OBJECTIVE
Colorectal cancer (CRC) is one of the leading causes of cancer-related death worldwide. Levistolide A (LA), a natural compound isolated from the traditional Chinese herb Ligusticum chuanxiong Hort, is used for treating cancer. In this study, we investigated the anticancer effect of LA in
Five dimeric phthalides were isolated from rhizomes of Ligusticum chuanxiong and their structures deduced based on spectral data. All compounds and their parent extracts were assessed for progesterone-like activity using a progesterone receptor driven reporter-gene bioassay. Among all the compounds,
With the yields of ferulic acid, coniferylferulate, Z-ligustilide, senkyunolide A, butylidenephthalide, butylphthalide, senkyunolide I, senkyunolide H, riligustilide, levistolide A, and total pharmacologically active ingredient as evaluation indexes, the extraction of Ligusticum chuanxiong by
Rhizoma Chuanxiong (Ligusticum chuanxiong HORT.) is a commonly used traditional Chinese medicinal herb for the treatment of cardiovascular disorders. Significant variations of the main components in this herb were observed in commercial samples. The present study investigated effects of post-harvest
Suppression of hepatic stellate cell (HSC) growth and activation, and induction of apoptosis, have been proposed as therapeutic strategies for the treatment and prevention of liver fibrosis. Our previous study showed that the Chinese herb Ligusticum chuanxiong (LC) inhibits platelet-derived growth
High-pressure ultrasound-assisted extraction technology was applied to extract ferulic acid, senkyunolide I, senkyunolide H, senkyunolide A, ligustilide and levistolide A from Ligusticum chuanxiong rhizomes. Seven independent variables, including solvent type, pressure, particle size,
An on-line high performance liquid chromatography (HPLC)-diode array detector (DAD)-mass spectrometry (MS) analytical method has been developed to simultaneously separate and identify seventeen main constituents of Chuanxiong ( Ligusticum chuanxiong Hort.), a traditional Chinese medicinal herb. In
OBJECTIVE
To study the chemical constituents of Ligusticum sinense.
METHODS
The chemical constituents were isolated and purified by column chromatography on silica gel and Sephadex LH-20; Using spectroscopy methods to elucidate their structures.
RESULTS
Nine compounds were isolated and identified as
OBJECTIVE
To study the chemical constituents of the root and rhizoma of Ligusticum jeholense.
METHODS
The constituents were isolated by silica gel column chromatography, Sephadex LH-20 column chromatography and their structures were elucidated through spectral analysis.
RESULTS
Seven compounds were
BACKGROUND
Rhizoma Chuanxiong (RC; Chuanxiong), which is the dried rhizome of Ligusticum chuanxiong (Umbelliferae), is commonly used in Chinese medicine (CM) for improving blood circulation and dispersing blood stasis. RC is usually processed before use in clinical practice to enhance its
A high-performance liquid chromatographic (HPLC) fingerprint of Chinese Angelica (CA) was developed basing on the consistent chromatograms of 40 CA samples (Angelica sinensis (Oliv.) Diels). The unique properties of this HPLC fingerprints were validated by analyzing 13 related herbs including 4
Tyrosine 367 Cysteine-fibroblast growth factor receptor 4 cell membrane chromatography combined with high-performance liquid chromatography and mass spectrometry was developed. Tyrosine 367 Cysteine-HEK293 cells were used as the cell membrane stationary phase. The specificity and reproducibility of
OBJECTIVE
To study the chemical constituents from dry roots of Ligusticum glaucescens Franch.
METHODS
Chromatography and spectrum analysis were employed to isolate and elucidate the chemical constituents in the plant.
RESULTS
4 compounds were isolated and identified as levistolide A (I), ligustilide
The n-hexane extract of Lovage root was found to significantly inhibit the growth of both Mycobacterium smegmatis mc²155 and Mycobacterium bovis BCG, and therefore a bioassay-guided isolation strategy was undertaken. (Z)-Ligustilide, (Z)-3-butylidenephthalide, (E)-3-butylidenephthalide,
OBJECTIVE
To evaluate the chemical changes in Chuanxiong raw material (CX), the rhizome of Ligusticum chuanxiong Hort., during CX storage and further assess its quality variety.
METHODS
Four CX samples were sealed and stored at ambient temperature in room for two years. These samples were quantified
