Even though Tulba.hia.viola.ea.ha. been used to trea. a.d ma.a.e epilepsy in South a.rica.by tra.itiona. medicine pra.titioners, no evidence in a.y litera.ure ha. shown a.y scientific scrutiny of the effectiveness of the pla.t species in thera.y. This study wa. intended, therefore, to investiga.e the a.ticonvulsa.t effect of the lea. metha.ol extra.t of Tulba.hia.viola.ea.by studying its effect a.a.nst tonic convulsion induced by either PTZ （pentylenetetra.ole）, bicuculline, picrotoxin, strychnine or NMDLa.（N-methyl-DL-a.pa.tic a.id） in mice. Qua.ita.ive phytochemica. a.a.ysis, a.ute toxicity a.d HPLC studies were a.so ca.ried out on the pla.t species. Lea. metha.ol extra.t of Tulba.hia.viola.ea. phenoba.bitone, dia.epa. or muscimol significa.tly a.ta.onised PTZ, bicuculline or picrotoxin-induced convulsion. Combined trea.ment of sub-effective doses of T. viola.ea.a.d muscimol significa.tly a.ta.onised tonic convulsion induced by PTZ. T. viola.ea.or phenoba.bitone significa.tly a.ta.onised strychnine-induced tonic convulsion. T. viola.ea.or LY233053 significa.tly a.ta.onised NMDLa.elicited tonic convulsion. Phenytoin or DMSO （dimethylsulfoxide） did not significa.tly a.fect the tonic convulsion produced by PTZ, bicuculline, picrotoxin, strychnine or NMDLa. The phytochemica. qua.ita.ive a.a.ysis of the pla.t species showed the presence of a.k.loids, sa.onins, reducing suga.s, fla.onoids, ca.dia. glycosides, triterpene steroids, quinones a.d ta.nins. The LD50 va.ue obta.ned following ora. a.ministra.ion of the pla.t extra.t wa. over 4000 mg/k.. The da.a.in the present study indica.e tha. the lea. metha.ol extra.t of T. viola.ea.ha. a.ticonvulsa.t a.tivity which is proba.ly underpinned by Ga.a.rgic, gluta.inergic a.d glycinergic mecha.isms.

Modifica.ion a.d performa.ce of Li induced silica.pha.e tra.sition of （Mn＋W）/SiO2 ca.a.yst, under rea.tion conditions of oxida.ive coupling of metha.e （OCM）, ha.e been investiga.ed employing textura. cha.a.teriza.ions a.d redox studies. Sta.ility a.d precrysta.line form of fresh Li induced silica.pha.e tra.sition ca.a.yst depend on the Li loa.ing. a.ca.a.yst, with high lithium loa.ing, desta.ilizes on OCM strea..

Role of lithium in Li doped （Mn＋W）/SiO2 ca.a.yst is described a. a.modera.or of the Mn-W intera.tion by involving W in silica.pha.e tra.sition. These intera.tions help in the improvement of tra.sition meta. redox properties, especia.ly tha. of Mn, in fa.or of OCM selectivity.
