This family consists of 18 genera and 700 species of trees. In the Asia-Pacific region, about 20 species of Burseraceae are used to treat haemorrhoids, heal wounds and to treat skin infections. This plant has been used to heal wounds amongst the indigenous people of Malaysia. Furthermore no pharmacological and phytochemical studies have been reported on this species. This study was undertaken to screen the phytochemical and pharmacological aspects of this plant. Qualitative phytochemical properties of the crude extract was determined for the presence of tannins, flavonoids, alkaloids, saponins or sterols. Phytochemical analysis of Canarium patentinervium Miq. revealed presence of tannins and flavonoids in the ethanol extract of leaves and barks. Bioassay guided fractionation led to isolation of eight secondary metabolites by chromatography which were identified by NMR techniques. Two coumarins (scopoletin and scoparone), five phenols (cynaroside, hyperin, (+)-catechin, lioxin and syringic acid) and a norsesquiterpene with cyclohexenone ring (vomifoliol). The latter three compounds were isolated for the first time from the genus Canarium. The plant and the isolated compounds were then subjected to six biological assays comprising of antibacterial, antioxidant, anticancer, anti-inflammatory, anti-acetylcholinesterase and anti-parasitic activities. Infectious diseases remain the leading cause of death worldwide and bacteria have become more resistant to conventional antibiotic and the search for novel antimicrobial agents from medicinal plants has become crucial. Antibacterial test was done using disc diffusion method, minimum inhibitory concentration (MIC), minimum bactericidal v concentration (MBC) and death kinetic assay with ampicillin as the positive control. The ethanol extract of leaves and the hexane extract of bark displayed remarkable antibacterial activity against both Gram-positive bacteria and Gram-negative bacteria. All isolated compounds tested against S.aureus ATCC 11632 showed bacterial growth inhibition. Scopoletin, scoparone, hyperin, cynaroside and syringic acid had bactericidal effect <100 µg/ml. Only scopoletin had bactericidal effect and complete kill at MBC 50.00 µg/ml. Bacterial infections have been known to generate extensive formation of free radicals which is becoming increasingly recognized in the pathogenesis of the many human diseases. The role of free radicals and active oxygen is becoming increasingly recognized in the pathogenesis of the many human diseases, including cancer, neurodegenerative diseases, ageing, and atherosclerosis. Five various antioxidant assays with different mode of action [2, 2-diphenyl-1- picrylhydrazyl (DPPH) and 2, 2'-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), ferric reducing antioxidant power (FRAP), -carotene bleaching assay and superoxide dismutase (SOD) assay] were used to test the antioxidant scavenging abilities of this plant. Vitamin C (L-ascorbic acid), quercetin and trolox were used as positive controls. The ethanol extract of leaves and barks displayed superior antioxidant capacities. The EC50 values of the samples were consistently low in SET methods (ABTS, DPPH and FRAP) superior to standard as opposed to HAT method -carotene bleaching assay). Hyperin and (+)-catechin exhibited the most consistent free radical scavenging capability across the five antioxidant assay. Hyperin and (+)- catechin have significantly lower IC50 (0.75±0.03 µg/ml and 0.94±0.27 µg/ml respectively) compared to SOD enzyme (IC50 1.59±04 µg/ml). Scopoletin exhibited potent antioxidant activity compared to scoparone with significantly lower EC50 values in ABTS (IC50 1.08±0.03 µg/ml) compared to ascorbic acid (EC50 1.54±0.03 vi µg/ml) and lower values in FRAP assay (FRAP value 49.00±0.64 µg/ml) than quercetin (FRAP value 86.00±0.24 µg/ml) and ascorbic acid (FRAP value 347.00±0.23 µg/ml). -carotene bleaching activity with IC50 6.85±0.37 µg/ml. Infections and free radical generation are recognized in the pathogenesis of cancer. The ethanol and chloroform extract of barks showed significant anticancer activities with GI50 values of 34.40µg/ml and 23.44µg/ml. The most susceptible cell lines were found to be the breast cancer cell line, MDA 468. Scopoletin displayed potent anticancer effect against breast cancer cell line MDA 468 (GI50 0.09±0.25 µg/ml) and colorectal cancer cell line HT-29 (GI50 0.17±0.05 µg/ml), the latter being more significant that positive control doxorubicin (GI50 0.66±0.60 µg/ml). In recent years, roles have been identified for several inflammatory cells and for a large number of inflammatory mediators in important pathologies not previously linked to inflammation, such including atherosclerosis, as well as cancer. Recently, reports have appeared regarding so- cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2), but also 5-lipoxygenase (5-LOX). Chloroform extract of the barks had the lowest 5-LOX inhibition (IC50=29.53±0.0 (IC50= Ethanol extract of leaves had superior COX-1 inhibition (IC50 = 0.60±0.01µg/ml) compared to COX-2 inhibition (IC50 = 1.07±0.01 µg/ml), whereas the barks had superior COX-2 inhibition (IC50 = 9.39±0.03 µg/ml) as opposed to COX-1 (IC50 = 11.41±0.03 µg/ml). All isolated compounds exhibited significantly lower 5-LOX inhibition than NDGA. Scopoletin and scoparone were potent inhibitors of 5-LOX recording lowest IC50 values (IC50 0.34±0.01 µg/ml and 0.20±0.01 µg/ml respectively). However (+)- catechin had a more comprehensive anti-inflammatory activity with dual inhibition of vii 5-LOX (IC50 16.10±0.03 µg/ml) and COX (COX-1; IC50 12.08±0.02 µg/ml, COX-2; IC50 83.89±0.03 µg/ml). Syringic acid exhibited potent 5-LOX inhibition (IC50 1.38±0.03 µg/ml) and moderate COX-1 inhibition (IC50 34.89±0.02 µg/ml). Furthermore, oxidative and inflammatory processes are among the pathological features associated with the central evidence that acetyl cholinesterase (AChE) inhibitors have an anti-inflammatory role through action against free radicals and amyloid toxicity, as well as through decreasing release of cytokines from activated microglia in the brain and blood. Chloroform extract of the barks displayed the best activity (IC50 as opposed to positive control, galanthamine (IC50 = 0.74±0. extract of barks and leaves follow through with IC50 50 = . Only scopoletin, scoparone, vomifoliol and syringic acid showed AChE inhibition at IC50 <100 µg/ml. Syringic acid exhibited good AChE inhibition (IC50 29.53±0.19 µg/ml), lowest of all compounds tested. Choline is the precursor of phosphatidylcholine (PC), a main component of Leishmania promastigote membranes. Therefore, inhibition of choline formation may decrease Leishmania survival. This hypothesis can be tested by using inhibitors of the acetylcholinesterase enzyme (AChE), which catalyzes the hydrolysis of acetylcholine to choline and acetic acid, as leishmanicidal compounds. The hexane extract of leaves showed moderate antileshmanial activity with IC50 ethanol extracts showed activity against Giardia intestinalis and Entamoeba histolytica copoletin was tested against all three parasite amd it was more potent against Leishmania donovani (IC50 163.30±0.32 µg/ml) and MIC of >200 µg/ml for both Giardia intestinalis and Entamoeba histolytica. Six kinds of major biological effects were evident in the crude and viii compounds namely, antioxidant, antibacterial, anti-inflammatory, anti-AChE, anti- parasitic, and anticancer all of which were reported for the first time from this plant. Given the aforementioned evidence it is tempting to speculate that Canarium patentinervium Miq. represents an exciting scaffold from which to develop leads for treatment of inflammatory and oxidative stress related diseases.

