Introduction: The study on guava fruit ethanol extract from Dukuhwaluh Village, Purwokerto, Central Java, Indonesia showed increased megakaryocytes and platelet numbers in thrombocytopenic mice model. The study of acute oral toxicity of the extract did not show toxic effects in the kidney and liver at doses of 2000 and 5000 mg/kg b.w. The aim of the study was to determine the profile and quantity of four metabolite compounds and total tannin and flavonoid in the extract. Materials and Method: gallic acid, ellagic acid, rutin and kaemferol in the extract were identified and quantified by using high-performance liquid chromatography (HPLC) method with column LiChroCART 250-4,6 RP 18E, isocratic mobile phases with the composition of mixture:0.1\% acetic acid, acetonitrile and methanol (40:50:10) respectively, and at temperature 300C. The total tannin and flavonoid were determined using the by spectrophotometry method, Fe(III) chloride and 1.10-phenanthroline at wavelength 510 nm for tannin and aluminium chloride and rutin at wavelength 422 nm for flavonoid, respectively. Results: Percentage of gallic acid, ellagic acid, rutin and kaempferol were 0.77\%, 1.37 \%, 0.41 \% and 0.35 \%, respectively. Total tannin and flavonoid contents were 1.20\% (TAE) and, 1.18\% (RE) respectively. Conclusion: The guava fruit ethanol extract contained gallic acid, ellagic acid, rutin, kaempferol, tannin and flavonoid.

Introduction: Quercus infectoria (QI) is medicinal plant well known to exhibit enormous therapeutic values. The main medicinal part of QI plant exists in its edible nutritious gall. This study aimed to determine the effects of extraction solvents on the overall phytochemical content, recovery of tannin and antioxidant activity of the QI galls. Methods: Two solvents of different polarity namely water and methanol, were used to extract bioactive compounds from the QI galls using soxhlet extraction technique. Phytochemical, TLC and HPLC assays were performed to detect and quantify the extracted compounds. DPPH assay was conducted to evaluate the antioxidant potential of the extracted compounds. Results: After 6 hours of extraction at respective solvent boiling points, methanol solvent successfully generated 1.8-fold higher crude yield (34.0\%) compared to water solvent (18.9\%). Phytochemical analysis revealed that both solvent extracts contained different secondary metabolites. The methanol extract was found richer in flavonoid, while the aqueous extract was found richer in phenol, tannin, gallotannin, triterpene and cardiac glycosides. Interestingly, we found that the major type of tannin presence in QI galls was gallotannin (hydrolysable tannin) instead of phlobatannin (non-hydrolysable tannin). The quantification results demonstrated that QI aqueous extract contained significantly higher gallotannin (75.0 μg/mL) compared to QI methanol extract (46.8 μg/mL). Furthermore, the aqueous extract also exhibited significant higher antioxidant activity compared to the methanol extract at concentration of 2 μg/mL. Conclusions: This study strongly support the utilization of water solvent for optimum gallotannin extraction from QI galls.

Results: Imperatorin and sinensetin were identified in fractions 5 to 9. The concentrations of sinensetin and imperatorin in Imperata cylindrica root methanol extract were of 32.348 and 37.014 mg/kg extract, respectively. The total tannin content was 1.06 \% (w/w) (TAE). Conclusion: Imperata cylindrica root methanol extract from Kendari had active phytoconstituents, namely sinensetin, imperatorin, and tannin.

Pterocarpus marsupium is an important therapeutic and medicinal plant belonging to family Fabaceae and commonly named as Indian Kino tree, Bijasal, Venga or Vijayasara. It is a huge deciduous plant and widely distributed in the Central, Western and Southern regions of India. Role of P. marsupium is found in Ayurveda, Homeopathic and Unani systems of medicine. It is a decent source of tannins and flavonoids hence, used as influential astringent, anodyne, cooling, regenerating agent and also used for the treatments of leprosy, leucoderma, toothache, fractures, diarrhea, passive hemorrhage, and dysentery, bruises and diabetes. It is also used to treat rheumatoid arthritis, gout, diabetic anemia, indigestion, asthma, cough, discoloration of hair, bronchitis, ophthalmic complications, elephantiasis and erysipelas. Researchers have been stated the presence of several phytoconstituents in P. marsupium and also their pharmacological activities. The current review aimed to define the phytochemical and pharmacological aspects of P. marsupium which will have been help in the researchers for further qualitative research.

