“…This afforded 3.1 g of 1 (xanthoxylin), 225 mg of 2 (methylxanthoxylin), 4.9 g of 3 (scoparone), 2.5 g of 4 (limettin), 82 mg of 5 [6-methoxy-7-(3-methyl-2-butenyl)coumarin], 12 mg of 6 (cedrelopsin), 611 mg of 7 (psoralen), 85 mg of 8 (α-curcumene), 159 mg of 9 (3,6-epidioxy-1,10-bisaboladiene), 42 mg of 10 (eugenol), 209 mg of 11 (methyleugenol) and 55 mg of 12 (sesamin). The compounds were identified by comparison of their 1 H and 13 C NMR spectra with those described in the literature for 1 (Cambie et al, 1991), 2 (Bell and McCaffery, 1992), 5 (Cardona et al, 1992) (supported by NOESY spectra), 12 (Lee and Chang, 2000)…”

“…Lasiodiplodin analogues, effectively inhibiting prostaglandin biosynthesis, 3) and possessing anti-leukemic, 4) antimicrobial, 5) and potato micro-tuber inducing activities, 6) were reported to be isolated from Lasiodiplodia theobromae, [6][7][8] Syncephalastrum racemosum, 9) and Euphorbia fidjiana. 10) In this study, we report the isolation and structure elucidation of three Lasiodiplodin analogues from Sarocladium kiliense. C-NMR spectra of 1 are similar to that of lasiodiplodin 6,7) despite the presence of a oxhydryl at C-6 as evidenced by the downfield signals at δ= 70.5 ppm for C-6 and δ= 3.74 ppm for H-6.…”
