Pandanus sanderi Pandanaceae is characterized by longitudinal yellow and green stripes of the leaves. The stripes were cut separated and dried yielding 387.0 g of yellow and 898.4 g of green stripes. Both parts were ground and then added to nonaqueous solvents. The most significant yields were retrieved from the methanol extracts 19.54 g 5.05 and 58.27 g 6.48; yellow and green stripes respectively. The chloroform extracts from both stripes were fractionated using silica column chromatography hexane:acetone giving 12 and 16 fractions for the yellow and green stripes respectively. The precipitate from fraction 13 of the green stripes was collected. It showed a purple spot after spraying with cerric sulphate CHCI3:MeOH90:10; Rf 0.48. This compound 1 was analysed using spectroscopic methods. It was suggested that 1 was a terpenoid. Fractions 1416 possessed an orange spot after spraying with Dragendorff reagent 90:10 acetone:hexane; Rf 0.04. These fractions contained compound 2 an alkaloid. From fractions 5-7 of the yellow stripes a possible terpenoid 3 was collected 60:40 acetone:hexane; Rf 0.40. Meanwhile the aqueous methanolic extracts from both stripes were freeze-dried and subjected to a HPLC system Hypersil C-18; 4.6 x 150 mm; 5 -1m CH3CN:Hp 10 to 40; 12 min flow rate: 1 ml min-1. They gave similar chromatographic profiles which displayed five major peaks tR 8.05; 8.35; 8.61; 9.20; 11.09 min respectively. Further purification process is in progress. In summary all extracts contain phytochemicals which require complete identification in order to support the sustainability of this forest-cum-ornamental species.

Abstract

Pandanus sanderi Pandanaceae is characterized by longitudinal yellow and green stripes of the leaves. The stripes were cut separated and dried yielding 387.0 g of yellow and 898.4 g of green stripes. Both parts were ground and then added to nonaqueous solvents. The most significant yields were retrieved from the methanol extracts 19.54 g 5.05 and 58.27 g 6.48; yellow and green stripes respectively. The chloroform extracts from both stripes were fractionated using silica column chromatography hexane:acetone giving 12 and 16 fractions for the yellow and green stripes respectively. The precipitate from fraction 13 of the green stripes was collected. It showed a purple spot after spraying with cerric sulphate CHCI3:MeOH90:10; Rf 0.48. This compound 1 was analysed using spectroscopic methods. It was suggested that 1 was a terpenoid. Fractions 1416 possessed an orange spot after spraying with Dragendorff reagent 90:10 acetone:hexane; Rf 0.04. These fractions contained compound 2 an alkaloid. From fractions 5-7 of the yellow stripes a possible terpenoid 3 was collected 60:40 acetone:hexane; Rf 0.40. Meanwhile the aqueous methanolic extracts from both stripes were freeze-dried and subjected to a HPLC system Hypersil C-18; 4.6 x 150 mm; 5 -1m CH3CN:Hp 10 to 40; 12 min flow rate: 1 ml min-1. They gave similar chromatographic profiles which displayed five major peaks tR 8.05; 8.35; 8.61; 9.20; 11.09 min respectively. Further purification process is in progress. In summary all extracts contain phytochemicals which require complete identification in order to support the sustainability of this forest-cum-ornamental species.
