title: [Studies on the chemical constituents of Annona squamosa].
abstract: Twelve compounds were isolated from Annona squamosa. Their structures were identified as liriodenine (AS-1), moupinamide (AS-2), -(-)-kauran-16 alpha-ol-19-oic acid (AS-3), 16 beta, 17-dihydroxy-(-)-kauran-19-oic acid (AS-4), anonaine (AS-5), 16 alpha, 17-dihydroxy-(-)-kauran-19-oic acid (AS-6), (-)-isokaur-15(16)-en-17,19-dioic acid (AS-7), squamosamide (AS-8), 16 alpha-methoxy-(-)-kauran-19-oic acid (AS-9), sachanoic acid (AS-10), (-)-kauran-19-al-17-oic acid (AS-11), daucosterol (AS-12). Among them, AS-8 is a new amide, AS-9 is a new natural product.
