The phytochemical work on Pulsatilla wallichiana Ulbr. (Ranunculaceae Juss.) afforded a dilactone, anemonin (1) isolated, purified and identified by spectroscopic methods and comparison of their spectral data with the reported data. To the best of our knowledge, this compound was isolated for the first time from Pulsatilla wallichiana Ulbr. Moreover, the aqueous (aq.) methanolic extract of the whole plant sample of Pulsatilla wallichiana Ulbr. (PWW) and the methanolic extract of the whole plant sample of Physochlaina praealta (Decne.) Miers (Solanaceae Juss.; PPM) were also investigated for several biological activities including antifungal, antiinflammatory, anticancer (Rh30, Hela, 3T3), cytotoxic, phytotoxic, brine shrimp lethality and insecticidal activities. PWW showed insignificant antifungal while higher anti-inflammatory activity as compared to PPM. In anticancer activity, PWW showed a concentration dependent effect on Rh30 cell viability while both samples exhibited moderate phytotoxic activity.

The whole plant material of Corydalis adiantifolia Hook.f. andamp; Thomson was investigated for biological activities e.g. antifungal, antibacterial, insecticidal, cytotoxic, anticancer and phytotoxic activities and preliminary phytochemical screening. The methanol extract and dichloromethane fraction of the plant species exhibited 5% inhibition each against the fungus Aspergillus flavus. The methanol extract and water and dichloromethane fractions exhibited non-significant antibacterial activity and they showed inhibition against Hela cell lines and insignificant insecticidal activity. To understand the bioactive profile of C. adiantifolia, phytochemical screening approach is considered effective. The samples including methanol extract and n-hexane, dichloromethane, ethyl acetate and water fractions were subjected to qualitative phytochemical screening for the presence of various phytochemicals i.e. alkaloids, flavonoids, saponins, diterprenes, triterpenoids, anthraquinones, anthranol glycosides, reducing sugars and phenols. The results exhibited the efficacy of methanol extract showing the presence of more phytochemicals in comparison to the fractions of C. adiantifolia. Moreover, as a result of phytochemical isolation, 8-acetonyldihydrosanguinarine (1), β-sitosterol (2) and β-sitosterol-β-D-glucoside (3) were isolated, purified, and characterized by spectroscopic methods. To the best of our knowledge, all this study was carried out for the first time on C. adiantifolia.

The detailed investigation of a methanolic extract of aerial parts of Achillea pannonica SCHEELE. within a chemotaxonomic study led to the isolation of 6 flavonoid glycosides. Besides rutin, apigenin-7-O-glucopyranoside, luteolin-7-O-glucopyranoside, apigenin-7-O-rutinoside and acacetin-7-O-rutinoside, an unusual flavondiglucoside was isolated. Its structure was established by UV, 1HNMR and 13C NMR spectroscopic methods including 2D-NMR techniques and ESI-MS as luteolin-7,4′-O-β-diglucoside. This substance is reported for the first time in the genus Achillea. Chemotaxonomic aspects are discussed briefly

Chamaemelum fuscatum (Brot.) Vasc. is a south west Iberian chamomile that has been traditionally used as folk medicine in its natural distribution area but currently it is underestimated regarding its biological activities. For this reason, it is proposed in this paper to get insight into the scientific validation of the traditional knowledge of this plant with the aim of taking advantage of its anti-inflammatory, gastroprotective and antinociceptive activities, among others. To this aim, the chemical composition of the essential oil from the whole plant, the flowers and the green parts of this plant has been evaluated by gas chromatography–mass spectrometry (GC–MS). Plant materials were collected in Badajoz (Spain). A total of 61 components including monoterpenoids, sesquiterpenoids and aliphatic esters were identified. (E)-2-Methyl-2-butenyl methacrylate (27.57%–18.53%) and 2-methylallyl isobutyrate (9.79%–7.51%) were the most abundant compounds in the essential oils of flowers and of the whole plant, whereas α-curcumene, trans-pinocarveol, α-bergamotene and pinocarvone were the major terpenoids irrespective of the plant part considered. Certain compounds showing a relative high abundance as isobutyl methacrylate, isoamyl butyrate, α-bergamotene and pinocarvone were identified for the first time in this species. Finally, we have reviewed the bioactivity of several compounds to relate the ethnobotanical use of this plant in Spain with its volatile profile. This work is a preliminary contribution to reinforce the use to this Mediterranean endemic plant as a natural source of bioactives.

