Abstract
Tinospora smilacina Benth. has been used in Australian indigenous medicine for the treatment of headache, rheumatoid arthritis and other inflammatory disorders. As part of an investigation into the anti-inflammatory potential of plants using an ethnopharmacological approach, the present study sought to evaluate the efficacy and safety of Tinospora smilacina. An ethanol extract of this plant was evaluated in vitro for anti-inflammatory activities on cyclooxygenase-1 (COX-1), cyclooxygenase-2 (COX-2), 5-lipoxygenase (5-LO) and phospholipase A(2) (PA(2)). The ethanol extract of Tinospora smilacina showed inhibitory activities on COX-1, COX-2, 5-LO and PA(2) with the IC(50) values of 63.5, 81.2, 92.1 and 30.5 micro g/mL respectively. Cytotoxic effect of the extracts of Tinospora smilacina was investigated in vitro using ATP-based luminescence assay and the results showed no cytotoxic effect on cell lines of skin fibroblasts (1BR3), human Caucasian hepatocyte carcinoma (Hep G2) and human Caucasian promyelocytic leukaemia (HL-60). This paper also describes the results of fractionations and bioassay guided chemical studies, suggesting that the anti-inflammatory activity is due to triterpene-fatty acid esters and free fatty acids.

Abstract
OBJECTIVE To study the major chemical constituents from the root tuber of Typhyonium flagelliforme. METHOD Compounds were separated and purified with silica gel column and preparative HPLC, and their structures were elucidated on the basis of spectroscopic evidence (UV, IR, MS, NMR and 2D NMR). RESULT Four compounds were identified as 1-O-beta-glucopyranosyl-2-[(2-hydroxyloctadecanoyl) amido]-4,8-octadecadiene-1,3-diol (1), coniferin (2), beta-sitosterol (3) and beta-daucosterol (4). CONCLUSION A cerebroside with significant antihepatotoxic activity and a phenylpropanoid glycoside were isolated from Typhyonium flagelliforme for the first time.

Abstract
In a continuation of our study of the Rutaceae, detailed chemical investigation on Micromelum minutum (Rutaceae) collected from Sepilok, Sabah, Malaysia gave four new coumarins. The structures of the coumarins have been fully characterised by spectroscopic methods as 3",4"-dihydrocapnolactone 1, 2',3'-epoxyisocapnolactone 2, 8-hydroxyisocapnolactone-2',3'-diol 3 and 8-hydroxy-3",4"-dihydrocapnolactone-2',3'-diol 4.

Abstract
Examination of the leaf exudate of the South African species Aloe littoralis by reversed-phase HPLC revealed the presence of two major metabolites. The identification of the two compounds without isolation was attempted by HPLC-NMR based on separation using a C18 column eluting with a deuterium oxide:acetonitrile solvent gradient and an inverse HPLC-NMR probe. For each compound, one-dimensional proton spectra, and two-dimensional homonuclear COSY and TOCSY, and heteronuclear HSQC and HMBC, spectra were collected. On the basis of the data obtained, the metabolites were characterised as 10-hydroxyaloin B and deacetyllittoraloin.

Abstract
Five alkaloids, four beta-indoloquinazoline and one furoquinoline, and four terpenoids, three limonoids and one modified sesquiterpene, have been obtained from the aerial parts of Bouchardatia neurococca (Rutaceae). Two of the alkaloids, 1,2-dihydroxyrutaecarpine and 2-(2-[3-formylindolyl])-(3H)-quinazolin-4-one (bouchardatine), and two of the limonoids, 23-oxo-21xi-hydroxy-21,23-dihydroveprisone (veprisonic acid) and 21-oxo-23xi-hydroxy-21,23-dihydroveprisone (isoveprisonic acid) are new. The pattern of secondary metabolites isolated is rather unusual in the Rutaceae and is reminiscent of Tetradium, a genus with which Bouchardatia has not previously been associated.

Abstract
Eight alkaloids and ten flavonoids isolated from four species of Boronia of the Rutaceae were screened against 17 clinical microbial strains. Of the test compounds, three acridone and one quinolone alkaloids and eight flavonoids were reported as novel natural products. Screening was carried out by the standard disc diffusion method. Of the tested compounds, six alkaloids and seven flavonoids including the novel products were active against six clinical strains. The active compounds showed mild to moderate activities against Bacillus subtilis, Staphylococcus aureus, Sarcina lutea, exterotoxigenic Escherichia coli, Salmonella typhi and Klebsiella sp. Of the active flavonoids, some exhibited fairly significant activity towards Staphylococcus aureus, Sarcina lutea, Salmonella typhi and Klebsiella sp. The flavonoids were observed to have higher spectrum and magnitude of activity than those of the alkaloids. A standard ampicillin disc was used to compare the results.

Abstract
Leaves, stem bark and root of Lonchocarpus xuul and Lonchocarpus yucatanensis were studied separately. A chalcone, 2',4-dimethoxy-6'-hydroxylonchocarpin (), and the flavones 5,4'-dihydroxy-3'-methoxy-(6:7)-2,2-dimethylpyranoflavone (2) and 5,4'-dimethoxy-(6:7)-2,2-dimethylpyrano-flavone (3), together with the known carpachromene (4), were isolated from the leaves of both species. Similarly, the previously reported flavans xuulanin (5) and 3beta-methoxyxuulanin (6), together with the novel 3beta,4beta,5-trimethoxy-4'-hydroxy-(6:7)-2,2-dimethylpyranoflavan (7), 3-hydroxy-4,5-dimethoxy-(6:7)-2,2-dimethyl-pyranoflavan (8), and 3,4-dihydroxy-5-methoxy-(6:7)-2,2-dimethylpyranoflavan (10), were isolated from the stem bark and root of both species. Finally, the known 2',4'-dihydroxy-3'-(3-methylbut-2-enyl) chalcone (13) was obtained from the root of L. xuul only. The structures of the various metabolites were established by interpretation of their spectroscopic data.

The last two have previously been synthesised but appear to be new natural products. A similar study of the aerial parts of G. thwaitesii led only to the isolation of the known flavonoids myricetin 4'-O-methyl ether-3-O-alpha-L-rhamnopyranoside (mearnsitrin) and myricetin-3-O-methyl ether (annulatin), together with the triterpenes friedelinol, friedelin and betulinic acid. All compounds were identified by spectroscopic analysis and, for known compounds, by comparison with published data.

Abstract
The methanol extract of Tabernaemontana penduliflora was found to appreciably inhibit [3H]-estradiol binding to estrogen receptors. Activity-guided fractionation led to the isolation of two known alkaloids, 10-hydroxycoronaridine (1) and its 10-O-methyl ether, voacangine (2). These alkaloids together with other related alkaloids were tested for their estrogenic activities. Among these molecules, 1 was found to be the most potent estrogen agonist and is distinctly more active than genistein.
