Present study analyses the phytochemicals in some selected lichens of Seshachalam Biosphere Reserve, Andhra Pradesh. The lichen species are identified as Heterodermia diademata (Taylor) D.D. Awasthi, Parmotrema andinum (Müll. Arg.) Hale, P. grayanum (Hue) Hale, P. nilgherrense (Nyl.) Hale, P. praesorediosum (Nyl.) Hale, P. reticulatum (Taylor) M. Choisy, P. tinctorum (Despr. ex Nyl.) Hale, Parmelinella wallichiana (Taylor) Elix and Hale, Ramalina conduplicans Vain. and Usnea baileyi (Stirt.) Zahlbr. A total of 30 crude extracts in three different solvents such as 2-Propanol, Methanol and Water were prepared. The preliminary phytochemical screening revealed the occurrence of tannins, saponins, glycosides, proteins and triterpenoides in all the species while alkaloids, flavonoids, carbohydrates and steroids were found in some of the species. Aqueous extracts of all the species did not contain alkaloids, flavonoids, carbohydrates and steroids. Out of 10 species glycosides was present in 8 species, followed by presence of tannins, alkaloids and triterpenoides in 6 species. Flavonoids and proteins were found in 5 species and saponins and carbohydrates were found in 3 species only. Steroides were reported in P. reticulatum and P. andinum. Alkaloids, carbohydrates, flavonoids, glycosides, proteins, steroids, tannins and triterpenoides were reported in 2-propanol and methanolic extracts. Saponins were completely lacking in 2-propanol extracts of all the species. This is the first report with detailed phytochemicals analysis of lichens from Eastern Ghats of India.

Vismia genus is distributed mainly in tropical and subtropical regions of Central, South America and some areas of Africa. According to previous investigations, antioxidant potential of Vismia species might be related to anthrones, anthraquinones, flavonoids and phenol derivatives biosynthesized by these plants. The aim of present study is to evaluate the free radical scavenging capacity, total phenolic and flavonoids content as well as the qualitative phytochemical screening of methanol extracts obtained from Vismia macrophylla (VM) and Vismia baccifera (VB) collected in Táchira and Mérida state, Venezuela. Phytochemical screening of VB and VM methanolic extracts carried out using various chemical assays revealed an abundant presence of anthraquinones in both species analyzed. Glycosides were also present while flavones and dehydroflavones were observed abundantly in VB but moderated in VM. Triterpenes were also detected and steroids showed to be abundant in VM but moderate in VB. On the other hand, antioxidant capacity measured by the DPPH radical scavenging assay showed that VM possesses a stronger antioxidant activity than VB with IC50 5.50 µg/mL. Phenol and flavonoid assays also revealed that methanol extracts of both VM and VB contain high concentrations of these metabolites. A relationship between the antioxidant activity, total phenol and flavonoids content of the extracts analyzed was demonstrated in present investigation since those samples with higher phenolic concentrations showed likewise higher antioxidant activity.

Ticks limit the productivity of livestock through decreased production, reproduction, increased mortality, downgrading and rejection of hides and skin. A cross-sectional study was conducted to estimate the prevalence of tick infestation in ruminant while experimental study was used to evaluate the in-vitro acaricidal efficacy of methanolic extracts: Calpurnia aurea and Otostegia integrifolia and the phytochemicals present in those extracts at different concentrations (200, 100, 50, 25, 12.5 and 6.25 mg/ml) against Amblyomma variegatum. Adult immersion was used for the in-vitro acaricidal efficacy test and plant extracts were subjected to qualitative phytochemical screening for the presence or absence of secondary metabolites using standard procedures. Out of the 160 goats, 152 sheep and 121 cattle, 23 (14.4%), 44 (28.9%) and 28 (23.1%) were found to be positive for tick infestation, respectively. The incidence of tick infestation was significantly different (p<0.01) among ruminants. Five tick spp. were identified: A. variegatum, A. gemma, R. decoloratus, R. evertsi evertsi and R. pulchellus. Extract of C. aurea and O. integrifolia was found to contain alkaloids, saponins, phlobatannin, steroids, phenolic, flavonoids, glycosides and tannins. However, both plants were found negative for triterpens. Extracts of C. aurea and O. integrifolia at 200 and 100 mg/ml concentrations showed a significantly higher (p<0.05) acaricidal activities compared to other treatments at 24 hrs post exposure. Mortality of ticks was increased with the increased dosage (concentration) and exposure time after treatment. Extracts of C. aurea showed a significantly higher (p<0.05) tick mortality (52%) compared to those of O. integrifolia (27%). This is a promising finding to have alternative means of treatment and to substitute the use of synthetic drugs which have a wide spread drug resistance especially in developing countries like Ethiopia. Key words: Calpurnia aurea; in-vitro test; Otostegia integrifolia; Phytochemical screening; Tick infestation

