The wastewater from the distillation of rose oils is discharged directly into the soil because it has a limited potential for future applications. The aim of the present study was to determine in vitro the chromatographic profile, redox-modulating capacity, and antineoplastic activity of wastewater obtained by distillation of essential oils from the Bulgarian Rosa alba L., Rosa damascena Mill., Rosa gallica L., and Rosa centifolia L. We applied UHPLC-HRMS for chromatographic analysis of rose wastewaters, studied their metal-chelating and Fe(III)-reducing ability, and performed MTT assay for the evaluation of cytotoxic potential against three tumorigenic (HEPG2—hepatocellular adenocarcinoma, A-375—malignant melanoma, A-431—non-melanoma epidermoid squamous skin carcinoma) and one non-tumorigenic human cell lines (HaCaT—immortalized keratinocytes). The median inhibitory concentrations (IC50) were calculated with nonlinear modeling using the MAPLE® platform. The potential of the wastewaters to induce apoptosis was also examined. Mono-, di-, and acylated glycosides of quercetin and kaempferol, ellagic acid and its derivatives as main chemical components, and gallic acid and its derivatives—such as catechin and epicatechin—were identified. The redox-modulating capacity of the samples (TPTZ test) showed that all four wastewaters exhibited the properties of excellent heavy metal cleaners, but did not exert very strong cytotoxic effects. The lowest IC50 rate was provided in wastewater from R. centifolia (34–35 µg/mL of gallic acid equivalents after a 72 h period for all cell lines). At 24 and 48 hours, the most resistant cell line was HEPG2, followed by HaCaT. After 72 h of exposure, the IC50 values were similar for tumor and normal cells. Still, R. damascena had a selectivity index over 2.0 regarding A-431 non-melanoma skin cancer cells, showing a good toxicological safety profile in addition to moderate activity—IC50 of 35 µg/mL polyphenols. The obtained results related to wastewaters acquired after the distillation of essential oils from the Bulgarian R. alba, R. damascena, R. gallica, and R. centifolia direct our attention to further studies for in-depth elucidation of their application as detoxifying agents under oxidative damage conditions in other experimental datasets.

Plants from the Rosacea family are rich in natural molecules with beneficial biological properties, and they are widely appreciated and used in the food industry, perfumery, and cosmetics. In this review, we are considering Rosa damascena Mill., Rosa alba L., Rosa centifolia L., and Rosa gallica L. as raw materials important for producing commercial products, analyzing and comparing the main biological activities of their essential oils, hydrolates, and extracts. A literature search was performed to find materials describing (i) botanical characteristics; (ii) the phytochemical profile; and (iii) biological properties of the essential oil sand extracts of these so called “old roses” that are cultivated in Bulgaria, Turkey, India, and the Middle East. The information used is from databases PubMed, Science Direct, and Google Scholar. Roses have beneficial healing properties due to their richness of beneficial components, the secondary metabolites as flavonoids (e.g., flavones, flavonols, anthocyanins), fragrant components (essential oils, e.g., monoterpenes, sesquiterpenes), and hydrolysable and condensed tannins. Rose essential oils and extracts with their therapeutic properties—as respiratory antiseptics, anti-inflammatories, mucolytics, expectorants, decongestants, and antioxidants—are able to act as symptomatic prophylactics and drugs, and in this way alleviate dramatic sufferings during severe diseases.

Pelargonium graveolens (Geranium) is a source of the finest quality of fragrance and its essential oils are used as antibacterial, and antifungal agents. The aim of the current research is to determine chemical constituents in the essential oil of P. graveolens by GC-MS and evaluate its antidiabetic activity via α-glucosidase inhibition assay. The chemical composition of P. graveolens essential oil was determined by GC/MS and its antidiabetic activity was assessed through inhibition of α-glucosidase enzyme in in-vitro models. GC-MS analysis determines 36 chemical components in the essential oil of P. graveolens leaves, and citronellyl isovalerate (10.41 %), menthol (9.61 %), linalool (8.63 %), p-menthone (6.31 %), and geranyl tiglate (4.99 %) were recorded as major constituents. The essential oil of P. graveolens leaves showed concentration dependant inhibition of α-glucosidase enzyme ranging from 28.13±1.41 to 74.24±2.53 µg/mL for concentration ranging from 31.25 to 1000 µg/mL. The IC50 values for of P. graveolens and acarbose were found as 93.72±4.76 and 80.4±2.17 µg/mL, respectively against the α-glucosidase enzyme. The study finding explores the chemical components of P. graveolens growing in the Iraqi Kurdistan region and scientifically supported its possible use in diabetic patients for controlling postprandial hyperglycemia.