Bangladesh possesses a rich flora of medicinal plant. Out of the estimated 5000 species of phanerogams and pteridophytes growing in this country, more than a thousand are regarded as having medicinal properties. The aim of this study was to evaluate the in vitro antimicrobial activity and brine shrimp lethality of the whole plant extracts of Spilanthes paniculata, a plant belonging to the family Asteraceae. The crude extract, n-Hexane, chloroform and ethyl acetate soluble fraction of crude extract showed significant to moderate antimicrobial activity against three Gram positive and three Gram negative microorganisms. The zones of inhibition produced by the crude extract (methanolic extract), n-hexane, choloform and ethyl acetate soluble fractions were found to be 14.89 mm-19.40 mm, 14 mm-19.40 mm, 10.66 mm-13.50 mm and 9.50 mm-13.26 mm, consecutively at a concentration of 30 µg/disc. N-Hexane, chloroform and ethyl acetate soluble fractions of methanolic extract of Spilanthes paniculata were screened for antitumor properties using brine shrimp lethality bioassay. From the results of the brine shrimp lethality bioassay, it can be well predicted that n-hexane, chloroform and ethyl acetate soluble fractions of methanolic extract possess mild cytotoxicity on shrimp naupalii. The median lethal concentration (LC50, the concentration at which 50% mortality of brine shrimp nauplii occurred) of n-hexane, chloroform and ethyl acetate were 48.978 mg/ml, 92.61 mg/ml and 216.770 mg/ml, respectively, comparison with positive control vincristine sulphate with 0.839 mg/ml.

The chloroform soluble fraction of the methanolic extract of the aerial parts of Tanacetum santolinoides afforded six sesquiterpene lactones. Tanacetolide A (1) was isolated for the first time from a natural source, in addition to five known sesquiterpene lactones. The structures were established on the basis of extensive studies of their 1D and 2D (1H-1H COSY, HMQC, HMBC, HOHAHA and NOESY) NMR spectra and FAB mass spectral determinations. The compounds showed good cytotoxic activity when tested using the brine shrimp bioassay.

Phenylphenalenones, metabolites found in Schiekia timida (Haemodoraceae), are a class of specialized metabolites with many biological activities, being phytoalexins in banana plants. In the constant search to solve the problem of glyphosate and to avoid resistance to commercial herbicides, this work aimed to investigate the phytotoxic effect of the methanolic extract of S. timida seeds. The chemical composition of the seed extract was directly investigated by NMR and UPLC-QToF MS and the pre- and post-emergence phytotoxic effect on a eudicotyledonous model (Lactuca sativa) and a monocotyledonous model (Allium cepa) was evaluated through germination and seedling growth tests. Three concentrations of the extract (0.25, 0.50, and 1.00 mg/mL) were prepared, and four replicates for each of them were analyzed. Three major phenylphenalenones were identified by NMR spectroscopy: 4-hydroxy-anigorufone, methoxyanigorufone, and anigorufone, two of those reported for the first time in S. timida. The presence of seven other phenylphenalenones was suggested by the LC-MS analyses. The phenylphenalenone mixture did not affect the germination rate, but impaired radicle and hypocotyl growth on both models. The effect in the monocotyledonous model was statistically similar to glyphosate in the lowest concentration (0.25 mg/mL). Therefore, although more research on this topic is required to probe this first report, this investigation suggests for the first time that phenylphenalenone compounds may be post-emergence herbicides.

Solanum procumbens L. is a medicinal plant belonging to the Solanaceae family. In Vietnam, it is known as "Ca gai leo", and it cultivated in some tropical countries in China, Laos, Cambodia, and Vietnam. From the stem of the ethyl acetate extract of Solanum procumbens, we had isolated one anthraquinone (1), four polyphenols (2-5), and one indole (6). By spectroscopic methods as well as comparing with data in the literature, their chemical structures were elucidated as ziganein (1), benzoic acid (2), salicylic acid (3), 4-hydroxybenzaldehyde (4), vanillic acid (5), and indole-3-carbaldehyde (6). These compounds were isolated for the first time from the genus Solanum.