Aim: To perform phytochemical screening of Plumbago zeylanica L. root extracts and assess the claim of its use in traditional management of erectile dysfunction in Uganda through evaluation of the aphrodisiac effect of its aqueous extracts in male Wistar rats. Study Design: This study employed both qualitative and quantitative research designs. Place and Duration of Study: All research work were performed at the Department of Biological Sciences, Gulu University, Gulu, Uganda between August 2019 and December 2019. Methodology: Classical phytochemical screening of aqueous and methanolic extracts of Plumbago zeylanica roots were performed following standard methods. Aqueous extracts were administered to Male Wistar rats and the effect of the extracts on the mounting and intromission frequencies were determined. Results: Glycosides, phenols, saponins, quinones, terpenoids and steroids were present in both methanolic and aqueous extracts. Alkaloids were present in methanolic extracts only while tannins and phlobatannins were only present in aqueous extracts. Flavonoids, coumarins and anthraquinones were not detected in both extracts. Aqueous root extracts of Plumbago zeylanica produced pro-sexual stimulatory effects in male rats when administered at 150, 300 and 450 mg/kg body weight. Conclusion: The results support the use of Plumbago zeylanicaroots by indigenous people in Uganda to increase libido, treat premature ejaculation and erectile dysfunction. The extracts had low sexual enhancement in sexually inexperienced male rats and therefore, further studies using experienced animal models are needed to better apprehend the prosexual effects of P. zeylanica roots. The toxicity of the extracts as well as structural elucidation and pharmacological evaluation of the responsible bioactive compounds merit further studies.

Objective: The objective of the study was to investigate in vitro antimicrobial activity against enterotoxigenic Escherichia coli and Bacillus subtilis and preliminary phytochemical screening of the leaves of Portulaca quadrifida (Linn.). Methods: The solvent extract such as petroleum ether, methanol, and water on the leaves of P. quadrifida (Linn) was prepared by Soxhlet extraction (continuous hot percolation method). These solvent extracts were screened for antimicrobial activity against enterotoxigenic E. coli and B. subtilis at various concentrations and were measured by observing zone of inhibition in mm by disc diffusion method (cup plate method). Results: The preliminary phytochemical screening revealed the flavonoids, fats, and oils in all extracts. Similarly, the presence of alkaloids and tannins was obtained in the petroleum ether and methanolic extracts, while the presence of glycosides was obtained in the methanolic and water extracts. Further, proteins and sterols were found in petroleum extracts. The results of antimicrobial activity shown that methanolic extracts of the plant leaf showed good antimicrobial activity and petroleum ether and water extract showed similar activity but less antimicrobial activity than methanolic extract. The antimicrobial activities of extracts were compared with standard antibiotic such as chloramphenicol. Conclusion: P. quadrifida (Linn.) has broad-spectrum antimicrobial activity and a potential source of new classes of antibiotics that could be useful for infectious disease chemotherapy and control. The phytochemical analysis of the crude extracts of this plant indicates the presence of major phytoconstituents which may have been responsible for the observed antimicrobial property.

Snakebite envenomation (SBE) is a life-threatening global public health problem affecting over 2.7 million persons annually, with a bigger burden lying in the developing world. Despite the successful management of SBE by antivenom therapy in conventional medicine, it is of low efficacy due to the diverse venom composition across snake types, which limits its usefulness. As a result, inhabitants of the sub-Sahara region, where SBE incidence is high, utilise medicinal plants as an alternative remedy for SBE. However, most plants have not been ethnobotanically documented and validated empirically and hence this study is needed. An ethnobotanical survey to document medicinal plants used to manage SBE in Migwani ward, Mwingi West Subcounty, Kitui County, was conducted between January and February, 2021. Ethnobotanical data were collected from 45 purposefully sampled respondents from Migwani ward using semistructured questionnaires, field walks, and oral interviews. In this study, 14 medicinal plants which are used to manage SBE were documented. Four plants with the highest Relative Frequency of Citation (RFC) (Entada leptostachya Harms-stem bark (0.58), Senna singueana-roots (0.53), Securidaca longipendunculata-roots (0.36), and Strychnos henningsii-stem bark (0.46)) were selected and extracted using water, methanol, and dichloromethane according to the standard procedures. Qualitative phytochemical analysis of the plant extracts and their cytotoxic effects on brine shrimp nauplii (brine shrimp lethality assay) was conducted according to the standard techniques. Qualitative phytochemical screening revealed the presence of anti-SBE-associated phytochemicals, such as alkaloids, saponins, tannins, phenols, and flavonoids, in the aqueous and methanolic extracts of the studied plant extracts. However, the tested phytochemicals were not detected in dichloromethane extracts of all the studied extracts. The anti-SBE effects of the documented plants could be attributable to these associated bioactive phytocompounds, which are synthesized by the studied plants and transfered to humans when consumed. Furthermore, the aqueous and methanolic extracts of Entada leptostachya and Senna singueana had high LC50 of >1000 µg/ml and were considered noncytotoxic. However, Securidaca longipendunculata had an LC50 of <1000 µg/ml and was considered slightly cytotoxic. Further empirical investigations to characterise the bioactive phytochemicals and their safety should be done.
