Methanol is a liquid that has the characteristics of being light, very easy to evaporate, colorless, flammable, toxic, and has a very distinctive odor like ethanol but lighter. The World Health Organization (WHO) globally states that 320,000 people die every year due to methanol poisoning in the age range of around 15 years to 29 years. Usually, symptoms of poisoning caused by methanol appear within 30 minutes to 2 hours. Based on the phenomenon that occurred, the author wanted to find out more about the effect of HBOT administration on the histopathological appearance of lung cells in mice intoxicated with methanol. This study used 30 male white wistar rat lung samples aged 2 to 3 months weighing around 150 grams to 250 grams, divided into three groups, namely the control group, treatment group I, and treatment group II. The control group was not given methanol treatment and hyperbaric oxygen therapy (HBOT). Treatment group I was given methanol for 14 days without hyperbaric oxygen therapy. Meanwhile, the treatment group was given methanol for 14 days and then given hyperbaric therapy for 10 days. The results show p\<0.0006, which means the data is significant and there are differences between groups. The results of this study can be concluded that administering hyperbaric oxygen therapy to rats intoxicated with methanol had a statistically significant improvement effect on the alveolar membrane, alveolar lumen, and connections between the alveoli.

Background: Ethnopharmacological relevance: Ruta chalepensis L For years, various portions of this plant have been utilized in traditional medicine to treat a number of illnesses, including nervous disorders, rheumatism, menstrual issues, fever, convulsions, mental disorders, dropsy, and neuralgia. Objection: In this study, we aim to characterize three flavonoids extracted from Ruta chalepensis L.\ Material and Methods: In this study, various concentrations (80\% and 100\%) of methanol and ethanol in water were used as solvents in the extraction of flavonoids (rutin, hesperidin, and quercetin) from Ruta chalepensis L. by using conventional extraction methods (reflex and maceration). Result: HPLC results confirm Using maceration with 80\% methanol was recommended for extracting flavonoids from Ruta chalepensis L. to obtain the highest yields, whereas reflex with 80\% ethanol showed a slight increase in quercetin amount. The phytochemical screening of Ruta chalepensis L. exhibited the presence of flavonoids. Conclusion: The highest amount of the three flavonoids was found in maceration with 80\% methanol.

Aim: Bioactive constituents of n-hexane and methanol fractions of Vernonia calvoana (VC) leaves were evaluated using Gas chromatography-Mass spectrometry. Method: The leaves were harvested, cleaned and air dried for 7 days. They were ground to yield 5kg weight powder which was macerated and extracted in 8000 mL of 80\% ethanol for 48 hours, yielding 310.3g (6.2\%) of crude extract after evaporation of the solvent. The paste (251.8g) was subjected to column chromatography over silica gel (mesh 60 \– 120\μm) and eluted with 1.5L of n-hexane and methanol respectively. The fractions were analyzed for bioactive constituents using Gas chromatography-Mass spectrometry (GC-MS) (30m x 0.25mm ID x 0.25\μm film thickness). Result: The results of GC-MS analysis showed the presences of twelve compounds with phytol (46.67\%), 8,11,14-eicosatrienoic acid (33.40\%), octadecanoic acid (11.25\%), pentadecane carboxylic acid (10.69\%), 9, 12, 15-octadecatrien-1-ol (8.12\%) and ethyl palmitate (7.68\%) in the n-hexane fraction, while methanol fraction was observed to have 14 compounds with oleic acid (33.40\%), hexadecanoic acid (12.49\%), 2-butanone (14.32\%), palmitadehyde (8.36\%), 11-octadecenoic acid (5.56\%), Z-4-nonadecen-1-ol-acetate (5.36\%) and limonene Oxide (4.37\%) as well as other compounds in trace concentrations. Conclusion: it may be concluded from the results that, extracts of Vernonia calvoana contain various bioactive components that may be exploited as a good source of new drug for pharmaceutical industries.

Objective: Gynura procumbens (Lour.) Merr is a well-known traditional herb and is widely used for traditional medicine by human. Previous clinical studies have shown the benefit effect of this leaves with inflammation, high blood pressure and others. This study aims to investigate the effect of methanol, ethanol, and ethyl acetate extracts of Gynura procumbens on U-87 cell line, human glioblastoma multiforme cell line. Methods: In the present study, effect of methanol, ethanol and ethyl acetate extracts on U-87 cell line was determined by MTT-based anti-proliferative assay and any significant changes to the cells towards apoptotic changes was observed under a light microscope. Results: The ethanol and methanol extracts of Gynura procumbens was found to have high anti-proliferative effect on U-87 cell line with IC50 less than 20\μg/ml. By comparing IC50 value, ethanol and methanol extracts of Gynura procumbens had high potential for anti-proliferative effect on U- 87 cell line. Therefore, ethanol and methanol extracts can be a potential anti-proliferative effect on U-87 cell line. Conclusion: To the best of our knowledge, this is the first study of exploring the effect of Gynura procumbens extracts using three different polarity (methanol, ethanol, ethyl acetate) effect on U-87 cell line, Human glioblastoma multiforme cells.