Background: Terminalia ferdinandiana (Kakadu plum) is an endemic Australian plant with an extremely high antioxidant capacity. The fruit has long been used by the first Australians as a nutritional food and as a medicine and recent studies have reported its potent growth inhibitory activity against a broad panel of bacteria. Despite this, T. ferdinandiana extracts are yet to be tested for the ability to inhibit the growth of Bacillus anthracis. Materials and Methods: Solvent extracts were prepared using both the fruit and leaf of Kakadu plum. The ability to inhibit the growth of B. anthracis was investigated using a disc diffusion assay. Their MIC values were determined to quantify and compare their efficacies. Toxicity was determined using the Artemia franciscana nauplii bioassay. The most potent extracts were investigated using non-targeted GC-MS head space analysis (with screening against a compound database) for the identification and characterisation of individual components in the crude plant extracts. Results: Solvent extractions of T. ferdinandiana fruit and leaf displayed good growth inhibitory activity in the disc diffusion assay against B. anthracis. Fruit ethyl acetate and methanolic leaf extracts were particularly potent growth inhibitors, with MIC values of 451 and 377\μg/mL respectively. The fruit methanolic and chloroform extracts, as well as the aqueous leaf extracts also were good inhibitors of B. anthracis growth, albeit with lower efficacy (MIC values of 1800 and 1414 \μg/mL respectively).The aqueous fruit extract and leaf chloroform extracts had only low inhibitory activity. All other extracts were completely devoid of growth inhibitory activity. Furthermore, all of the extracts with growth inhibitory activity were nontoxic in the Artemia fransiscana bioassay, with LC50 values \>1000 \μg/mL. Non-biased GC-MS phytochemical analysis of the most active extracts (fruit ethyl acetate and methanolic leaf) putatively identified and highlighted several compounds that may contribute to the ability of these extracts to inhibit the growth of B. anthracis. Conclusions: The low toxicity of the T. ferdinandiana fruit ethyl acetate and methanolic leaf extracts, as well as their potent growth inhibitory bioactivity against B. anthracis, indicates their potential as medicinal agents in the treatment and prevention of anthrax.

Introduction: Total phenolic, flavonoid and tannin content of leaf and flower extract of Peltophorum pterocarpum (DC.) Backer ex K.Heyne was compared. Objective: To explore total phenolic, flavonoid and tannin content of both leaf and flower extracts of Peltophorum pterocarpum (DC) K Heyne. Method: Initially, collected fresh leaves and flower samples were shade dried and extracted with various solvents such as aqueous methanol (1:1), ethyl acetate, ethanol and aqueous. Qualitative analysis was performed for various phytochemical. Then the total phenolic content, total flavonoid content and total tannin content was estimated. Results: In preliminary phyto-chemical examination of various solvent extracts of both leaf and flowers of P. pterocarpum revealed that the presence of various phytochemicals such as phlobatannins, terpenoids, alkaloids, saponins, tannin, reducing sugars, phenols and steroids. In phtyochemical evaluation, when compare with all other solvents, Ethanolic extracts shows maximum extractive value. In case of ethyl acetate, it shows very low extractive value in all three phyto-chemicals. In phytochemical evaluation studies, total phenolic content of leaves shows highest in ethanolic extract (33.17 \± 4.72 mg/g) and lowest in ethyl acetate extract from flower (4.71 \± 0.07 mg/g), Similarly, flavonoid content of leaves shows highest in ethanolic extract (1.43 \± 0.01 mg/g) and lowest in aqueous extract of flower (0.23 \± 0.09 mg/g) but in case of tannin content, flower extracts shows higher tannin content in ethanolic extract (844.59 \± 10.38 mg/g) whereas lowest tannin content in leaf ethyl acetate extract (9.54 \± 6.98 mg/g). Conclusion: This is first report of comparative studies on total phenolic, flavonoid and tannin content of various solvent extracts both leaves and flowers from Peltophorum pterocarpum (DC) K Heyne.
