چکیده

1. The gas-liquid-chromatographic separations of the acetate, propionate, n-butyrate, isobutyrate and n-valerate esters of androsterone, aetiocholanolone and dehydroepiandrosterone were studied on a 1% neopentyl glycol sebacate column. The n-butyrate, isobutyrate and n-valerate esters were well resolved. 2. The three steroids derived from hydrolysed urinary 17-oxo steroid conjugate extracts were analysed by gas-liquid chromatography after conversion into their n-butyrate esters. The results were compared with independent determinations involving chromatography on alumina.

Synthesis of Novel 17-Oxo-17a-Aza-D-Homo-3, 5-Seco-Steroids as Potential 5α-Reductase Inhibitors

Benign prostatic hyperplasia (BPH) is a non-malignant enlargement of the prostate gland. Itis a leading disorder of the elderly male population. Excessive production of dihydrotestosteronehas been implicated in this pathological condition. Steroidal 5α-reductase is a membrane boundNADPH dependent enzyme which is responsible for the conversion of testosterone (T) todihydrotestosterone (DHT). The...

Detection and Determination of some Migrated Chemicals from Plastic Containers into Different Drinks and Liquids Using Dispersive Liquid-liquid Microextraction Prior to Gas Chromatography

Migration of chemicals from plastic containers into drinks and liquids containing them, is supposed to be a hazardous phenomenon and results in many health problems. Sample preparation is of great importance due to trace amounts analysis of these compounds. In this research, dispersive liquid–liquid microextraction is applied for the extraction and preconcentration of the migrated compounds pri...

Purification and identification of 10-hydroxy-2-decenoic acid from pure royal jelly

The chemical nature of the royal jelly (RJ) has received considerable attention over the past 20 years. Genc and Aslan reported the determination of Trans-10-hydroxy-2-decenoic acid (10-HDA) content in pure Royal Jelly and royal jelly products by column liquid chromatography. Antinelli et al. confirmed this method and evaluated 10-Hydroxy-2-decenoic acid presence as a freshness parameter for Ro...

Method for screening urinary steroids by gas chromatography.

Numerous methods are available for measuring urinary steroids in evaluating endocrine dysfunctions. Measurements of these particular steroids, or groups of them, usually involve tedious isolation methods, corrections for interferences and losses of the steroid, and (or) expensive reagents. We show how gas-liquid chromatography provides a rapid, sensitive, and direct method for several steroid m...
