Planta Medica Issue 9 2013 now available
 |
Dear Colleague, Welcome to the 9th issue of the Planta Medica Newsletter 2013! In this Planta Medica issue I have selected a review, a pharmacological and an analytical study to be highlighted. Harlev et al. have reviewed natural products originating from plants of the Cactaceae family with cancer preventive or curative properties, a still largely unexploited area of research. Hot flushes are the most common and distressing symptom accompanying the menopausal transition in women; finding an alternative treatment is of importance as increasing numbers of women become reluctant to rely on classical hormone replacement therapy. Rahte et al. have investigated the mechanism of action and the active principles of Salvia officinalis against hot flushes. It is suggested that common and ubiquitous estrogenic flavonoids are involved in its anti-hot flush effect. |
  |
Finally, Zeng et
al. have developed and validated a quantitative liquid
chromatography–electrospray ionization–mass spectrometric method for the
simultaneous determination of 18 bioactive constituents in Tripterygium wilfordii,
which is widely distributed in southern China. The stem and root of T. wilfordii, known as
"Leigongteng" (in Chinese "thunder god vine"), are used
in traditional Chinese medicine, and play a significant role in the clinical
treatment of rheumatoid arthritis in China.
It is my pleasure to offer you free access to these publications! |
Sincerely,  Luc Pieters Planta Medica, Editor-in-Chief |

Cancer Preventive and
Curative Attributes of Plants of the Cactaceae Family: A
Review
(FREE ACCESS) Eli Harlev, Eviatar Nevo, Elaine Solowey, Anupam Bishayee |
 |
The
ever-increasing occurrence of cancer and the severe side effects and limited
efficacy of current cancer chemotherapy based on chemical drugs shift the
attention toward drugs of plant origin.
The Cactaceae family comprises more than 1500 species, but until recently only a few of them have been tested for their chemopreventive and anticancer attributes, leaving a wide unexplored area still waiting for researchers to be investigated. |
Considering
this fact, and also the promising results obtained with the relatively few
plants of this family already tested, it should justly be expected that some
plants of the Cactaceae
family yet unexplored might possess outstanding anticancer attributes,
exceeding those displayed by the plants already tested.
This review presents in vitro and in vivo experimental evidence on cancer chemopreventive and therapeutic potential of bioactive phytoconstituents and extracts derived from cactus plants. It also examines the underlying biochemical and molecular mechanisms involved in the antineoplastic effects of plants of the Cactaceae family. Current limitation and future directions of research towards effective use of cacti to develop efficient and side effect-free future cancer-preventive and anticancer drugs are also discussed.

Salvia officinalis for Hot Flushes: Towards Determination of Mechanism of
Activity and Active Principles (FREE ACCESS)

Herbal
medicinal products are commonly used in alternative treatment of menopausal
hot flushes. In a recent clinical study, Salvia
officinalis tincture was found to reduce hot flush frequency and
intensity.
The aim of the current study was the investigation of the mechanism(s) responsible for the anti-hot flush activity of S. officinalis and determination of its active principle(s). The 66% ethanolic tincture, as well as the n-hexane, CHCl3, and aqueous ethanolic subextracts obtained from the |
tincture
were studied in vitro
for two of the most relevant activities, estrogenicity and selective
serotonin reuptake inhibition. Because of an increased risk of menopausal
women to suffer from Alzheimer's disease, an in vitro acetylcholinesterase inhibition
assay was also employed. No activity was observed in the selective serotonin
reuptake inhibition or the acetylcholinesterase inhibition assays at the
highest test concentrations. The tincture showed no estrogenic effects whereas
the aqueous ethanolic subextract exhibited estrogenicity in the ERLUX assay
with an EC50 value of 64 µg/mL. Estrogenic activity-guided
fractionation of the aqueous ethanolic subextract by a combination of
reverse-phase vacuum liquid chromatography and gel chromatography identified
luteolin-7-O-glucuronide (EC50 129 µg/mL) as the active component
of the vacuum liquid chromatography fraction 4 (EC50 69 µg/mL).
Luteolin-7-O-glucoside was identified as the putative estrogenic principle of
the most potent minor fraction (EC50 0.7 µg/mL) obtained from the
initial vacuum liquid chromatography fraction 7 (EC50 3 µg/mL).
This study suggests the involvement of common and ubiquitous estrogenic
flavonoids in the anti-hot flush effect of Salvia
officinalis, a safe and commonly used herbal medicinal product
during the menopause. Read more

Simultaneous Quantification
of 18 Bioactive Constituents in Tripterygium wilfordii Using Liquid Chromatography-Electrospray Ionization-Mass
Spectrometry (FREE ACCESS)
Feng Zeng, Wei Wang, Shuhong Guan, Chunru Cheng, Min Yang, Bharathi Avula, Ikhlas A. Khan, De-an Guo |
 |
A
liquid chromatography – electrospray ionization – mass spectrometry method
with multiple reaction monitoring was established for simultaneous
quantification of 18 bioactive constituents from the stem and root of Tripterygium wilfordii
Hook. f. collected from different places in China and various commercial
preparations.
|
The
chromatographic separations were achieved on an Agilent Poroshell SB–C18
column (150 × 4.6 mm, 3.5 µm) with gradient elution using acetonitrile and 0.03%
formic acid aqueous solution in 45 min. Detection was performed in the
positive ionization mode by monitoring the precursor–product combination. The
validation of the method included tests of linearity, sensitivity, precision,
repeatability, stability, and accuracy. All calibration curves showed good
linearity (r > 0.9990) within the test range. The established method
showed good precision and accuracy with intraday and interday variations of
2–5% and 1–4%, respectively, and recoveries of 95.5–104.5%. Read more
