2.6 Other Polyketides
Penicitrinols G and H (162 and 163) (Fig. 10) were isolated from the liquid glucose,
yeast, and malt (GYM) medium cultivation of Penicillium citrinum SCSGAF0167,
as obtained from the gorgonian Echinogorgia aurantiaca collected from Sanya,
Hainan Province [34]. Xylariaceae sp. SCSGAF0086 was obtained from the gorgonian Melitodes squamata collected from the South China Sea. The liquid PDB
