Abstract
In this study, our objective was to conduct a comprehensive phytochemical analysis, determine toxicity levels, and assess the antioxidant and antimicrobial properties of extracts derived from the leaves of Dipteryx alata Vogel, a native species of the Brazilian cerrado flora. Three distinct extracts were prepared utilizing assisted ultrasound and the Soxhlet apparatus, namely, Ultrasound Crude Extract (UCE), Soxhlet Crude Extract (SCE), and the Soxhlet Ethanol Extract (SEE). The phytochemical analysis revealed the presence of flavonoids, tannins, phytosterols, and saponins in all extracts. Additionally, alkaloids were specifically identified in the SCE and SEE extracts. In the analysis using LC-DAD, the compounds gallic acid, rutin, quercetin, luteolin and kampefrol were determined in higher concentrations in the SCE, followed by the SEE and UCE, respectively. The GC-MS analysis revealed the presence of campesterol, stigmasterol and β-sitosterol in all extracts, with UCE and SCE showing a higher concentration of β-sitosterol. SCE showed the highest concentration of all identified compounds. In the analysis of antioxidant activity by DPPH• and ABTS•+, SEE showed greater efficiency (IC50 = 2.98 ± 2.92 and 6.57 ± 0.89 μg/mL, respectively). In the toxicity test with Allium cepa, all extracts stimulated root growth at 50 g/mL; UCE and SEE stimulated root growth at 250 g/mL; and SEE inhibited root growth at 750 g/mL. In the Artemia salina toxicity, all extracts were non-toxic. Antibacterial activity was identified in the microorganisms S. aureus and S. mutans; however, the extracts did not show antifungal action against the strain of C. albicans. The extracts of D. alata have therapeutic potential for applicability in dentistry.

Abstract
Parkia platycephala is the only species of the genus Parkia that is endemic to the brazilian Cerrado and the tree symbol of the state of Tocantins, but there are still few studies regarding its bioprospecting. In this study, we aimed to investigate the phytochemical composition, toxicity and bioactivities of the bark and flower of Parkia platycephala. Hot sequential extractions (Soxhlet) were performed using methanol and hydroethanolic solution (70%), after degreasing the sample (hexane). The presence of flavonoids, tannins, steroids and alkaloids was detected in the preliminary screening. Trilinolein, (Z)-9-octadecenamide, 3-O-methyl-d-glucose were detected by Gas Chromatography coupled to Mass Spectrometry (GC-MS). In the Liquid Chromatography with Diode Array Detector (LC-PDA) analysis, it was detected exclusively ferulic acid (bark) and ellagic acid (flower). The ethanolic extract of the bark (IC50=10.69 ± 0.35 µgmL-1) has an antioxidant potential (DPPH• radical) higher than that of the rutin standard (IC50=15.85 ± 0.08 µgmL-1). All extracts showed excellent anticholinesterase potential (Ellman), with emphasis on the ethanol extract of the flower (IC50 =5.34 ± 0.12 µgmL-1). Regarding toxicity (Artemia salina), the methanolic extract of the bark and the ethanolic extract of the flower presented high and moderate levels, respectively. Such results limit the concentrations of biological activities in this study, however, the antioxidant and anticholinesterase indices fall short of toxicity. The results demonstrated promising antioxidant and anticholinesterase activities of both the bark and the flower of Parkia platycephala.

Abstract
This study evaluated to determine the phenolic and flavonoids contents, and antioxidant, anti-inflammatory, and antiproliferative activity of the hydromethanolic extracts of the leaves, pulp, and seeds of Annona cacans. The isolation and structural identification of the constituent acetogenin, phenolic acid, and flavonoids were also reported. Antioxidant capacity was determined by the 2,2-diphenyl-1-picrylhydrazyl (DPPH), ethylbenzothiazoline-6-sulfonic acid (ABTS), and β-carotene/linoleic acid methods. Cell proliferation was determined by spectrophotometric quantification of the cellular protein content using a sulforhodamine B assay. Anti-inflammatory activity was evaluated in paw edema model, to myeloperoxidase (MPO) activity induced by carrageenan in mice. Fractionation resulted in the isolation of one acetogenin (annoreticuin-9-one), two flavonoids (quercetin-3-O-β-glucoside-6-O-α-rhamnoside and kaempferol-3-O-β-glucoside), and one phenolic acid (p-coumaric acid). The pulp extract presented potent antioxidant activities by the DPPH (IC50 = 44.08 μg/mL) and ABTS (IC50 = 39.32 μg/mL) methods, as well as high contents of phenols (618.95 mg GA/g) and flavonoids (477.35 mg QE/g). The bioguided fractionation demonstrated that the ethyl acetate fraction of the pulp extract and annoreticuin-9-one showed potent antiproliferative activity against ovarian cancer (GI50 = 6.4 μg/mL). The anti-inflammatory activity demonstrated significant inhibition of edema compared to the control group in 2 and 4 h; in addition, the extracts inhibited the increase in MPO activity after 6 h, when compared to the DEX and control groups. For the first time, this study demonstrated antioxidant, anti-inflammatory, and antiproliferative activity, as well as compounds isolated, suggesting that A. cacans could also be potential sources for prevention of cancer and other diseases associated with oxidative stress.

