TL;DR: In this article, the antimicrobial activity of the aqueous and ethanol extracts of nine Nigerian spices (Xylopia aethiopica, Myristia fragran, Aframomum sceptum, Garcina cola, Zingiber official, Piper guanine, Allium cepa, Vanilla fragran and Opium gratissimum) against Staphylococcus aureus, Klebsiella pneumoniae, Proteus vulgaris and Streptococcus faecalis was evaluated by determining the minimum inhibitory concentrations (MIC) of the
Abstract: The antimicrobial activity of the aqueous and ethanol extracts of nine Nigerian spices (Xylopia aethiopica, Myristia fragran, Aframomum sceptum, Garcina cola, Zingiber official, Piper guanine, Allium cepa, Vanilla fragran and Opium gratissimum) against Staphylococcus aureus, Klebsiella pneumoniae, Proteus vulgaris and Streptococcus faecalis was evaluated by determining the minimum inhibitory concentrations (MIC) of the extracts By and large, all the extracts possessed antimicrobial properties with the MIC of the extracts in the range of 5 mg/ml to 22 mg/ml The ethanol extract of V fragran (MIC=5 mg/ml ─ 10 mg/ml) was the most potent of all extracts while the least potent of the extract was M fragran (MIC=18 mg/ml ─ 22 mg/ml) Key word: Antimicrobial, extracts, aqueous, ethanol, spices, bacteria, minimum inhibitory concentrations

TL;DR: It was suggested that while both plants can serve as immune boosters and blood tonics, there is need for caution on excessive and prolonged consumption of P. amarus and X. aethiopica.
Abstract: A study on haematological effects of aqueous extracts from Phyllantus amarusand Xylopia aethiopica was investigated in albino rats. The extracts from both plants caused a dose-dependent decrease in...

TL;DR: In this paper, the Folin-Ciocalteu method was used to quantify the total phenolics in the aqueous extract of two spices, Xylopia aethiopica and Myristica argentea.
Abstract: The Folin-Ciocalteu method was used to quantify the total phenolics in the aqueous extract of two spices, Xylopia aethiopica and Myristica argentea A modified agar streak dilution method was used to assess the susceptibility of Escherichia coli and Staphylococcus aureus to the aqueous extracts of the spices The results showed that high levels of phenolics were present in the extracts The extracts also showed high-modest antimicrobial activity against the tested bacteria

TL;DR: Ethanolic and aqueous extracts of the fruits of Physalis angulata and X. aethiopica were tested on the second instar larvae of Anopheles gambiae at varying concentrations and the most effective was P. guineense in ethanol while the least active was J. curcas in water.
Abstract: Abtract: The efficacy of both the ethanolic and aqueous extracts of the fruits of Physalis angulata L. (Solanaceae); Xylopia aethiopica (Dunal) A. Rich (Annonaceae) and seeds of Piper guineense Schum and Thonn (Piperaceae); Jatropha curcas Linn. (Euphorbiaceae) were tested on the second instar larvae of Anopheles gambiae (L) at varying concentrations. With percentage mortality, P. guineense (83.33%) in ethanol was the most effective followed by its aqueous form (71.67%), P. angulata (36.94%) in ethanol, X. aethiopica (34.44%) in ethanol, J. curcas (33.06%) in ethanol, aqueous extracts of both P. angulata and X. aethiopica at 29.44% while the least active was J. curcas (20.56%) in water. On the basis of 24hrs LC values, P. guineense 50 (0.028 mg ml ) ethanolic extract acted most followed by its aqueous form (0.09 mg ml ), ethanolic extract of 11

TL;DR: The analgesic and anti-inflammatory properties of equimolar concentrations of the methanolic extracts of Alstonia Boneei, Ficus Elastica and Xylopia Aethiopica were investigated and MEFE significantly inhibited carrageenan induced inflammation and acetic acid induced writhing.
Abstract: The analgesic and anti-inflammatory properties of equimolar concentrations of the methanolic extracts of Alstonia Boneei (MEAB), Ficus Elastica ( MEFE) and Xylopia Aethiopica (MEXA) were investigated in 0.1% acetic acid induced Pain (Writhing) in Mice , and 0.4ml of 0. 1% carrageenan induced inflammation in rats as a model of acute inflammation and compared with Indomethacin. The MEAB and MEXA at concentrations used did not produce significant or marked inflammatory and analgesic effects while MEFE significantly (p <0.05) inhibited carrageenan induced inflammation and acetic acid induced writhing. Key Words: Analgesic, inflammation, Alstonia Boneei, Ficus Elastica and Xylopia Aethiopica, extracts

TL;DR: In this paper, the sterols quantification and identification were preformed by analysis of the unsaponifiable matter of the seed oil using GC/MS technique, the level of sterols estimated in the oil was 4.2 g/kg oil.
Abstract: Total lipids extracted from the seeds of X. aethiopica were found to be 10%. The oil was analyzed for fatty acids and sterols composition. Thirteen fatty acids were identified, with their methyl esters using GC/MS analytical method. The majority of fatty acids were unsaturated (72%). Oleic acid was the dominant unsaturated fatty acid (69.37%), while the saturated fatty acids represented about 27% of the total fatty acids present in oil from seeds, mainly palmatic acid (15.66%) and stearic acid (9.5 %). The sterols quantification and identification were preformed by analysis of the unsaponifiable matter of the seed oil using GC/MS technique. The level of sterols estimated in the oil was 4.2 g/kg oil. The main component was Sitosterol which represented about 58% of the total sterol content, followed by campesterol (23.5%) and ) -Avenasterol 5 (12.1%). Cholesterol was found at about 3% of total sterols.

TL;DR: Ten tropical plant species used locally in ethnomedicinal practices were evaluated for their biopesticidal potentials for the control of yam biodeterioration and Piper guineense treatment appeared to inhibit the sprouting of seedyams as compared with other treatments but without statistical difference.
Abstract: Ten tropical plant species used locally in ethnomedicinal practices were evaluated for their biopesticidal potentials for the control of yam biodeterioration in order to use them as substitute for synthetic pesticides in yam (Dioscorea rotundata Poir) production to control biodeterioration in storage. Seedyam setts slightly infested with rootknot nematodes (Meloidogyne spp. Goeldi, 1887; Chitwood, 1949) were treated with acetone extract of the plant materials by dipping for 24 hours at room temperature (30 ± 2C°). The treated seedyams were assessed after four (4) weeks, six (6) weeks and twelve (12) weeks for the effects of the plant extracts on inhibition of sprouting of seedyams, inducement of seedyam sprouting and biodeterioration, respectively. After four (4) weeks in storage, Piper guineense treatment appeared to inhibit the sprouting of seedyams (75%) as compared with other treatments but without statistical difference (p70.05). The extract of Anacardium occidentale treatments statistically (p induced seedyam sprouting best (83.3%); followed by Carica papaya (58.3%); Crotolaria retusa (48.10%) in relation to others, after six (6) weeks. Xylopia aethiopica (100%); Chromolaena odorata (100%); Piper guineense (100%); followed by Azadirachta indica (83.7%) controlled yam rot disease effectively (p < 0.05) after twelve (12) weeks in storage.
