A new triterpene named as alysinol 3 f , 22 g -dihydroxyolean-12-ene 1 along with known compounds usnic acid, methyl 2,4-dihydroxy-3,6-dimethyl benzoate, 3-hydroxy benzoic acid, stigmasterol, poriferasterol and ursolic acid have been isolated from Alysicarpus monolifer . The structure of 1 has been established through spectroscopic techniques. 

New butyrylcholinesterase inhibitory triterpenes fromSalvia santolinifolia

Slavins A (1) and B (2), the new amyrin type triterpenes, have been isolated from the chloroform soluble fraction ofSalvia santolinifolia and assigned structures on the basis of spectral studies

5,7-Dihydroxy-3,6-dimethoxy-2-(4-methoxyphenyl)-4H-chromen-4-one monohydrate

The title compound, C18H16O7·H2O, is a flavonoid isolated from Dodonaea viscosa that is involved in extensive hydrogen bonding, assembling the molecules into a supramolecular network via classical intermolecular O—H⋯O hydrogen bonding.

Biologically active C-alkylated flavonoids from Dodonaea viscosa

All the compounds exhibited mild inhibition against urease but remained recessive in case of α-chymotrypsin, and the structures of all compounds were established on the basis of 1D and 2D NMR spectroscopy and mass spectrometry.