Abstract
Mangifera indica is widely found in Brazil, and its leaves are used as an anti-inflammatory agent in folk medicine. The aim of this study is to perform composition analysis of essential oils from the M. indica varieties, espada (EOMIL1) and coração de boi (EOMIL2), and confirm their anti-inflammatory properties. Twenty-three volatile compounds were identified via gas chromatography-mass spectrometry (GC-MS) in two essential oils from the leaves. Paw edema and myeloperoxidase (MPO) activity were evaluated using the carrageenan-induced paw model, while leukocyte migration was analyzed using the pleurisy model. At oral doses of 100 and 300 mg/kg, the essential oils significantly reduced edema formation and the increase in MPO activity induced by carrageenan in rat paws. For a dose of 300 mg/kg EOMIL1, 62 ± 8% inhibition of edema was observed, while EOMIL2 led to 51 ± 7% inhibition of edema. At a dose of 100 mg/kg, the inhibition was 54 ± 9% for EOMIL1 and 37 ± 7% for EOMIL2. EOMIL1 and EOMIL2 significantly reduced MPO activity at doses of 100 mg/kg (47 ± 5 and 23 ± 8%, respectively) and 300 mg/kg (50 ± 9 and 31 ± 7%, respectively). In the pleurisy model, inhibitions were also observed for EOMIL1 and EOMIL2 in the leukocyte migration test. The results of the present study show that essential oils from M. indica differ in chemical composition and anti-inflammatory activity in rats.

Abstract
Campomanesia adamantium (Cambess.) O. Berg. is originally from Brazil. Its leaves and fruits have medicinal properties such as anti-inflammatory, antidiarrheal and antiseptic properties. However, the mutagenic potential of this species has been reported in few studies. This study describes the mutagenic/antimutagenic, splenic phagocytic, and apoptotic activities of C. adamantium hydroethanolic extract with or without cyclophosphamide in Swiss mice. The animals orally received the hydroethanolic extract at doses of 30, 100, or 300 mg/kg with or without 100 mg/kg cyclophosphamide. Mutagenesis was evaluated by performing the micronucleus assay after treatment for 24, 48, and 72 h, while splenic phagocytic and apoptotic effects were investigated after 72 h. Short-term exposure of 30 and 100 mg/kg extract induced mild clastogenic/aneugenic effects and increased splenic phagocytosis and apoptosis in the liver, spleen, and kidneys. When the extract was administered in combination with cyclophosphamide, micronucleus frequency and apoptosis reduced. Extract components might affect cyclophosphamide metabolism, which possibly leads to increased clearance of this chemotherapeutic agent. C. adamantium showed mutagenic activity and it may decrease the effectiveness of drugs with metabolic pathways similar to those associated with cyclophosphamide. Thus, caution should be exercised while consuming these extracts, especially when received in combination with other drugs.

Abstract
The chemical signature of social insects is very important for communication, and specific signs of each colony and its individuals are acquired throughout their development. This chemical signature can also be related to the composition of the materials employed during nest construction. Furthermore, the venom also contains important chemicals required for the maintenance of wasp colonies. Therefore, the objective of this study was to evaluate the chemical composition of the wasp Protopolybia exigua along its different development stages, including the nest substrate and the venom of adult worker at different ages. To achieve this, gas chromatography coupled to mass spectrometry was used. The results show that the chemical cuticular compounds present in different stages of development, and in the nest of P. exigua, are qualitatively similar, but quantitatively different, demonstrating that these compounds can be used as signals for the identification of co-specific individuals within the colonies. However, there was no significant variation in these compounds between different colonies, which may be related to the parental level between the colonies and due to them sharing the same resources. The non-polar compounds of the venom vary significantly according to the age of the workers, probably due to their different roles within the colony, and there was a clear increase in the complexity of the compounds as the wasps aged. Older wasps perform higher-risk activities, such as foraging, and therefore need to make more use of venom.

