The present invention provides a method of isolating at least one ingredient with anti-viral efficacy from
Baphicacanthus cusia.
The ingredient can be an alkaloid, a triterpenoid, a lignan, a phenylethanoid, a sesquiterpene lactone, or a flavonoid. Two new alkaloids are produced, which have not been previously reported. Moreover, the method isolates 12 compounds which could not or have not been previously isolated. A pharmaceutical composition includes the at least one ingredient and at least one pharmaceutical tolerable excipient. A method of treating a subject suffering from a viral disease includes administering at least one ingredient isolated from
Baphicacanthus cusia.

A set of 12 maslinic acid–coumarin conjugates was synthesized, with 9 being maslinic acid–diamine–coumarin conjugates at the C-28 carboxylic acid group of triterpene acid and the other three being maslinic acid–coumarin conjugates at C-2/C-3 and/or C-28 of the triterpene skeleton. The cytotoxic effects of these 12 triterpene conjugates were evaluated in three cancer cell lines (B16-F10, HT29, and Hep
