Assessment of two medicinal plants, Psidium guajava L. and Achillea millefolium L., in in vitro and in vivo assays Genet. Mol. Biol.
Teixeira,Rosangela de Oliveira; Camparoto,Marjori Leiva; Mantovani,Mário Sérgio; Vicentini,Veronica Elisa Pimenta.
The use of medicinal plants by the general population is an old and still widespread practice, which makes studies of their genotoxicity essential. Psidium guajava L. and Achillea millefolium L. are examples of plants commonly used in popular medicine. P. guajava L. is indicated for diarrhea and also as an antiseptic, while A. millefolium L. is indicated as an analgesic, antispasmodic, digestive, diuretic, antiseptic, astringent, emollient, wound healer and hemorrhoid medication. The aim of this study was to determine the effects of the infusions of these two plant species on chromosomes and the cell cycle. Leaves from the plants were used to prepare infusions, in the same manner as teas, but at two different concentrations. Allium cepa L. root-tip cells...

Effects of Maytenus ilicifolia Mart. and Bauhinia candicans Benth infusions on onion root-tip and rat bone-marrow cells Genet. Mol. Biol.
Camparoto,Marjori Leiva; Teixeira,Rosangela de Oliveira; Mantovani,Mário Sérgio; Vicentini,Veronica Elisa Pimenta.
Medicinal plants are widely used to treat various diseases, and in Brazil the plants Maytenus ilicifolia Mart. and Bauhinia candicans Benth are commonly used in popular medicine. However, there are a large number of compounds in plants which can produce alterations in genetic material, and this study was conducted to investigate any possible mutagenic and cytotoxic effects that M. ilicifolia and B. candicans infusions may have on the cell cycle and chromosomes. Infusions were prepared with in natura leaves to give two concentrations of infusions, one at the concentration normally used by the population in general and the other at 10 times this value (i.e. 3.5 and 35 mg/mL for M. ilicifolia and 0.465 and 4.65 mg/mL for B. candicans). Onion (Allium cepa L.)...

Parâmetros hematológicos de caprinos submetidos a diferentes tratamentos anti-helmíntico com plantas medicinais. Repositório Alice
PINHEIRO, R. R.; VIEIRA, L. da S.; CAVALCANTE, A. C. R.; DANTAS, L. B.; PEREIRA, M. de F..
Resumo: Foram avaliadas as alteraçoes hematógicas e os níveis séricos de proteína e albumina. em caprinos submetidos a diferentes tratamentos hanti-helm!nticos com plantas medicinais: Anona squamosa (folhas) e mormodica charantia L. (caule e folhas). Utilizaram-se 30 caprinos, machos, SRD, castrados, com idade entre sete e oito meses, naturalmente infectados cam nematódeos gastrintestinais, os quais foram distribuidos em trës grupos de 10 animais. 0 G-1 foi tratado cam 1g/kg de A. squamosa, o G-2 com 2g/kg de M. charantia, administradas sob a forma de suco, através de sonda gastro-esofágica e o G-3 (nao medicado). Coletou-se sangue antes e sete dias apos a medicaçao. Todos os grupos apresentaram reduçao significativa (P<0,05) nos valores do hematocrito,...

Possibility of using neural networks for moisture ratio prediction in dried potatoes by means of different drying methods and evaluating physicochemical properties CIGR Journal
Yaghoubi, Marjan; Askari, Bijan; Mokhtarian, Mohsen; Tavakolipour, Hamid; Elhami Rad, Amirhosein; Jafarpour, Afshin; Heidarian, Soodabeh.
Potato cubes were dried by different drying methods.  After the end of drying process, the experimental data were first fitted to the four well-known drying models.  The results indicated that the logarithmic and page models performed better compared with the other models.  Also, in this study neural networks were used in order to possibly predict dried potato moisture ratio (y), based on three input variables of drying time, drying temperature and different methods.  The results revealed that, logsig function based on 10 neurons in the first hidden layer could perform as the best goodness configuration for predicting the moisture ratio.  The comparison of the obtained results of ANNs and classical modeling indicated that, the neural networks have a higher...

Solid-liquid extraction of sorrel calyces with ethanol CIGR Journal
Olawale, Adegboyega Surajudeen.
  Ethanol extraction of three particle size distributions of sorrel (Hibiscus sabdariffa) calyces was investigated.  Extraction rate was found to increase with reduced particle size, increased temperature and solvent mass (solvent-feed ratio).  At 30oC, maximum yield or concentration was achieved with 50:1 solvent-feed ratio but no substantial increment occurred in these parameters beyond 20:1 ratio.  No degradation of the extract’s components occurred between 27oC and 70oC since linear relation between extraction yield and temperature was sustained.  Peleg equation and a variant of it gave the best fit for extraction kinetics.  The smallest calyx particles (

細胞分裂素與透氣性容器封口對丹參組培苗增殖與玻璃質化之影響 Taiwan Agricultural Research Institute
陳威臣; 蕭翌柱; 蔡新聲; 夏奇鈮; Uei-Chern Chen; Yih-Juh Shiau; Hsin-Sheng Tsay; Chi-Ni Hsia.
[[abstract]]本研究藉由改善細胞分裂素與培養容器透氣性,探討丹參(Salvia miltiorriza Bunge) 組培苗大量繁殖及抑制玻璃質化苗形成之方法。將丹參莖節培養於含有1 mg/l 氨基嘌 呤(benzyladenine, BA)與0.1 mg/l 奈乙酸(α-naphthaleneacetic acid, NAA)之全量MS (Murashige & Skoog)無基鹽類基本培養基中,可成功地誘導芽體形成及建立初代無菌丹 參培養苗。無菌苗培養於添加0.25 mg/l N-糠基腺嘌呤(N-furfuryladenine, kinetin)之全量 MS 基本培養基中,經6 週培養後每個培植體可獲得6.5 個芽體,優於0.5 mg/l kinetin 與0.5-1 mg/l BA 之處理,但所有處理之芽體均呈現玻璃質化。降低MS 鹽類與kinetin 濃度可部分改善玻璃質化苗的形成,其中以含有0.2 mg/l kinetin 之1/2MS 基本培養基 處理下,每個培植體可獲得5.6 苗較多,但仍有高達46.6%玻璃質化苗形成。利用透氣 性較高之藥包紙進行培養容器封口置換處理,可有效抑制丹參組培苗之玻璃質化,其中 以雙層鋁箔紙封口培養2 週,而後以三層藥包紙進行封口置換處理繼續培養4 週,每個 芽體可獲得4.8 株正常苗之表現最佳,不僅能完全抑制玻璃質化苗形成,且苗長可達約 4.78 cm。綜合本研究結果,建議丹參組培苗可利用含有0.2 mg/l kinetin 之1/2MS 基本 培養基進行組培苗增殖,同時配合上述培養方式之藥包紙進行培養容器封口置換處理, 不僅可建立丹參組培苗大量繁殖方式,更可完全抑制組培苗玻璃質化的產生。