Abstract
Wasps belong to societies that are highly complex and diverse, especially considering social organization and parental care. They use chemicals in their daily communication, and act incisively in recognition of mates and non-nest mates, and can even identify individuals of different castes. In this study, cuticle composition was examined during the development of Polistes versicolor from the egg stage to adulthood, with the aim to assess changes in the chemical signature of the species, using gas chromatography. Linear alkanes and branched alkanes were identified that were important to distinguish the various developmental stages of P. versicolor. The variation in the linear alkanes and branched alkanes was quantitative, since most of them are present in all stages, with the exception of some linear alkanes that uniquely characterized the egg stage. At the egg stage, differences were predominant for linear alkanes C8, C24, C27, and C29. For the larval instars, there was a predominance of linear alkanes C8, C22 and C24 to C30. In the pre-pupae, pupae and adult stages, C8, C22, C24, and C26 to C30 showed a higher abundance during later developmental stages. The addition to branched alkanes increased their abundance from the egg (13.52%) to adult (22.96%) stages.

Abstract
The aim of this research was to investigate the antiproliferative and
anticholinesterase activities of 11 extracts from 5 Annonaceae species in
vitro. Antiproliferative activity was assessed using 10 human cancer cell
lines. Thin-layer chromatography and a microplate assay were used to screen the
extracts for acetylcholinesterase (AchE) inhibitors using Ellman's reagent. The
chemical compositions of the active extracts were investigated using high performance
liquid chromatography. Eleven extracts obtained from five Annonaceae plant species
were active and were particularly effective against the UA251, NCI-470 lung, HT-29,
NCI/ADR, and K-562 cell lines with growth inhibition (GI50) values of
0.04-0.06, 0.02-0.50, 0.01-0.12, 0.10-0.27, and 0.02-0.04 µg/mL, respectively. In
addition, the Annona crassiflora and A. coriacea
seed extracts were the most active among the tested extracts and the most effective
against the tumor cell lines, with GI50 values below 8.90 µg/mL. The
A. cacans extract displayed the lowest activity. Based on the
microplate assay, the percent AchE inhibition of the extracts ranged from 12 to 52%,
and the A. coriacea seed extract resulted in the greatest inhibition
(52%). Caffeic acid, sinapic acid, and rutin were present at higher concentrations in
the A. crassiflora seed samples. The A. coriacea
seeds contained ferulic and sinapic acid. Overall, the results indicated that
A. crassiflora and A. coriacea extracts have
antiproliferative and anticholinesterase properties, which opens up new possibilities
for alternative pharmacotherapy drugs.

Abstract
OBJECTIVE The essential oil from the leaves of Ocimum kilimandscharicum (EOOK), collected in Dourados-MS, was investigated for anticancer, anti-inflammatory and antioxidant activity and chemical composition. MATERIALS AND METHODS The essential oil was extracted by hydrodistillation, and the chemical composition was performed by gas chromatography-mass spectrometry. The essential oil was evaluated for free radical-scavenging activity using the DPPH assay and was tested in an anticancer assay against ten human cancer cell lines. The response parameter (GI50) was calculated for the cell lines tested. The anti-inflammatory activity was evaluated using carrageenan-induced pleurisy in mice. RESULTS The chemical composition showed 45 components with a predominance of monoterpenes, such as camphor (51.81%), 1,8 cineole (20.13%) and limonene (11.23%). The EOOK exhibited potent free radical-scavenging activity by the DPPH assay with a GI50 of 8.31 μg/ml. The major constituents, pure camphor (IC50=12.56 μg/ml) and mixture of the limonene: 1, 8 cineole (IC50=23.25 μg/ml) displayed a potent activity. The oral administration of EOOK (at 30 and 100 mg kg(-1)), as well as the pure camphor or a mixture of 1,8 cineole with limonene, significantly inhibited the carrageenan (Cg) induced pleurisy, reducing the migration of total leukocytes in mice by 82 ± 4% (30 mg kg(-1) of EOOK), 95 ± 4% (100 mg kg(-1) of EOOK), 83 ± 9% (camphor) and 80 ± 5% (mixture of 1,8 cineole:limonene 1:1). In vitro cytotoxicity screening against a human ovarian cancer cell line displayed high selectivity and potent anticancer activity with GI50=31.90 mg ml(-1). This work describes the anti-inflammatory, anticancer and antioxidant effects of EOOK for the first time. CONCLUSIONS The essential oil exhibited marked anti-inflammatory, antioxidant and anticancer effects, an effect that can be attributed the presence of majorital compounds, and the response profiles from chemical composition differed from other oils collected in different locales.
