This work was aimed at evaluating the probable toxicity of the methanol extract of the leaf, stem bark and root of Sacrocephalus latifolius on Artemia nauplii and fronds of Lemna minor. The powder samples of the three morphological parts were independently extracted with soxhlet extractor apparatus using 95% methanol and were dried with aid of ritory evaporator at 40ºC. The extracts were subjected to biological activities involving brine shrimp cytotoxicity and Lemna minor test for phytotoxicity at 10-100 μg /mL respectively. The experiment was done in replicates of three. Concentration-dependent cytotoxic and phytotoxic activities were recorded for the extracts. The results revealed that extract of the leaves demonstrated significant cytotoxic and phytotoxic activities over the other parts of the plant. At 10μg/mL, the three extracts recorded little or no cytotoxic activity. However, at the maximum concentration of 1000 μg /mL, cytotoxicities of 66.67 and 3.33% were recorded for extracts of the leaf and root bark respectively, while the extract of the stem bark showed no activity. However, the LC50 of the leaf was 467.74μg /mL, and that of the other extracts were observed to be ˃1000μg /mL. The results for phytotoxicity followed a similar trend with the extracts of the leaf and root bark recording 52.96 and 23.33 % phytotoxicities respectively at 1000 μg /mL. Having shown a higher activity over the other extracts, the leaf extract of S. latifolius could serves as a natural alternative pesticide and weedicide.

Abstract Zanthoxylum zanthoxyloides, syn. Fagara zanthoxyloides, is a tree growing in West Africa and is used in traditional medicine against a variety of diseases, including malaria. In the work reported here, root bark and stem bark extracts of this tree, as well as compounds isolated from the extracts, have been investigated for activity in vitro against chloroquine-sensitive and chloroquine-resistant strains of Plasmodium falciparum. In addition, toxicity against nauplii of the brine shrimp Artemia salina has been studied. Dichloromethane extracts of the root bark and stem bark, and a methanol extract of the stem bark, showed anti-parasitic activity towards chloroquine-sensitive as well as chloroquine-resistant P. falciparum, with IC50 values between 1 and 10 µg/mL. Among the isolated compounds, bis-dihydrochelerythrinyl ether, buesgenine, chelerythrine, γ-fagarine, skimmianine, and pellitorine were the most active, with IC50 values of less than 5 µg/mL. The dichloromethane extracts were toxic to brine shrimp nauplii, with LC50 values of less than 1 µg/mL. Methanol extracts were much less toxic (LC50 between 50 and 100 µg/mL). Among the isolated substances, bis-dihydrochelethrinyl ether was the most toxic (LC50 ca. 2 µg/mL).

Songi (Dillenia serrata) is a tree endemic to Southeast Sulawesi and its stem bark been used in folk medicine. Nonetheless, only a handful scientific knowledge regarding chemistry and biological activities has been investigated on the plant. The present study aimed to investigate the antioxidant and xanthine oxidase (XO) inhibitory activity of the stem bark of the plant. Methanol extract and organic fractions (petroleum ether, ethyl acetate, and methanol) of the dried powdered stem bark of songi were evaluated for phytochemical screening, total phenolic (TPC), total flavonoid contents (TFC), DPPH, FRAP, and XO in vitro assays. Flavonoids, tannins, terpenoids, steroids, and saponins present in the extract. TPC and TFC in extract were 59.2 mg GAE/g and 23.4 mg QE/g. The contents in organic fractions were in solvent-dependent manner (methanol>ethyl acetate>petroleum ether). Extract and fractions scavenged DPPH radicals (48.2–59.7%) at 100 μg/mL compared to ascorbic acid, trolox, and gallic acid (90.3–93.8%). FRAP values varied from 0.8–3.4 μg/μg equivalent trolox amount (quercetin and gallic acid were 25.7 dan 32.4 μg/μg, respectively). They also inhibited xanthine oxidase (15.3–50.3%) at 100 μg/mL (allopurinol, 98.2%). The study concluded the potential of methanol extract and organic fraction of the stem bark of songi, thus highlighted the prospect of songi to be used in herbal and drugs development from nature.

