Medicinal plants are one of the most important sources drugs used in pharmaceutical industry. Among traditional medicinal plants, Lippia gracilis Schauer (Verbenaceae) had been for several purposes Brazilian northeastern. In this study, leaf essential oil (EO) L. was prepared using hydrodistillation. Followed by GC–MS analysis, its composition characterized presence thymol (55.50%), as major constituent. The effects EO on cell proliferation and apoptosis induction were investigated HepG2...
Abstract Introduction The species Lantana camara is used in folk medicine. biological activities of this medicinal plant are attributable to the presence various derivatives triterpenoids and phenolic compounds present its preparations, indicating excellent economic potential. Objective In study, operational conditions ultrasound‐assisted extraction (UAE) microwave‐assisted (MAE) were optimized using Box–Behnken design improve total content (TPC) recovered hydroethanolic extracts L. leaves....
Herbal drugs have been used since ancient times to treat a wide range of diseases. Morinda citrifolia Linn (popularly known as "Noni") has in folk medicine by Polynesians for over 2,000 years. It is reported broad therapeutic effects, including effects against headache, fever, arthritis, gingivitis, respiratory disorders, infections, tuberculosis, and diabetes. The aim this study was investigate the antioxidant, anti-inflammatory, antinociceptive, antibacterial properties aqueous extract...
The antioxidant capacity by oxygen radical absorbance (ORAC)-FL method and antimicrobial activity using the broth microdilution of aporphinoids (liriodenine 1, anonaine 2 asimilobine 3) other alkaloids (reticuline 4 cleistopholine 5) isolated from bark Annona salzmannii A. DC. (Annonaceae) were evaluated. For activity, most active alkaloid was with ORAC value 2.09 relative trolox equivalents. some showed significant minimal inhibitory concentration (MIC) values in range 25-100 µg mL(-1)....
The essential oils from the leaves of Annona salzmannii and A. pickelii (Annonaceae) growing in Sergipe, northeastern region Brazil, were obtained by hydrodistillation using a Clevenger-type apparatus, analyzed GC/MS GC/FID. Thirty-four compounds identified oil twenty-seven that pickelii; sesquiterpenes predominated both oils. Bicyclogermacrene (20.3%), ( E)-caryophyllene (19.9%), δ-cadinene (15.3%), α-copaene (10.0%), allo-aromadendrene (5.7%) main components salzmannii, bicyclogermacrene...
Ruthenium-based compounds have gained great interest due to their potent cytotoxicity in cancer cells; however, much of potential applications remain unexplored. In this paper, we report the synthesis a novel ruthenium complex with xanthoxylin (RCX) and investigation its cellular molecular action human hepatocellular carcinoma HepG2 cells. We found that RCX exhibited cytotoxic effect panel cell lines monolayer cultures 3D model multicellular spheroids formed from This compound is detected at...
The production of Ocimum basilicum (basil) crop depends upon the availability all nutrients in soil solution. There is a lack information about its performance, at tropical conditions, using new fertilizer formulations, such as organo-mineral fertilizers, mainly under protected cultivation. These types fertilizers combine benefits main used agriculture (organic and chemical). Therefore, enhance health, provide balanced nutrient supply, improve yields quality. promote environmental...
► Leaves of Annona pickelii yielded terpenes, lignans, and isoquinoline alkaloids. Isolated compounds are reported for the first time. Isoquinoline alkaloids chemotaxonomic marker genus . Furofuranic type lignans predominant in leaves A. The NMR data nornuciferine ( 8 ) were revised.
The essential oil from the leaves of Annona vepretorun was obtained by hydrodistillation using a Clevenger-type apparatus and analyzed GC-MS GC-FID. Eighteen compounds representing 98.1% crude were identified. major identified bicyclogermacrene (43.7%), spathulenol (11.4%), alpha-felandrene (10.0%), alpha-pinene (7.1%), (E)-beta-ocimene (6.8%), germacrene D (5.8%), p-cymene (4.2%). trypanocidal activity against Trypanosoma cruzi epimastigote forms, as well as, antimicrobial antioxidant...
► Bark of Annona salzmannii yielded sesquiterpenes, steroids, and isoquinoline alkaloids. Isoquinoline alkaloids are the chemotaxonomic marker genus . The NMR data for reticuline ( 12 ) were revised. Selin-11-en-4 α -ol 3 is reported first time in
Caesalpinia pyramidalis Tul. (Fabaceae) is a plant found in the Northeast of Brazil that popularly used to treat inflammation. Acute pancreatitis (AP) an inflammatory disease for which abdominal pain relevant symptom. As there no specific therapy AP, we investigated effect ethanol extract from inner bark C. (EECp) on AP induced by common bile duct obstruction (CBDO) rats.AP was male Wistar rats (200-250 g, n=6-8) through laparotomy and subsequent CBDO. Animals were euthanized after 6 (G6h)...
Phytochemical investigation of the hexane extract from stem Xylopia laevigata led to isolation ent-kaurane diterpenoids, ent-kaur-16-en-19-oic acid, 4-epi-kaurenic ent-16β-hydroxy-17-acetoxy-kauran-19-al, ent-3β-hydroxy-kaur-16-en-19-oic and ent-16β,17-dihydroxy-kauran-19-oic as well spathulenol a mixture β-sitosterol, stigmasterol campesterol. The identification compounds was performed on basis spectrometric methods including GC-MS, IR, 1D 2D NMR. Potent larvicidal activity against Aedes...

Pelargonium graveolens l'Herit AND Lippia alba (Mill) N. E. Brown AGAINST Spodoptera frugiperda (J.E. Smith).Insecticidal activity of essential oils graveolens, and compounds geraniol, linalool, 1,8-cineole, limonene, carvone, citral Azamax ® were evaluated against frugiperda.Topical application assay showed oil P. has acute toxicity larvae (third instar) with LD 50 1.13 µg/mg per insect 90 2.56 insect.Three L. also exhibited insecticidal ranging from 1.20 to 1.56 2.60 3.75 insect.Geraniol,...
Essential oils from leaves of Xylopia frutescens (XFMJ) and two specimens laevigata (XLMC XLSI) were obtained by hydrodistillation using a Clevenger-type apparatus, analyzed GC-MS GC-FID.
