Abstract
In the present work, a two-dimensional qNMR method for the determination of sennosides was established. Using band-selective HSQC and the cross correlations of the characteristic 10-10' bonds, we quantified the total amount of the value-determining dianthranoids in five minutes, thus, rendering the method not only fast, but also specific and stability indicating. The validation of the method revealed excellent accuracy (recovery rates of 98.5 to 103%), precision (RSD values of 3.1%), and repeatability (2.2%) and demonstrated the potential of 2D qNMR in the quality control of medicinal plants. In a second method, the use of 2D qNMR for the single analysis of sennosides A, B, and A1 was evaluated with acceptable measurement times (31 min), accuracy (93.8%), and repeatability (5.4% and 5.6%) for the two major purgatives sennoside A and B. However, the precision for sennoside B and A1 was not satisfactory, mainly due to the low resolution of the HSQC signals of the two compounds.

Abstract
Many biologically-active plant-derived compounds have therapeutic or chemopreventive effects. The use of plant in vitro cultures in conjunction with modern genetic engineering techniques allows greater amounts of valuable secondary metabolites to be obtained without interfering with the natural environment. This work presents the first findings concerning the acquisition of transgenic hairy roots of Senna obtusifolia overexpressing the gene encoding squalene synthase 1 from Panax ginseng (PgSS1) (SOPSS hairy loot lines) involved in terpenoid biosynthesis. Our results confirm that one of PgSS1-overexpressing hairy root line extracts (SOPSS2) possess a high cytotoxic effect against a human acute lymphoblastic leukemia (NALM6) cell line. Further analysis of the cell cycle, the expression of apoptosis-related genes (TP53, PUMA, NOXA, BAX) and the observed decrease in mitochondrial membrane potential also confirmed that the SOPSS2 hairy root extract displays the highest effects; similar results were also obtained for this extract combined with doxorubicin. The high cytotoxic activity, observed both alone or in combination with doxorubicin, may be due to the higher content of betulinic acid as determined by HPLC analysis. Our results suggest synergistic effects of tested extract (betulinic acid in greater amount) with doxorubicin which may be used in the future to develop new effective strategies of cancer chemosensitization.

Abstract
BACKGROUND Cassiae semen has been used as the tea or medicine component to treat hyperlipidemia or for hepatoprotection. However, Cassiae semen was reported to be a potentially hepatotoxic herb, and the underlying hepatotoxicity mechanisms or specific hepatotoxic components of Cassiae semen are unknown. PURPOSE In this study, we aimed to explore the potential hepatotoxicity mechanisms and the hepatotoxic components of Cassiae semen. METHODS Both young adult male and female SD rats were orally administrated with the aqueous extract of the seeds of Senna obtusifolia (L.) H.S.Irwin & Barneby at doses of 4.73, 15.75, 47.30 g/kg for 28 days, and the body weight, liver coefficient, bile acids, histopathology, serum levels of TC, TG, LDL, HDL, ALP, ALT, AST, and LDH were examined. Lipidomic analysis of rat serum was performed by LC-MS to investigate the specifically changed lipids caused by the aqueous extract treatment. The components absorbed in plasma were detected by UHPLC-Q-Exactive-MS. MTT assay was used to evaluate the cytotoxicity of these components absorbed in plasma. RESULTS The serum levels of ALP, AST, ALT, LDH were increased on day 7 with some of which gradually dropped to normal level on day 28. In high dose of the aqueous extract treated group, the histopathological changes were observed based on the cytoplasmic vacuolation in the liver and the increase of bile acids, indicating the hepatotoxicity of the aqueous extract. The changes of TC, TG, LDL, HDL indicated the disorder of lipid metabolism. By comparing the difference in lipids between high dose group and control group, the results showed that the alterations were primarily focused on glycerophospholipid metabolism in both male and female rats. In addition, the glycerolipid metabolism in female rats also changed. Further analyses found that PC (18:2/20:4) and LysoPC 18:0 were significantly increased. Among these phytochemicals detected in plasma, nine components in the aqueous extract were considered to have the highest concentrations, particularly some types of anthraquinones (AQs) existing in Cassiae semen (AQs-in-CS), such as obtusifolin, aurantio-obtusin, and obtusin. The MTT assay showed that emodin, obtusifolin, rhein, aurantio-obtusin, and obtusin inhibited cell viability. Considering plasma concentrations and cytotoxicity of these components, our study indicates that the AQs-in-CS (obtusifolin, aurantio-obtusin and obtusin), emodin and rhein are the potential hepatotoxic phytochemicals in the aqueous extract.