The purpose of this study was to determine the phytochemical profile of Zanthoxylum acanthopodium DC plant (Andaliman) and to know the extract part of plant ethanol Z acanthopodium DC as the best anticancer agent. Root basal samples, stem bark, leaves and fruit Z acanthopodium DC as much as 3 Kg, then dried up and smoothed. Fine samples of root, bark, leaves and fruit of Z acanthopodium DC were each weighed 450 gr and each sample was extracted using 5 L ethanol solvent. Root extract, bark, leaves and fruit Z anthoxylum acanthopodium DC obtained from extraction weighed as much as 1 g, then each of them in concentrations of 10, 100, and 1000 ppm. Cytotoxic tested using BSLT method with shrimp larvae of 10 tail, then determined LC50 by using relationship between probit and log of concentration. Each sample of fine roots, bark, leaves and fruit Z acanthropodium DC were weighed 3 grams. Then press the phytochemical profile. Phytochemical profile test results of each sample of acanthopodium DC Z showed the presence of alkaloids, flavonoids, tannins, terpenoids and saponins. The largest alkaloid content is found on the skin of stems and roots (++) with Papaya leaf comparison, the largest flavonoid content of bark (++) skin with peach flower compound, tannin leaf and tanug (+++) seedlings with Avocado seed comparator, and the largest Kandugan saponin on bark (+++) with the comparative Starfruit Wuluh. In the cytotoxic test results, each leaf extract of stem, leaves, roots and Z acanthopodium DC fruit has potential as an anticancer agent because the liberating LC50 in each sample is in the range 30-1000 ppm. The extract part of the stem bark has the greatest potential as an anticancer compared to fruits, leaves and roots. Because bark leaf extract has LC50 so that 57,677 ppm compared to root of 65,313 ppm, leaves of 77, 983 ppm, and fruit of 191,426 ppm. Usually root samples, stem bark, leaves and fruit Z acanthopodium DC can be used as an anticancer because of the content of flavonoids, saponins, alkaloids, tannins, and terpenoids.

Introduction: Capparis species (Capparaceae), also called caper, grow naturally in various regions of the world. Caper is a plant with medicinal and aromatic properties. Flower buds, root bark, and fruits of the plant are used in folk medicine due to their analgesic, wound healing, cell regeneration, tonic, and diuretic effects. Objective: The aim of this research was to evaluate in vitro (anti-urease, antioxidant, anticholinesterase) and in vivo (anti-inflammatory) biological activities of caper (C. ovata var. canescens). In addition, we aimed to identify its major phenolic compounds using high performance liquid chromatography with a photodiode array detector (HPLC-DAD) and confirmate them using quadrupole time-of-flight liquid chromatography with tandem mass spectrometry (Q-TOF-LC/MS). Also, we quantified the concentrations of several trace and major elements in plant samples using inductively coupled plasma-mass spectrometry (ICP-MS). Methods: The antioxidant, anti-urease and anticholinesterase activities of different plant extracts were evaluated using DPPH, FRAP, ABTS/TEAC, Indophenol and Ellman tests. The identification of phenolic compounds and trace element contents was performed using HPLC and Q-TOF-LC/MS and ICP-MS. Results: Soxhlet methanol extract exhibited the strongest anti-urease, antioxidant (ABTS/TEAC) and anticholinesterase activity. Soxhlet and maceration methanol extracts demonstrated significant anti-inflammatory effect in the altered edema size after the second hour of carrageenan injection. The active phenolic compounds in Soxhlet methanol extract were identified as rutin, quercetin-hexoside-hexoside, quercetin-3-O-hexoside and kaempferol-3-O-rutinoside. In addition, the average concentrations of vanadium, chromium, manganese, cobalt, copper, nickel, arsenic, selenium, zinc and lead were within the permissible limits defined by WHO for medicinal plants. However, it was found that the concentrations of cadmium and iron were higher than the maximum permissible limits. Conclusion: Our results suggest that although caper has a strong biological activity, it should be consumed carefully due to the excess amount of cadmium and iron elements it contains.

Essential oils of seven Musa spp.’s fruits namely, Musa acuminata colla ‘gros michel’ (PE), Musa acuminata colla ‘lakatan’ (PB), Musa acuminata colla ‘sucrier’ (PM), Musa acuminata × balbisiana ‘horn plantain’ (PT), Musa acuminata × balbisiana colla ‘saba’ (PN), Musa acuminata colla 'inarnibal' (PO) and Musa acuminata colla ‘red’ (PJ) were extracted by hydrodistillation method using Clevenger apparatus. The essential oils were analysed using GC-FID and identified using Kovat Indeces compared with published information. PE gave the highest yields of oils compared to the other species with yield of 0.43% and 0.28% for its peels and flesh, respectively. The most abundant groups present in most of the essential oils are ester and alcohol groups. The brine shrimp toxicity of PT, PM, PN and PO essential oils were tested and showed toxicity against brine shrimp in dose dependent manner. It can be concluded that the essential oils showed some biological activities which may be a potent medicine in curing tumor. This study implies that the presence of ester and alcohol groups are a good marker for the biological activities of plants. Further studies should focus on the potential of the essential oils of Musa spp. as an antitumor medicine.
