爵床科一新组合—菲律宾爵床

查阅模式标本后发现Hypoestes pulgarense Elmer的花单生或少数花聚生于叶腋内,并且花药两室,下方一室具矩.这些特征与枪刀药属(Hypoestes)聚伞花序及单室花药的特征不符,而与爵床属(Justicia)一致.因此提出一新组合--菲律宾爵床(Justicia pulgarensis(Elmer)C.M.Gao & Y.F.Deng).

The Justicia striata complex in tropical Africa (Justicia sect. Harnieria, Acanthaceae)

The Justicia striata complex is revised. Ten species are recognised, some of which are subdivided into subspecies and/or varieties. The morphological variation within the complex has been analysed by PC A and clustering methods. The complex is shown to be heterogeneous and the relationships with other parts of sect. Harnieria are discussed. Scatter diagrams, illustrations and distribution maps are also provided in addition to the enumeration of taxa.

Triterpenoidal glycosides from Justicia betonica

dFrom the aerial portion of Justicia betonica L., four triterpenoidal glycosides (justiciosides A-D) were isolated. Their structures were established through chemical and NMR spectroscopic analyses as olean-12-ene-1beta,3beta,11alpha,28-tetraol 28-O-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranoside, olean-12-ene-1beta,3beta,11alpha,28-tetraol 28-O-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranoside, 11alpha-methoxy-olean-12-ene-1beta,3beta,28-triol 28-O-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranoside, 11alpha-methoxy-olean-12-ene-1beta,3beta,28-triol 28-O-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranoside, respectively.     

Chemicals isolated from Justicia adhatoda Linn reduce fitness of the mosquito,Aedes aegypti L

Extracts from Justicia adhatoda L. (Acanthaceae) strongly reduced the fitness of the mosquito, Aedes aegypti Linn. The methanolic extracts inhibited several enzymes responsible for protecting insects from oxidative and other damage, including glutathione‐S‐transferase, superoxide dismutase, cytochrome P450, and α‐ and β‐esterases. They increased repellency (maximum repellency at 100 ppm) in host‐seeking adult females using the “arm‐in cage assay.” Histopathological examination showed the extracts led to serious midgut cell damage. Justicia adhatoda extracts led to reduced fecundity and oviposition of gravid females compared to controls. The extracts led to substantially reduced A. aegypti survival. We infer that the extracts have potential to reduce pathogen transmission by suppressing population growth of A. aegypti, and possibly other mosquito species.

Molecular modeling of cornulin (CRNN) for docking with phytocompounds from Justicia adhatoda L.

Cornulin (CRNN) is linked with tumour progression. Therefore, it is of interest to document data on the molecular modeling of cornulin (CRNN) for docking with phytocompounds (Pyrazinamide, Anisotine, Vasicinone, Vasicoline) from Justicia adhatoda L. Thus, we document the optimal binding features of these compounds with the cornulin model for further consideration.     

Antiulcerogenic effect of Justicia prostrata Gamble

Antiulcerogenic effect of the alcoholic (ALJP) and aqueous (AQJP) extracts of the whole plant of Justicia prostrata was studied in aspirin+pylorus ligated rat models and analysed for gastric volume, ulcer index, free and total acidity. Biochemical parameters like total proteins, total hexoses, hexosamine, fucose and sialic acid were also estimated. Both extracts (ALJP and AQJP) significantly reduced both the gastric volume and the acidity of gastric juice. It also significantly promoted gastric mucus secretion by increasing total carbohydrates and decreasing the protein concentration in aspirin+ pylorus ligated rats. The results suggest that both the extracts (ALJP and AQJP) possess antiulcer activity, whereas AQJP is more effective when compared with ALJP in aspirin+pylorus ligated rat models. The results were compared with the standard drug Rantidine, a H2 receptor antagonist.
