heterophylla leaf powder can be used as an effective, low cost, and environmentally friendly biosorbent for removal of Pb+2 from aqueous solution. Phytoremediation / Leaf Biomass / Pb+2 Removal: Study showed A.Biosorbent / Chromium Removal: Study showed Araucaria leaves has the potential for a cheap and efficient biosorbent for toxic hexavalent chromium removal from natural and waste waters.Effect may be a synergism effect of the diterpene content. The in vitro cytotoxic effect of the resin extract was comparable to the reference drug Doxorubicin. Resin / Cytotoxicity / Breast and Colon Cancer Lines: Resin and isolated compounds showed variable cytotoxic activities against breast (MCF7) and colon (HCT116) cancer cell lines.Antiulcerogenic / Resin from Stem Exudate: Resin isolated from stem exudates showed anti-ulcerogenic activity against ethanol-induced stomach ulcers in Sprague Dawley rats using ranitidine as standard.No reported folkloric medicinal use in the Philippines. Main constituents of resin oil were α-copaene (29.9%), germacrene D (21.4%), γ-gurjunene (9.7%), δ-cadinene (7.1%), and sandaracopimara-8(14),15-diene (6.5%) as main constituents. heterophylla was dominated by 13- epi-dolabradiene (42.7%), beyerene (22.2%), rimuene (13.7%), and dolabradiene (3.9%). heterophylla yieldedĪlkaloids, flavanoids, sterols, cardiac glycosides, saponins, tannins, phenols, and terpenoids. Preliminary phytochemical screening of aqueous extract of leaves of A. Study of resin collected from the stem exudates yielded three labdane diterpenes, labda-8(17),14-diene, 13-epicupressic acid, and 13-O- acetyl-13-epicupressic acid. Classified as "vulnerable" in the IUCN Red List of Leaves are small, needle-like, crowded along the branches and branchlets.
Branches are longest at the base, gradually becoming shorted upwards. Norfolk pine is a cone-shaped evergreen tree growing 15 meters high, with lateral branches from the main trunk arranged in whorls. SPANISH: Pino de Norfolk, Pino de pisos, Araucaria de pisos.
