Background: Ochna kirkii Oliv. belongs to family Ochnaceae is commonly known as {\textquotedblleft}mickey mouse plants{\textquotedblright} in Asia, included in Jakarta. Objectives: This research was conducted to study the pharmacognosy and total phenolic content. Methods: The pharmacognosy study including the macroscopic, microscopic, fluorescence and phytochemical characteristic, which enable to identification of medicinal plant drug, as well as the total phenolic content using spectrophotometric method. Physicochemical parameters, like loss on drying, ash value, extractive values etc. were also determined following WHO guidelines. Results: Physicochemical standard quantified include total ash 5.15\% {\textpm} 0.4623, acid insoluble ash 0.32\% {\textpm} 0.2614, water soluble ash 10.72\% {\textpm} 0.2340, alcohol soluble extractive 12.8\% {\textpm} 1.3770, ether soluble extractive 7.30\% {\textpm} 1.8341, water content 5.76 \% {\textpm} 0.0050, loss on drying 6.91\% {\textpm} 1.6133. Preliminary phytochemical screening of the leaves showed the presence of flavonoids, tannins, phenols, saponins and triterpenoid. TLC profile of the O.kirkii leaves extracts (n-hexane, DCM, ethyl acetate and 70\% ethanol) showed 8, 6, 7 and 10 spots respectively; in different solvent system. The total phenolic content was 252.08 mg GAE/g{\textpm} 0.4430. Conclusions: The various macroscopic, microscopic, physical and phytochemical analysis of the O.kirkii leaf is useful in standardization for quality, purity and sample identification.

Background: Moringa oleifera leaves is one of the highly patronized herbs on the Ghanaian market. It is used for the treatment and prevention of several diseases. It is imperative that available and effective methods can be utilized to assess the quality of samples before being consumed. Objective: A study of the leaves was conducted to ascertain its physicochemical, phytochemical, heavy metal and microbiological content to develop a simple but acceptable criteria which could be useful in ensuring the quality of this crude drug. Materials and Methods: The qualitative and quantitative morphological features, physicochemical, phytochemical, microbial load and flouresent features of the leaves of M. oleifera were evaluated. Results: M. oleifera leaves were found to be glaborous with opposite leaflet, leaflet tripinnate, with a micronate apex and possessing an entire margin. Microscopy showed vein islets, rosette calcium oxalate crystals, polygonal epidermal cells and unicellular trichomes. The 50 \% ethanol soluble extractives of M. oleifera were highest, followed by the water and petroleum ether. Tannins, alkaloids, gylcosides, phenols, flavonoids, phenols, gums, and mucilage were present. Conclusion: The documented pharmacognostic features may be used as part of daily protocols to correctly identify and determine the quality of the the crude plant. The preliminary phytochemical, heavy metal and microbiological limits can be further used to ascertain the quality of raw materials of M. oleifera before they are used.

Background: Phyllanthus amarus is a medicinal plant used in the treatment of various ailments which include gonorrhoea, jaundice, diabetes, kidney diseases, bladder and intestinal infections, influenza, measles, viral infections, and tuberculosis. Tuberculosis treatment is faced with many challenges, resulting in a prolonged treatment regimen and potential treatment failure. There is a need to search for more favourable treatment options. Objective: This study aimed at investigating the pharmacognostic and mycobactericidal properties of P. amarus. Since toxicity could also be an issue, the mutagenic activity of this plant was also assessed. Materials and Methods: The macroscopic, microscopic, and physicochemical characteristics were assessed with reference to the Quality Control Methods for Herbal Material WHO (2011). The mycobactericidal activity was determined by the agar diffusion and broth dilution methods, while mutagenicity was investigated by the Ames test. Results: P. amarus contained tannins, flavonoids, glycosides, saponins and steroids. The 50\% ethanol extract exhibited activity against M. smegmatis at 100 mg/mL with an inhibitory zone of 2.0 cm. P. amarus had a minimum inhibitory concentration of 50 mg/mL while that of rifampin was 0.1 μg/mL. P. amarus showed weak mutagenicity at a concentration of 10 μg/mL. Conclusion: The documented pharmacognostic characteristics can be used for quality control of the crude plant material. The mycobactericidal activity also affirmed its folkloric use in the treatment of tuberculosis. The mycobactericidal activity can be further exploited for drug development.

Background: Cordia sebestena L. belongs to family Boraginaceae is commonly known as {\textquotedblleft}Geiger Tree{\textquotedblright} in Indonesia, it is generally found in Indonesia included Jakarta, and many other countries. Some researchers have revealed the presence of several pharmacology activities. Thus this study is an attempt to present an overview of pharmacognostic and phytochemical evaluation reported on this plant. Objective: In the present investigation, various pharmacognostic standards have been investigated to prove the authenticity of the plant for the claimed traditional uses. This will help in the identification of powder drug prior to using in medicine. Methods: Macroscopic, microscopic and physicochemical evaluation, of the drug was performed using standardized procedures as mentioned in the WHO and Indonesian Herb Pharmacopoeia guidelines.Thin layer chromatography profile was done using some different mobile phase system to the identification of the drug. Results: The physicochemical parameters such as moisture content, ethanol- and water-soluble extractive, total ash, acidinsoluble ash value, were determined. Phytochemical screening showed the presence of alkaloids, flavonoids, phenols, saponins, tannins, steroids, terpenoids in the ethanolic extracts of leaf of this plant. The TLC profile of n-hexane, dichloromethane and methanol extract were carried out 5, 7 and 2 spots respectively. Conclusion: The present study on pharmacognostical, physicochemical and phytochemical standards could be useful information for authentication and preparation monograph for C.sebestena.
