Two new furan derivatives, (2S,3S,5S)-2-(2-hydroxyethyl)-3-hydroxy-5-(2-hydroxypropan-2-yl)-2-methyltetrahydrofuran (1) and (2S,3S,5S)-2-allyl-3-hydroxy-5-(2-hydroxypropan-2-yl)-2-methyltetrahydrofuran (2), together with six known steroid compounds were isolated from Penicillium sclerotiorum HLL113. 6,9-Epoxy-ergosta-7,22-dien-3-ol (5) was isolated from the genus Penicillium for the first time. Their structures were elucidated on the basis of extensive spectroscopic methods. The test results of α-glucosidase inhibitory activity showed that (22E,4R)-ergosta-7,9(11),22-triene-3β,5α,6β-triol (7) and derrisisoflavone K (8) have significant inhibitory activity.

Key words: Lumnitzera littorea, Penicillium sclerotiorum, secondary metabolite, furan derivative, inhibitory activity against α-glucosidase
