Cytotoxicity and modes of action of five Cameroonian medicinal plants against multi-factorial drug resistance of tumor cells

2013

Abstract Ethnopharmacological relevance Beilschmiedia acuta Kosterm, Clausena anisata (Willd) Hook, Fagara tessmannii Engl., Newbouldia laevis Seem., and Polyscias fulva (Hiern) Harms. are medicinal plants used in Cameroonian traditional medicine in the treatment of various types of cancers. The present study aims at investigating 11 methanolic extracts from the above Cameroonian medicinal plants on a panel of human cancer cell lines, including various drug-resistant phenotypes. Possible modes of action were analyzed for two extracts from Beilschmiedia acuta and Polyscia fulva and alpha-hederin, the representative constituent of Polyscia fulva. Materials and methods Cytotoxicity was determi…

La pareja Bazo–Estómago y el trayecto de Zuyangming

2015

In this paper, we study the reason why Zuyangming (stomach meridian) travels the body through yin territory in contrast with the other eleven main meridians governed by the quantitative–qualitative yinyang synchronicity of meridians and territories to discover. Zuyangming meets this principle only partially (in face and leg) and that is why we attempt to decipher the reasons for this exception in the thoraco–abdominal trajectory. Ancient traditional medical texts describe the internal and external routes of meridians and the relations between the spleen–stomach pair, which Su Wen 8 transforms into spleenstomach, mentioning the membranous binding (connective tissue today) which unifies both …

¿Por qué moxar Zhi Yin (V 67) puede corregir la malposición fetal?

2015

Many medical works, eastern and western, have described the technique Jiu Fa (moxibustion) of point Zhi Yin (BL 67) (reaching Yin) in order to correct a bad presentation of the fetus and thus facilitate a normal delivery. However, those works do not develop an explanation of the theoretical bases of Chinese medicine that lead to that therapeutic decision, and they do not mention what Nei Jing Su Wen Ling Shu teaches us about which energy path is the one that leads to a correction of the fetal position to allow an eutocic delivery when heat is applied with moxa on the little toe (BL 67). This work, based on classical thinking of Chinese medicine, tries to clarify energy dynamics that explain…

Steroidal glycosides from the Vietnamese cultivar Cordyline fruticosa “Fairchild red”

2021

Abstract A phytochemical study of Cordyline fruticosa “Fairchild red” (Asparagaceae) from Vietnam, led to the isolation of fourteen steroidal glycosides, including twelve previously undescribed along with two known ones. Ten compounds were obtained by successive solid/liquid chromatographic methods from an aqueous-ethanolic extract of the roots, and four from the aerial parts. Their structures were elucidated mainly by spectroscopic analysis 2D NMR and mass spectroscopy (ESI-MS), as spirostanol glycosides, 5α-spirost-25(27)-ene-1β,3β,4α-triol 1-O-β-D-fucopyranoside, 5α-spirost-(25)27-ene-1β,3β,4α-triol 1-O-β-D-xylopyranoside, 5α-spirost-(25)27-ene-1β,3β,4α-triol 1-O-α-L-rhamnopyranosyl-(1 →…

Ethnobotanical research in Cava de' Tirreni area, Southern Italy

2019

Abstract Background To best of our knowledge, this is the first quantitative ethnobotanical study with the aim of documenting the local knowledge and practices of using plants for curing diseases in the Cava de’ Tirreni area, Salerno Province, Campania Region, Italy. The present ethnobotanical field study, carried out during 2016–2017, documents the local uses of 119 plant species for medicinal, food and domestic purposes. Methods Ethnobotanical data were documented from 70 informants: field data were collected and information on the uses of plants was gathered through semi-structured and structured interviews with persons who still retain traditional ethnobotanical knowledge. Documented da…

Medicinal and useful plants in the tradition of Rotonda, Pollino National Park, Southern Italy.

2013

Abstract Background This paper reports an ethnobotanical survey of the traditional uses of medicinal and useful plants in an area of the Pollino National Park, Basilicata, Southern Italy. The study, conducted between 2009 and 2010, gathered information on the medicinal plants traditionally used in the neighbourhood of town of Rotonda, in the Pollino National Park, that appears have very rich and interesting ethnopharmacological traditions. Methods In all, we interviewed 120 key informants, whose age ranged between 50 and 95 years. Results The research resulted to the identification of 78 medicinal plants belonging to 46 families. Among the species reported, 59 are used in human medicine, 18…

Bioactive Constituents of Juniperus turbinata Guss. from La Maddalena Archipelago.

2018

A comprehensive phytochemical study of Juniperus turbinata (Cupressaceae) collected from La Maddalena Archipelago (Sardinia, Italy) is reported. Both the essential oil and the ethanolic extract obtained from the aerial parts were analyzed. The essential oil appears to belong to a new chemotype compared to other Mediterranean juniper accessions, as it was favored by geographic isolation of the isles. It showed a low content of monoterpene hydrocarbons and -terpineol, ent-manoyl oxide, 1,10-di-epi-cubenol as the major constituents. The ethanolic fraction contained mainly diterpenoids. Among these, 15-formyloxyimbricatolic acid (7) is a new natural product since it has hitherto been obtained o…

Phytochemical Analysis and Cytotoxicity Towards Multidrug-Resistant Leukemia Cells of Essential Oils Derived from Lebanese Medicinal Plants

2012

Juniperus excelsa fruit essential oil as well as J. oxycedrus, Cedrus libani, and Pinus pinea wood essential oils have been obtained with yields between 2.2 ± 0.3 % to 3.4 ± 0.5 % and analyzed by gas chromatography. Sesquiterpenes mainly characterized C. libani and J. oxycedrus essential oils, while in P. pinea and J. excelsa, monoterpenes were the most abundant compounds. In J. oxycedrus, cis-calamenene (7.8 %), cuparene (3.8 %), and cis-thujopsenal (2.0 %) have been detected for the first time. The cytotoxic activity of these essential oils against drug-sensitive CCRF-CEM and multidrug-resistant P-glycoprotein-expressing CEM/ADR5000 leukemia cells has been investigated (IC₅₀ values: 29.46…

Phytochemical Constituents, Antioxidant Activity, and Toxicity Assessment of the Aerial Part Extracts from the Infraspecific Taxa of Matthiola frutic…

2021

In a project designed to investigate the specific and infraspecific taxa of Matthiola endemic to Sicily (Italy) as new potential sources of bioactive compounds in this work, the infraspecific taxa of Matthiola fruticulosa were studied, namely, subsp. fruticulosa and subsp. coronopifolia. HPLC–PDA/ESI–MS and SPME–GC/MS analyses of hydroalcoholic extracts obtained from the aerial parts of the two subspecies led to the detection of 51 phenolics and 61 volatile components, highlighting a quite different qualitative–quantitative profile. The antioxidant properties of the extracts were explored through in vitro methods: 1,1-diphenyl-2-picrylhydrazyl (DPPH), reducing power and Fe2+ chelating activ…
