Abstract: Simira gardneriana (Rubiaceae) is a newly discovered tree species endemic to the Caatinga. For this reason, studies aimed at propagation, seed and seedlings analysis are essential for morphology, identification, classification, conservation. Our objective was characterize seeds, morpho-physiology of germination seedling establishment S. gardneriana. Therefore, we performed physical, b...
Background Cyclotides are disulfide-rich miniproteins with the unique structural features of a circular backbone and knotted arrangement of three conserved disulfide bonds. These features make them exceptionally stable and they have applications as plant defense (insecticidal) agents and stable drug frameworks. So far they have been found mainly in two plant families, including in every species...
The present study aims to evaluate the topical anti-inflammatory activity of "Pinda thailam", a herbal gel formulation containing aqueous extract of roots of Rubia cordifolia (Rubiaceae) and Hemidesmus indicus (Asclepiadaceae) which are known for their anti-inflammatory activity using the technique of carrageenin induced paw oedema in albino rats. The herbal gel formulation showed significant a...
The present study aimed at evaluating the antibacterial activity of methanol extract of Ruta chalapensis, L., (Rutaceae), Quercus infectoria Oliver., (Fagaceae) and Canthium parviflorum Lam., (Rubiaceae) against Staphylococcus aureus, Pseudomonas aeruginosa, Enterococcus faecalis, Klebsiella oxytocoa, Klebsiella pneumoniae and Proteus mirabilis. The experiment was carried out using disc diffusi...
Mitragyna genus, belongs to Rubiaceae family, distributed in Africa and Asia. Many species in Mitragyna genus have a history of use as a medicinal plant. Traditionally, it has been used to treat fever, malaria, diarrhea, muscle pain, inflammation and hypertension. Phytochemical research has showed that alkaloids, triterpenoids and flavonoids were main compounds in Mitragyna genus. Pharmacology ...
Background The genus Guettarda (Rubiaceae) comprises plants widely distributed in tropical areas [1]. Regarding the Guettarda sericea species, the literature shows that there is a lack of botanical and phytochemicals studies [2]. Thus, the present study aimed to evaluate the antibacterial effect of ethanol extract of leaves of G. sericea (EEFGS) on the growth of Streptococcus oralis ATCC 10557 ...
A new species of Spiradiclis (Rubiaceae) was found during our field trip to Guangxi, China, and is described here as Spiradiclislonganensis R. J. Wang. This species is readily distinguishable from other prostrate and decumbent species of the genus described previously by dense pubescence all over the plant, 5-20 small flowers per cymose, linear calyx lobes, and tubular corolla. The conservation...
The methanol extracts from five different plant families (Asteraceae, Euphorbiaceae, Melastomataceae, Rubiaceae, and Solanaceae) collected at Regional Natural Park Ucumarí (Colombia), were screened for their acetylcholinesterase inhibitory activity through the modified Ellman's spectrophotometric method. The best inhibitory activities on this study were shown by the extracts of Solanum leucocar...
The genus Psychotria (Rubiaceae) comprises more than 2000 species, mainly found in tropical and subtropical forests. Several studies have been conducted concerning their chemical compositions, showing that this genus is a potential source of alkaloids. At least 70 indole alkaloids have been identified from this genus so far. This review aimed to compile 13C-NMR data of alkaloids isolated from t...
Galium shinasii Yıldırım (Rubiaceae), is described as a new species from Malatya Province in eastern Anatolia, Turkey. The new species is morphologically related to Galium cornigerum Boiss. & Hausskn. Galium lasiocarpum and Galium sorgereae Ehrend. and Schönb. but clearly differs from them based on the morphological differences presented in the species description. In addition, the conservation...