Background: The current research was undertaken on dried fruits of Capparis moonii to screen its potential for immunomodulatory and cancer indications with identification of phytoconstituents by chromatographic techniques.Methods: Methanolic (MECN), hydro-methanolic (HMECN) and aqueous extracts (AQCN) of Capparis moonii were subjected to high performance thin layer chromatography (HPTLC) and high-performance liquid chromatography (HPLC) after studying the total phenolic and flavonoid content by using rutin and gallic acid as standards respectively as well as undertaking powder characteristics and preliminary phytochemical screening. Immunomodulatory activities covered were hemagglutination antibody titre and delayed-type hypersensitivity reaction with the aid of sheep red blood cells (0.5×109) as antigens.  The extracts were studied for antioxidant potential. Anticancer prospects were focusing on in vitro cell lines screening (MCF 7 and HCT 15) by Sulforhodamine B assay method and potato disc assay.Results: The total phenolic and flavonoid content of MECM, HMECM and AQCM fruits extracts were found to be 0.20, 0.11 and 0.47 mg of gallic acid/g and 78.3, 18.8 and 64.4 mg of rutin/g respectively. Rutin and quercetin were confirmed by HPTLC and HPLC showing well resolved peaks. IC50 values in antioxidant studies were found to be significant with all the extracts. Significant immunomodulatory effect was noticed at 200mg/kg in both models (high antibody titre levels and decrease paw volume after 48 h). Unsatisfactory results were observed with selected cell lines and disc assay.Conclusions: Thus, selected fruits may probably have immunomodulatory potential due to presence of flavonols (rutin and quercetin).

EucalyptusL. is traditionally used for many medicinal purposes. In particular, someEucalyptusspecies have currently shown cytotoxic properties. Local Brazilian communities have used leaves ofE. benthamiias a herbal remedy for various diseases, including cancer. Considering the lack of available data for supporting this cytotoxic effect, the goal of this paper was to study thein vitrocytotoxic potential of the essential oils from young and adult leaves ofE. benthamiiand some related terpenes (α-pinene, terpinen-4-ol, andγ-terpinene) on Jurkat, J774A.1 and HeLa cells lines. Regarding the cytotoxic activity based on MTT assay, the essential oils showed improved results thanα-pinene andγ-terpinene, particularly for Jurkat and HeLa cell lines. Terpinen-4-ol revealed a cytotoxic effect against Jurkat cells similar to that observed for volatile oils. The results of LDH activity indicated that cytotoxic activity of samples against Jurkat cells probably involved cell death by apoptosis. The decrease of cell DNA content was demonstrated due to inhibition of Jurkat cells proliferation by samples as a result of cytotoxicity. In general, the essential oils from young and adult leaves ofE. benthamiipresented cytotoxicity against the investigated tumor cell lines which confirms their antitumor potential.

Axenic shoot culture of Mentha spicata L. was established from young shoots of the plant naturally growing in the field. Large number of multiple shoots were observed on MS media supplemented with NAA (0.5ppm) and BAP (1ppm) within eight weeks of culture. Extensive root formation was observed on MS medium supplemented with 1 ppm NAA. Essential oils from both in vitro and in vivo samples showed l- carvone as a major constituent, however, the in vitro samples showed higher concentration of menthol than in vivo samples. <i>Nepal Journal of Science and Technology</i> Vol. 7, 2006

The chemical composition of the essential oils of two endemic plants of Turkey, Stachys rupestris Montbret et Aucher ex Benth. and Salvia heldreichiana Boiss. ex Benth., were obtained by hydrodistillation and studied by GC and GC–MS. In all, 46 compounds were identified, 22 for S. rupestris accounting for 94.6 % of the total oil and 30 for S. heldreichiana, accounting for 91.9 % of the total oil. The presence of diterpenoids (50.7%) characterized the oil from S. rupestris, while S. heldreichiana oil was rich in oxygenated sesquiterpenes (78.9%). The essential oils were evaluated for their in vitro potential cytotoxic activity on three human cancer cell lines. The oil of S. rupestris showed the higher antiproliferative activity against PC-3 and MCF-7 cancer cell lines.

Candidiasis therapy, especially for candidiasis caused by Candida non-albicans species, is limited by the relatively reduced number of antifungal drugs and the emergence of antifungal tolerance. This study evaluates the anticandidal activity of 41 plant-derived products against Candida species, in both planktonic and biofilm cells. This study also evaluates the toxicity and the therapeutic action of the most active compounds by using the Caenorhabditis elegans–Candida model. The planktonic cells were cultured with various concentrations of the tested agents. The Cupressus sempervirens, Citrus limon, and Litsea cubeba essential oils as well as gallic acid were the most active anticandidal compounds. Candida cell re-growth after treatment with these agents for 48 h demonstrated that the L. cubeba essential oil and gallic acid displayed fungistatic activity, whereas the C. limon and C. sempervirens essential oils exhibited fungicidal activity. The C. sempervirens essential oil was not toxic and increased the survival of C. elegans worms infected with C. glabrata or C. orthopsilosis. All the plant-derived products assayed at 250 µg/mL affected C. krusei biofilms. The tested plant-derived products proved to be potential therapeutic agents against Candida, especially Candida non-albicans species, and should be considered when developing new anticandidal agents.
