Four edible fruits from Vitis vinifera , Punica granatum , Citrus aurantium and Opuntia ficus indica from Algeria were analyzed in order to determine the total polyphenol, total flavonoid and flavonol contents using classical spectrophotometric methods. The antioxidant activity was established by three different single-electron-transfer-based assays (ABTS radical cation, FRAP, and DPPH assays) and one hydrogen-atom-transfer based assay (ORAC). Among the four fruits tested, the Vitis vinifera hydroalcoholic extract showed the highest antioxidant capacity with all methods. The results indicated that the antioxidant activity and the total phenolic content of the selected plants are significantly different ( p < 0.001 ).

“…Beside that, the amount of rosmarinic acid content is affected by the extraction procedure. On Mentha piperita, Salvia officinale and Orthosiphon stamineus has been reported contain rosmarinic acid 28,3 mg/g, 39,3 mg/g and 9,10 mg/g respectively 24,25 . Solvent, extraction method and pretreament of sample effect the capacity of rosmarinic acid extraction 25,26 .…”

Introduction: Rosmarinic acid has been utilized in traditional medicine as antioxidant, antiinflammation, anticancer and antibacterial. In order to control the herbal quality, validation of rosmarinic acid determination using high-performance liquid chromatography was developed. The objective of this report was to validate an HPLC technique for assessing rosmarinic acid levels. and application that method to determine rosmarinic acid in Rosmarinus officinalis, Symphytum officinale, Mentha piperita, Orthosiphon stamineus and Salvia officinale. Methods: The chromatographic separation was carried out on a reversed-phase C18 column with a mobile phase of 0,1% formic acid and acetonitrile and an isocratic elution at a flow rate of 0,5 mL/min. The wavelength for detection was set to 330 nm. The method has been validated for precision, accuracy, linearity, limit of detection, and limit of quantitation. Result: The concentration response of the detector was linear, with a coefficient of determination of 0.9933. The HPLC technique had an accuracy of 101,00 ± 6,43%. The precision was 6,36% when expressed as a coefficient of variation (CV). The highest level of rosmarinic acid was 214,86 ± 0,60 µg/mL in Rosmarinus officinalis extract. Conclusion: The HPLC method was valid to analyse rosmarinic acid level. The method can be applied in routine determination of rosmarinic acid of phytopharmaceutical products.

“…The leaves sample treated with P2O2 contained the highest rosmarinic acid content of 206.31 mg/g, while the lowest rosmarinic acid content was shown by sample treated with the P1O2 fertilizer, which was 144.43 mg/g. The content of rosmarinic acid in O. aristatus leaves is affected by the drying temperature used, the higher the drying temperature used, the lower the rosmarinic acid level (Abdullah et al, 2017). In a report by Abdullah et al (2017), the rosmarinic acid content in samples dried at 30°C (air dried), 40°C, and 50°C had average contents of 171.47 mg/g, 98.69 mg/g, 9.10 mg/g, respectively.…”

Cat’s whiskers plant (Orthosiphon aristatus B. Miq) is a medicinal plant containing various metabolites that act as antioxidants and anti-inflammatory, including rosmarinic acid. The domestic market demand for dry leaves was 20-40 tons and abroad it was 141-180 tons in the 1990-2005 period, while production from 2013 to 2017 decreased from 116 tons to 56 tons. Therefore, it is necessary to increase the cat's whiskers biomass production, one of which can be done through the engineering of growing media using organic fertilizers, including goat manure and microbes, e.g., Plant Growth Promoting Microorganisms (PGPM). This study aims to determine the optimal combination of PGPM – Goat Manure for biomass and the rosmarinic acid content in O. aristatus. The study was conducted using a 2-factor randomized block design (RBD) with 12 treatment combinations and 3 repetitions on cultivated land in the Tanjungsari area and analysis of the results was carried out in the SITH laboratory from October 2020 to March 2021. The rosmarinic acid content in the leaves ranged from 144.43 – 206.31 mg/g or 14.44 – 20.63%, with the highest content found in leaves treated with 3 ml/L PGPM and 86.2 g/plant goat manure fertilizer (P2O2).
