Artonin K is found in jackfruit and fruits. 5a,6-Dihydro-1,3,8-trihydroxy-10-methoxy-5,5-dimethyl-5H,7H-benzofuro[3,4-bc]xanthen-7-one C21H18O7 382.3634 382.10525293 8,17,19-trihydroxy-6-methoxy-14,14-dimethyl-3,15-dioxapentacyclo[11.6.1.0²,¹¹.0⁴,⁹.0¹⁶,²⁰]icosa-1(20),2(11),4(9),5,7,16,18-heptaen-10-one artonin K 148719-61-3 COC1=CC2=C(C(O)=C1)C(=O)C1=C(O2)C2=C3C(C1)C(C)(C)OC3=C(O)C=C2O InChI=1S/C21H18O7/c1-21(2)10-6-9-18(25)16-11(22)4-8(26-3)5-14(16)27-19(9)17-12(23)7-13(24)20(28-21)15(10)17/h4-5,7,10,22-24H,6H2,1-3H3 NMKFZSNRHNHWLX-UHFFFAOYSA-N belongs to the class of organic compounds known as xanthones. These are polycyclic aromatic compounds containing a xanthene moiety conjugated to a ketone group at carbon 9. Xanthene is a tricyclic compound made up of two benzene rings linearly fused to each other through a pyran ring.
