The sticky resin discharge from the leaf buds of Gardenia lucida is in the form of yellow tears having an offensive smell and bitter taste (Suryanarayana et al., 2012). The resinous gum of Gardenia lucida is locally known as Dikamali gum.

Current investigations have also revealed that Dikamali possesses a broad spectrum of biological activities such …show more content…

lucida (1.0 kg) was extracted with methanol (4  21L) by percolation at room temperature (25±5o). The methanol extract was dried in vacuo to give a residue (675.0g). The residue was suspended in water and subsequently partitioned between hexane, chloroform and n-butanol. Chloroform extract (180 g) was chromatographed over silica gel column eluting with a gradient system of hexane: ethylacetate. Fractions (236-306), eluted with hexane: ethylacetate (90:10) were afforded Gardenin-B (500 mg). Fractions (374-430) and Fractions (439-500) eluted with hexane: ethylacetate (85:15) yielded Gardenin-A (450mg). 5-Desmethylnobiletin (350mg) respectivily. Fractions (526-535) was subjected to reverse phase preparative HPLC (RP-C18, MeOH: H2O with 0.1% trifluoroacetic acid; 60:40, 3 mL/min) at 334 nm which yielded compound 4 Xanthomicrol (50 mg) (Retention time-12.5 minute). Fractions (577-582), eluted with hexane: ethylacetate (80:20) yielded Gardenin-D (150mg). Fractions (636-642), eluted with hexane: ethylacetate (80:20) afforded Gardenin-E
