lamps; if available, a thin layer plate densitometer with fluorescent capability, excitation wavelength 365 nm and emission wavelength > 400 nm. d) TLC plate sprayer – Kontes, K-422540 e) Blender – waring, equipped with 1 L jar and lied f) Filter paper – Whatman 2V folded circles, 24 cm g) Vials – 5 mL, conical, tapered inside, with Teflon-lined screw cap Reagents a) Solvents – reagent grade acetonitrile, hexane, methylene chloride, benzene, methanol, acetic acid, and anhydrous ethyl ether. (Caution: Benzene is a suspected carcinogen. Use necessary safety measures when handling this chemical) b) Silicone DC-200 – 12 500 centistokes c) Silicone-ether spray – silicone-anhydrous ether (18 + 82). If weighing silicone is more convenient, 1g = 1mL d) Potassium chloride solution – dissolve 4g KCl in 100 mL water e) Aluminium chloride solution – Dissolve 15 g AlCl, in ethanol and dilute to 100mL f) Calcium chloride – anhydrous, granular (8mesh). Prepare in advance CaCl2 –water (1 + 2, w/v). Hasten solution by placing in ultrasonic bath. Remove slight cloudiness by filtering through Whatman 2V paper g) Curpic carbonate, Cu (II) – Reagent grade powder h) Diatomaceous earth – Hyflo Super- Cel i) Sterigmatocystin standards – Stock standard – Prepare according to sec. 26.133. Working standard – Dilute stock standard to ca ng/ μL benzene j) Boiling chips – Si C. Float off fines and extraneous particles with water, wash with acetone, and dry. Extraction Weigh 36 G composited sample into 1L Waring blender jar. Add 170 mL acetonitrile and 30 mL KCl solution; secure lid and blend 3 min at high speed. Decant extract through Whatman 2V paper. Transfer 50 mL filtrate to 250 mL separatory funnel, add 50 Ml CaCl2 solution, vigorously shake ca 30 s, and let stand until layers separate; separation usually occurs within 5 min. Discard bottom layer. Remove excess water from inside the stem of the separatory funnel by drying with laboratory wiping tissue, such as Kimwipes. Place a small wad of glass wool into the stem of the separatory funnel to serve as a filter and drain the remaining phase into a second separatory funnel. Add 50 Ml water to remaining phase and mix. Add 50 mL hexane, vigourously shake about 1 min, and let layers separate. Transfer bottom layer to another 250 mL separatory funnel. Extract, using 50 and 25 mL portions of methylene chloride, by shaking first extraction 1 min and second extraction 10 s. Again, complete separation usually occurs within 5 min. Collect methylene chloride extracts separately and save for column chromatography. 562
Column Chromatography Loosely place glass wool plug in bottom of chromatographic tube and add ca 15 g anhydrous sodium sulfate. Add 4 g cupric carbonate-diatomaceous earth (1 + 2); lightly pack column by holding in upright position and by allowing it to drop gently on its tip onto book or writing pad. Add 20 g sodium sulfate to top of column. Sequentially pass methylene chloride extracts through column, beginning with 50 mL portion. Collect that eluate and each successive eluate in 250 mL Philips beaker. Add 25 mL portion to column when first portion has drained to below top layer of sodium sulfate. Rinse column with 10 mL methylene chloride. Add 4-5 SiC boiling chips to Philips beaker and evaporate solvent nearly to dryness on steam bath under gentle stream of nitrogen. Cool to room temperature and quantitatively transfer with small portions of methylene chloride to 5 mL vial. Evaporate solvent to dryness under gentle stream of nitrogen. Save sample residue for TLC. This Layer Chromatography Add 100 μL benzene (screen < 10 ppb) or 200 μL benzene (screen1 h before using. Spot plate as previously described and develop using benzene-methanol (95 + 5). Solvent front travels 13-15 cm in 45 min. 563
