Pterospermum javanicum Jungh. (Bayur) is a species belongs to the Pterospermum genera (Malvaceae). Several species of Pterospermum had been reported for their ethnobotanical usage, but the studies about ethnobotany information of Bayur and its secondary metabolite compounds were still limited which have been published. This study aimed to observe the ethnobotanical usage of Bayur and to examine the phytochemical contents of the acetone extract of Bayur flower from West Lombok. The ethnobotany information of Bayur was obtained through interviews with local people and more information on the ethnobotanical records of P. javanicum (Bayur) was conducted by reviewing the scientific literature. The chemical compounds of Bayur flower were analysed by the GC-MS method. The results revealed that Bayur was used by the Sasak community  around Gunung Rinjani National Park West Lombok for various purposes, such as traditional medicines, beverages, rigging, and building material. The phytochemical analysis showed that the acetone extract of Bayur flower from West Lombok contained 38 identified chemical components, representing 93.78% of the total compounds. The major contents of them were Lupeyl acetate (10.68%), p-n-Amylphenol (8.16%), Lauric acid (7.31%), N-(Methyl-d2)- Aniline (5,82%), and Pentanal (5.07%). This report was the first publication about the phytochemical contents of Bayur flower. It is expected that this study gives further information on the potentials of Bayur, especially about its secondary metabolite to support and prove the truth of the cultural concept of society in utilizing Bayur as a medicinal plant.

Aims: The present study was conducted to determine the antioxidant activity and chemical components of Ficus abutilifolia. Miq. (Moraceae). Place and Duration of the Study: The study were performed at Department of chemistry, University of Ngaoundere, Cameroon, between July 2017 and September 2018. Methodology: Phytochemical study was carried out on all extracts of stem barks. Besides, the total phenols contents (TPC) using the Folin-Ciocalteu and the antioxidant activities using DPPH and FRAP methods were also evaluated. The isolation of compounds from the EtOAc extract was done using column and thin layer chromatographic techniques on silica gel. The structures of isolated constituents were elucidated using mass spectrometry, 1D and 2D-NMR techniques. Results: Phytochemical screening revealed that all the compounds tested were found to be present in the acetone extract; the hexane extract was the poorest in compounds. Acetone extract, DCM/MeOH (1:1) and MeOH extracts were found to be rich in phenols with TPC respectively (239. 849 ± 0.969), (232.676 ± 0.404) and (109.654 ± 0.724) mg EAG/100g EX. Except the n-hexane extract, all the others exhibit antioxidant activities, acetone extract being the most effective with an inhibitory concentration 50 (IC50) of (0.038 ± 0.002) mg/mL for the DPPH antiradical scavenging activity and (0,021 ± 0,002) mg/mL for FRAP. A new fatty acid named Pentacosyl henicosanoate (2) along with six known compounds Octatriacontane (1), β–sitosterol (3), a mixture of Lupeol acetate (4a), α-amyrin acetate (4b), β-amyrin acetate (4c) and Daucosterol (5) were isolated from the column chromatography of the ethyl acetate extract. Daucosterol (5) exhibited antiradical activity with an IC50 of (13.005 ± 0.005) mg/mL. Only Daucosterol (5) has exhibited antiradical activity with an IC50 of (13.005 ± 0.005) mg/mL among the isolated compounds. Conclusion: This study provides scientific evidence and support for the traditional uses of F. abutilifolia stem barks in the treatment of diseases associated with oxidative stress.

The use of traditional medicines holds a great promise as an easily available source as effective medicinal agents to cure a wide range of ailments among the people particularly in tropical developing countries like India. The present study investigates the qualitative and quantitative analysis of the major bioactive constituents of N. crenulata leaf extracts. The extractive values of aqueous, acetone and chloroform extracts were found to be 11.34, 4.24 and 6.06 respectively. Qualitative phytochemical analysis of these three solvent extracts confirm the presence of Alkaloids, Saponins, Flavonoids and Phenolic compounds in all the three extracts; however, these phytochemicals were more significant in aqueous extract. Quantitative analysis was carried out using TLC method by different solvent system. Amongst various solvent systems, Butanol: acetic acid: water (9: 0.9: 0.1 v/v/v) shows maximum resolution and number of spots produced at long UV (365 nm) and under iodine vapours. The TLC chromatograms constituted different coloured phytochemical compounds with different Rf values. It can be conveniently used to evaluate the quality of different area samples. This indicates that the leaves can be useful for treating different diseases because the therapeutic activity of a plant is due to the presence of particular class of compounds and thus can serve as potential sources of useful drugs in future.

In the Southern Pantanal, the hyacinth macaw (Anodorhynchus hyacinthinus), an endangered species, often chooses the manduvi tree (Sterculia apetala) as a nesting site, because of its physical properties. In addition, the chemical composition of the wood may also contribute to a nesting selection by the hyacinth macaws. The objective of this study was to determine the main chemical components of S. apetala bark for two seasons, and evaluate its fungicidal potential. Bark samples from S. apetala trees with and without nests of A. hyacinthinus were collected in January (wet season) and August (dry season) of 2012. The inhibition of mycelium growth (MGI) from tree samples with and without nests were assessed using a phytochemical analysis to evaluate their antifungal activity against Trichoderma sp. Phytochemical analysis confirmed the presence of phenolic compounds and flavonoids. In both seasons, samples obtained from nested trees had higher content of total phenols than those collected from non-nested trees. The average content of total flavonoids was higher in January for samples with nest and in August for samples without nest. All selected samples showed antifungal activity, and those with nest collected in August (peak of hyacinth macaw breeding) resulted in an MGI of 51.3%. Therefore, this percentage, related to the content of flavonoids and the presence of coumarins, may influence the reproductive success of hyacinth macaws and other species of birds, in this region. This is the first chemical study report with the stem bark of S. apetala.

Histopathological studies of the effects of chloroform and methanolic leaf extracts of Ilex kudingcha in Trypanosoma brucei infected albino wistar rats were investigated. The toxicity and phytochemical study were also carried out using standard protocol. T. brucei infected animals were administered orally with 200 and 400 mg/kg b.w. of the extracts and 3.5 mg/kg b.w. of the standard drug (diminazene aceturate). Results on acute toxicity studies (LD50) revealed no sign of lethality up to the dose of 5,000 mg/kg body weight but the liver and kidney histology of infected animals treated with 5,000 mg/kg b.w. of I. kudingcha extracts were observed to be hepatotoxic and nephrotoxic. The methanol extracts showed appreciably high in vivo anti-trypanosomal activities compared to the reference drug. Histological examination of the organs revealed serious pathological lesions in the liver of the infected animals without treatment (negative control). In the positive control animals (infected animals administered standard drug), mild multifocal aggregate of inflammatory leucocytes was observed. In the other experimental animals, no pathological lesion was observed in the liver, kidney, brain, and heart of infected animals treated with the methanolic extract and combined methanol and chloroform extracts. The effectiveness of the methanolic extract at reducing the lesions caused by the parasite is the same compared with the standard drug. Phytochemical analysis of the plant extracts showed that methanol extract contained appreciable high levels of alkaloids, saponin, tannins, phenol, and glycoside while flavonoid was not detected. Hence, the curative properties of methanolic extract of I. kudingcha as observed in the organs indicate its anti-trypanosomal properties but it should be consumed at minimal doses.