Canarium album is a nature food, whose extract has been reported hepatoprotective, anti-inflammatory and antioxidant. In this study, we extracted polyphenol and flavonoid substances from Canarium album fruits, and demonstrated that they restrain lipid excessive accumulation induced by oleic acid in hepatocarci- noma cells. Moreover, polyphenol and flavonoid extracted fromCanarium album fruits facilitated phosphorylation of adenosine monophosphate activated protein kinase (AMPK) and regulated several lipid metabolism related genes expression, including fatty acid synthase (FAS), sterol regulatory element binding protein (SREBP)-1 and peroxisame proliferator activated receptor (PPAR)-α. Therefore, for the first time, we demonstrated thatCanarium album extract restrained lipid excessive accumulation by activating AMPK signaling pathway, downregulating SREBP-1 and FAS, upregulating PPAR-α in hepatocarcinoma cells, which may be of great significance for prevention and clinical treat- ment of lipid metabolism disorders. Keywords: Canarium album, polyphenol, flavonoid, hepatocarcinoma cells, lipid, AMPK Introduction plants including Juniperus lucayana [5], induc- es lipolysis in adipocytes of mice [6, 7].

Becerra,1 Kogi Noge,2 Sarai Olivier1 & D. Lawrence Venable3 1 Department of Biosphere 2, University of Arizona, Tucson, Arizona 85721, U.S.A. 2 Department of Biological Production, Akita Prefectural University, Akita 010-0195, Japan 3 Department of Ecology and Evolutionary Biology, University of Arizona, Tucson, Arizona 85721, U.S.A. Author for correspondence: Judith X. Becerra, [email protected] Abstract Bursera is one of the most diverse and abundant groups of trees and shrubs of the Mexican tropical dry forests. Its interaction with its specialist herbivores in the chrysomelid genus Blepharida, is one of the best-studied coevolutionary systems. Prior studies based on molecular phylogenies concluded that Bursera is a monophyletic genus. Recently, however, other molecular analyses have suggested that the genus might be paraphyletic, with the closely related Commiphora, nested within Bursera. If this is correct, then interpretations of coevolution results would have to be revised. Whether Bursera is or is not monophyletic also has implications for the age of Burseraceae, since previous dates were based on calibrations using Bursera fossils assuming that Bursera was paraphyletic. We performed a phylogenetic analysis of 76 species and varieties of Bursera, 51 species of Commiphora, and 13 outgroups using nuclear DNA data. We also reconstructed a phylogeny of the Burseraceae using 59 members of the family, 9 outgroups and nuclear and chloroplast sequence data. These analyses strongly confirm previous conclusions that this genus is monophyletic.

The structures of 1a and 1b were elucidated by extensive 1D and 2D NMR spectroscopy and confirmed by mass spectrometry. β-amyrin and α-amyrin were also obtained as the major constituents of the resin. Keywords: Canarium asperum , Burseraceae, asperol a, asperol b, β-amyrin, α-amyrin _____________________________________________________________________________________________ INTRODUCTION Canarium asperum subsp. asperum var. asperum Leenh. (Burseraceae) constitutes a highly polymorphous variety of the species that is endemic in the Malesian region, where it grows apparently well both in the primary and secondary forests or even in savannahs but mainly at low altitudes [1].
