Content variability of bioactive secondary metabolites in Hypericum perforatum L
2021
Abstract St John’s Wort (Hypericum perforatum L.; Hypericaceae) is a perennial medicinal herb widespread and largely used in folk medicine inside the Mediterranean basin. Many bioactive compounds have been identified within its extracts. Under a pharmacological point of view, the most important of them belong to the chemical classes of naphthodianthrones, phloroglucinols and polyphenols. Many factors have been claimed responsible for the phytochemical variability in Hypericum perforatum, such as genotype, geographical origin, harvesting stage and age of the plants. Yet, when harvested plant material is addressed to the industry, the standardization of the active ingredients over cultivation…
Topical anti-inflammatory activity of some Asian medicinal plants used in dermatological disorders.
2001
The topical anti-inflammatory activity of extracts from Cassia angustifolia, Rheum palmatum, Coptis chinensis, Phellodendron amurense and Scutellaria baicalensis, plants used in traditional East Asian medicine against different skin disorders, was studied. Though in different degree, all the extracts significantly inhibited the edema induced by 12-O-tetradecanoylphorbol-13-acetate (TPA), in both single or multiple application, oxazolone, and arachidonic acid (AA). None of the extracts inhibited in vitro the activity of phospholipase A(2) (PLA(2)) from Naja naja.

Cytotoxic Activity and Composition of Petroleum Ether Extract from Magydaris tomentosa (Desf.) W. D. J. Koch (Apiaceae)
2015
The petroleum ether extract of Magydaris tomentosa flowers (Desf.) W. D. J. Koch has been analyzed by GC-MS. It is mainly constituted by furanocoumarins such as xanthotoxin, xanthotoxol, isopimpinellin, and bergaptene. Other coumarins such as 7-methoxy-8-(2-formyl-2-methylpropyl) coumarin and osthole also occurred. The antiproliferative activity of Magydaris tomentosa flower extract has been evaluated in vitro on murine monocye/macrophages (J774A.1), human melanoma (A375) and human breast cancer (MCF-7) tumor cell lines, showing a major activity against the latter.
Sedative Effect and Standardization Parameters of Herbal Medicinal Product Obtained from the Ocimum americanum L. Herb
2021
Abstract Sedative phytomedications continue to play an important role in the management of a considerable amount of anxiety symptoms because of the various side effects of synthetic sedatives and tranquilizers. However, developing new herbal drugs needs their appropriate quality control according to the relevant requirements. The aim of the study was to determine the sedative properties of the tinctures obtained from the American basil (Ocimum americanum L., Lamiaceae Martinov family) herb and to develop the standardization parameters for the promising herbal medicinal product. The open field test was used to evaluate the sedative effect of the prepared tinctures: (1) with the added of O. a…
Anti-inflammatory and analgesic activities of flavonoid and saponin fractions from Zizyphus lotus (L.) Lam.
2008
Abstract The effect of the flavonoid and saponin fractions from the leaves and root bark of Zizyphus lotus (200 mg/kg) was evaluated on carrageenan-induced paw edema in rats and on acetic acid-induced algesia in mice. In addition, two methanolic extracts from the plant (1 mg/ear) were tested on oxazolone-induced contact-delayed hypersensitivity (DTH) in mice. The effect of the different fractions was also evaluated in vitro on the nitrite production induced by lipopolysaccharide (LPS) in RAW 264.7 macrophages. The results showed that both the flavonoid and saponin fractions significantly inhibited paw edema, algesia, and nitrite production without affecting cell viability. Furthermore, the …
Ultraviolet Filters in Cosmetics
2018
Abstract UV filters are used in sunscreen cosmetics to protect skin from the sunlight. Nowadays, they are also incorporated into other daily-use cosmetics. However, many concerns about their safety have been raised, because they can be absorbed through the skin, further metabolized and eventually bioaccumulated and/or excreted. These percutaneous absorption processes may result in various adverse health effects (i.e., allergic contact dermatitis) and other more serious systemic effects, such as carcinogenic and oestrogenic activity. For this reason, UV filters as well as their maximum allowed concentrations have been regulated by the legislations in force. In this sense, analytical control …
