Objective
To evaluate the pharmacognostic characters of an important medicinal plant, Holoptelea integrifolia (H. integrifolia) Roxb.

Pharmacognostic evaluation of leaf and root bark of Holoptelea integrifolia Roxb.

Portulaca oleracea Linn, belongs to family Portulaceae and is a widely distributed weed. It has been used as a folk medicine in many countries as diuretics, febrifuge, antiseptic, antispasmodic and vermifuge. This paper deals with the microscopic study of leaf; stem and root of Portulaca oleracea, along with the physico-chemical and preliminary phytochemical analyses that were also studied.

Pharmacognostical studies of Portulaca oleracea Linn

Human skin works as a barrier against the adverse effects of environmental agents, including ultraviolet radiation (UVR). Exposure to UVR is associated with a variety of harmful effects on the skin, and it is one of the most common health concerns. Solar UVR constitutes the major etiological factor in the development of cutaneous malignancy. However, more than 90% of skin cancer cases could be avoided with appropriate preventive measures such as regular sunscreen use. Plants, constantly irradiated by sunlight, are able to synthesize specialized molecules to fight against UVR damage. Phenolic compounds, alkaloids and carotenoids constitute the major plant secondary metabolism compounds with relevant UVR protection activities. Hence, plants are an important source of molecules used to avoid UVR damage, reduce photoaging and prevent skin cancers and related illnesses. Due to its significance, we reviewed the main plant secondary metabolites related to UVR protection and its reported mechanisms. In addition, we summarized the research in Mexican plants related to UV protection. We presented the most studied Mexican plants and the photoprotective molecules found in them. Additionally, we analyzed the studies conducted to elucidate the mechanism of photoprotection of those molecules and their potential use as ingredients in sunscreen formulas.

Plant Secondary Metabolites against Skin Photodamage: Mexican Plants, a Potential Source of UV-Radiation Protectant Molecules

Ethnobotanical study of antilithic plants of Bhopal district.

Objective: The aim of the present study was to investigate the pharmacognostical and phytochemical characters of the medicinal plant Talinum triangulare (Portulacaceae), commonly known as waterleaf. The leaves of the shade-loving plant possess great therapeutic value in the traditional system of medicines but have not been fully exploited. Methods: Morphological and anatomical details of different parts of waterleaf were studied. The physico-chemical parameters, fluorescence analysis and quantitative estimation were determined for the crude drug. Preliminary phytochemical screening was carried out for different waterleaf extracts. Results: Physico-chemical properties such as loss on drying, total ash, acid insoluble ash and water soluble ash were calculated to be 10.643%, 28.070%, 0.067% and 7.789% (w/w) respectively. Water soluble extractive value (23.420% w/w) was more than the alcohol soluble extractive (10.080% w/w) of the drug. Preliminary phytochemical investigations of waterleaf extracts revealed the presence of various phyto-constituents such as like alkaloids, flavonoids, saponins, tannins, proteins and carbohydrates. Plant metabolites such as alkaloids (0.637 ± 0.191 mg/gm dry weight), flavonoids (0.225 ± 0.041 mg/gm dry weight), phenolics (0.319 ± 0.059 mg/gm dry weight), carbohydrates (1.295 ± 0.229 mg/gm dry weight), amino acids (2.033 ± 0.120 mg/gm dry weight) and proteins (1.218 ± 0.049 mg/gm dry weight) were quantitatively estimated. Conclusion: The evaluation of these characters will help future researchers in phytochemical as well as pharmacological analysis of this species.
