new flavonol glycosides, myricetin 4'-O-alpha-L-rhamnopyranoside (1) and quercetin 3'-O-alpha-L-rhamnopyranoside (2), together with a novel biflavonol compound, speciin (3), as well as eleven phenolic metabolites, namely myricitrin (4), europetin 3-O-alpha-L-(1)C(4)-rhamnopyranoside (5), quercitrin (6), hyperin (7), rhamnetin 3-O-beta-galacto-pyranoside (8), caffeic acid (9), caffeic acid m...
The purpose of this study is to elucidate both the chemical and conformational structure of an unfractionated fucoidan extracted from brown seaweed Turbinaria ornata collected at Nha-trang bay, Vietnam. Electrospray ionization mass spectrometry (ESI-MS) was used for determining the chemical structure and small angle X-ray scattering (SAXS) provided conformational of the structure at the molecul...
