The anthraquinones of mangrove endophytic fungus Alternaria sp. SK6YW3L isolated from Guangxi Shankou
sp. SK6YW3L were studied. The fungus was isolated from the fresh fruit of mangrove plant
Sonneratia apetala
collected from Guangxi Shankou Mangrove Nature Reserve. The strain was fermented and cultured with 3% salinity rice medium, and then subjected to silica gel column chromatography, semi-preparative HPLC, Sephadex LH-20, ODS and recrystallization. Thirteen anthraquinones including 7-acetyl-1,3,6-trihydroxyanthracene-9,10-dione (
), were identified using modern spectroscopy techniques such as 1D, 2D NMR and MS, and then comparing with literature data. The single crystal structure of compounds
1
and
4
were analyzed by single-crystal X-Ray diffraction experiment using CuK
α
radiation. Among them, compound
1
was obtained as a new single crystal, and the absolute configuration of compound
4
was determined to be 5
R
, 6
S
, 7
R
, 8
S
. The absolute configurations of other compounds were determined by comparing optical rotation and CD data. In the bioactivity assay, compounds

exhibited
α
-glucosidase inhibitory activity with IC
50
values of (210.1 ± 1.2), (125.8 ± 1.5) and (68.7 ± 1.3) μmol/L, respectively.
