1. Effects of Light Quality and Chemical Elicitors on the Growth Parameters and Rosmarinic Acid Content of in vitro Cultures of Hyptis pectinata (L.) Poit.
Hyptis pectinata (L.) Poit is a folk medicinal species in Northeast Brazil. In this work, seedlings of H. pectinata were cultured in vitro under diverse light quality spectra and under the influence of two distinct chemical elicitors, salicylic acid and silver nitrate (SN), at concentrations of 30 and 60 μM. Growth parameters, biomass and rosmarinic acid (R

2. Chemical diversity and activity profiles of HIV-1 reverse transcriptase inhibitors from plants
Abstract Current challenges to antiretroviral therapy have opened new vistas in the search for novel drugs from natural products. This review focusses on plants as sources of inhibitors for human immunodeficiency virus type 1 (HIV-1) reverse transcriptase. Based on a systematic search of the literature, anti-HIV-1 reverse transcriptase activity was recorded

4. Effect of a rosmarinic acid supplemented hemodialysis fluid on inflammation of human vascular endothelial cells
Chronic systemic inflammation and repetitive damage of vascular endothelia by incompatible dialysis system are probable causes of cardiovascular disease in patients on dialysis. The present study aimed to assess in vitro biocompatibility and anti-inflammatory effect of hemodialysis fluid supplemented with rosmarinic acid (RA) using human umbilical vein endot

5. Evaluation of basil extract ( Ocimum basilicum L.) on oxidative, anti-genotoxic and anti-inflammatory effects in human leukocytes cell cultures exposed to challenging agents
ABSTRACT Ocimum is one of the most important genera of the Lamiaceae family. Several studies about basil and its popular use reveal many characteristics of the herb, including its use as antioxidant, anti-aging, anti-inflammatory, anti-carcinogenic, anti-microbial, and cardiovascular agents, among others. In this paper, we evaluated genotoxic, oxidative, and

6. Rosmarinic and Cinnamic Acid Derivatives of in vitro Tissue Culture of Plectranthus ornatus: Overproduction and Correlation with Antioxidant Activities
This work describes the tissue culture of Plectranthus ornatus Codd. (Lamiaceae) on Murashige and Skoog (MS) medium with naphthalene acetic acid (NAA) (1.0, 2.0 and 4.0 mg L-1) and 6-benzylaminopurine (BAP) (1.0, 2.0 and 4.0 mg L-1) as growth regulators to obtain the overproduction of rosmarinic acid. The content of rosmarinic acid and its biosynthetic precu

7. Optimization of ultrasound-assisted extraction of phenolic compounds, antioxidants and rosmarinic acid from perilla leaves using response surface methodology
Abstract Response surface methodology (RSM) was used to optimize ultrasound-assisted extraction (UAE) of functional components from perilla leaves. The factors investigated were ethanol concentration, extraction temperature, and extraction time. The results revealed that ethanol concentration had significant effects on all extraction parameters. Based on the

9. Evaluation of the orofacial antinociceptive profile of the ethyl acetate fraction and its major constituent, rosmarinic acid, from the leaves of Hyptis pectinata on rodents
ABSTRACT Hyptis pectinata (L.) Poit., Lamiaceae, popularly known as "sambacaitá," is an aromatic shrub largely grown in the Brazilian northeastern. We investigated the antinociceptive effects of the ethyl acetate fraction obtained from the leaves of H. pectinata and of its main constituent rosmarinic acid, on formalin (2%)-, glutamate (25 µM)- and capsaici

10. Evaluation of the antibacterial potential of Petroselinum crispum and Rosmarinus officinalis against bacteria that cause urinary tract infections
In this study we evaluated the antibacterial activity of the crude hydroalcoholic extracts, fractions, and compounds of two plant species, namely Rosmarinus officinalis and Petroselinum crispum, against the bacteria that cause urinary tract infection. The microdilution method was used for determination of the minimum inhibitory concentration (MIC) and minimu

11. HPLC/DAD determination of rosmarinic acid in Salvia officinalis: sample preparation optimization by factorial design
A sálvia (Salvia officinalis) contém altos teores de ácido rosmarínico (RA), uma substância bioativa, bem como outros polifenóis. RA é facilmente oxidável e pode sofrer degradação durante a preparação da amostra para análise. O objetivo deste trabalho foi desenvolver e validar um método analítico para a determinação do RA em sálvia, usando

12. Influence of rosmarinic acid and Salvia officinalis extracts on melanogenesis of B16F10 cells
Melanin is a photoprotective skin pigment, and pathologies characterized by hypo or hyperpigmentation are common. New compounds that regulate melanogenesis are, therefore, opportune, and many natural products with this property, as polyphenols, have been described. Salvia officinalis L., Lamiaceae, is a widely used food spice that contains high amounts of ph
