    • A suspension of disrupted mycelium (2 ml) in sterilised water was added to each of twenty 1000 ml conical flasks, containing 200 ml of sterilised 2% potato dextrose broth (Difco). The flasks were shaken at 200 rpm for two weeks at 27 °C. The harvested filtrate was then extracted with Diaion HP20 resin (400 ml; Mitsubishi) which had previously been washed with HPLC grade methanol (Merck) and thoroughly conditioned with distilled water. The resin was removed, washed with distilled water (2 × 1000 ml) and eluted with HPLC grade methanol (2 × 1000 ml). The methanolic eluant was evaporated to dryness. Vacuum/liquid chromatography was used to purify the three products, 1, 2 and 3. Column eluant (4.2 g) was dissolved in chloroform (15 ml), to which was added silica gel (flash chromatography grade; BDH; 6 g) and evaporated. The slurry was applied to the top of a 60 mm diameter silica gel column. The column was eluted with 100 ml volumes of n-hexane/ethyl acetate mixtures, beginning with 100% n-hexane followed by sequential stepwise 10% increase in ethyl acetate, with a final elution of 10% methanol/ethyl acetate. On evaporating the column fractions, three were noticed to contain white needles within a yellow oil. Millilitre quantities of methanol, ethyl acetate, diethyl ether and chloroform were used to remove the oil and afford pure white needles of 1. Compound 2 was eluted from the silica column with 80% ethyl acetate/n-hexane, 3 in 90% ethyl acetate/n-hexane and 1 with 10% methanol/ethyl acetate.
