impatiens niamniamensis/抗癌药

We have previously shown that ethanol or chloroform extracts of the leaves of Impatiens balsamina (LIB) have anti-tumor activity against the human hepatocellular carcinoma cell line HepG2. The ethanol extracts were separated into five fractions according to polarity. An MTT assay indicated that two

OBJECTIVE To study the chemical constituents of seeds of Impatiens balsamina. METHODS The chemical constituents of the plant were isolated and purified by column chromatography and their structures were elucidated on the basis of physicochemical properties and spectral date. RESULTS A new

Impatiens balsamina is both an ornamental and pharmacologically important plant widely distributed in many Asian countries. The leaf of the plant contains many secondary metabolites possessing anti-microbial, anti-tumour and anti-cancer properties. Though there are many phytochemical studies

OBJECTIVE In the present study, we investigated the efficacy of a methanol extract from Impatiens balsamina L. (MEIB) against HSC-2 human oral cancer cells. METHODS The anti-cancer efficacies of MEIB were performed by methanethiosulfonate assay, phospho-kinase array, Western blot,

Impatiens balsamina L. is a tropical ornamental and traditional medicinal herb rich in natural compounds, especially 2-methoxy-1,4-naphthoquinone (MNQ) which is a bioactive compound with tested anticancer activities. Characterization of key genes involved in the shikimate and

Impatiens glandulifera has been imported from Himalaya in Europe and is considered as an invasive alien plant whose spreading arouses increasing interest among scientific literature. Via anti-cancer bioguiding, two new glucosylated steroids, named glanduliferins A and B, were isolated from the dried

A new lanostane-type triterpene glycoside, impatienside A (1), was isolated from the sea cucumber Holothuria impatiens, together with a structurally related, known compound, bivittoside D (2). Their structures were elucidated by in-depth spectroscopic and mass-spectrometric methods, including (1)H-,