Abstract
Senna species and anthraquinone derivatives generated by these organisms, rhein and aloe-emodin, exert anti-inflammatory effects. These species present a similar morphology but produce different ingredients when they are used as medicinal products. In this study, a DNA barcoding- (Bar-) high-resolution melting (HRM) technique was developed using internal transcribed sequence 2 (ITS2) to differentiate between Senna alata and Senna tora as a result of significant differences in their melting profiles. We used this approach for confirmation of S. alata and S. tora raw materials, and we examined the chondroprotective properties of the ethanolic extracts of S. alata and S. tora using a porcine model of cartilage degradation induced by a combination of interleukin-17A (IL-17A) and IL-1β. We found that both Senna ethanolic extracts, at a concentration of 25 μg/mL, effectively prevented cartilage degradation. Rhein and aloe-emodin were present in the extract of S. alata but not in that of S. tora. We observed a reduction in the release of sulfated glycosaminoglycans (S-GAGs) and hyaluronic acid (HA) into media in both treatments of Senna extracts, which indicated proteoglycan preservation in explant tissues. These results suggest that neither rhein nor aloe-emodin are the main factors responsible for cartilage-protecting properties. Taken together, results show that both S. alata and S. tora are promising for further development as anti-osteoarthritic agents and that Bar-HRM using ITS2 could be applied for species confirmation with Senna products.

Abstract
Senna (Cassia angustifolia Vahl.) is a world's natural laxative medicinal plant. Laxative properties are due to sennosides (anthraquinone glycosides) natural products. However, little genetic information is available for this species, especially concerning the biosynthetic pathways of sennosides. We present here the transcriptome sequencing of young and mature leaf tissue of Cassia angustifolia using Illumina MiSeq platform that resulted in a total of 6.34 Gb of raw nucleotide sequence. The sequence assembly resulted in 42230 and 37174 transcripts with an average length of 1119 bp and 1467 bp for young and mature leaf, respectively. The transcripts were annotated using NCBI BLAST with 'green plant database (txid 33090)', Swiss Prot, Kyoto Encylcopedia of Genes & Genomes (KEGG), Cluster of Orthologous Gene (COG) and Gene Ontology (GO). Out of the total transcripts, 40138 (95.0%) and 36349 (97.7%) from young and mature leaf, respectively, were annotated by BLASTX against green plant database of NCBI. We used InterProscan to see protein similarity at domain level, a total of 34031 (young leaf) and 32077 (mature leaf) transcripts were annotated against the Pfam domains. All transcripts from young and mature leaf were assigned to 191 KEGG pathways. There were 166 and 159 CDS, respectively, from young and mature leaf involved in metabolism of terpenoids and polyketides. Many CDS encoding enzymes leading to biosynthesis of sennosides were identified. A total of 10,763 CDS differentially expressing in both young and mature leaf libraries of which 2,343 (21.7%) CDS were up-regulated in young compared to mature leaf. Several differentially expressed genes found functionally associated with sennoside biosynthesis. CDS encoding for many CYPs and TF families were identified having probable roles in metabolism of primary as well as secondary metabolites. We developed SSR markers for molecular breeding of senna. We have identified a set of putative genes involved in various secondary metabolite pathways, especially those related to the synthesis of sennosides which will serve as an important platform for public information about gene expression, genomics, and functional genomics in senna.

Abstract
Herbal medicine is widely used worldwide and is associated with side-effects such as skin eruptions. Herbal drugs are often produced by combining multiple crude drugs, mostly of plant origin. Determining which medi-cinal plants are associated with the herbal drugs that induce skin eruptions can therefore be difficult. This study investigated mRNA expression of several cytokines in peripheral mononuclear cells (PBMCs) from two patients with herbal drug-induced skin eruptions; one reacted to keishi-bukuryo-gan (KBG), composed of 5 medicinal plants, and the other patient reacted to senna. PBMCs (1×106) from the 2 patients were cultured for 24 h with the supernatant from the medicinal plants from KBG or senna in various concentrations, and a reverse transcription-polymerase chain reaction (RT-PCR) analysis was performed. A high mRNA level of interleukin (IL)-4 and IL-5 was detected in PBMCs stimulated by KBG and two of its components. Senna stimulated a high level of IL-4 and IL-5 mRNA levels in PBMCs from patient with senna-induced drug reaction.

Abstract
Senna alata is locally used in South Eastern Nigeria in the treatment of several infections which include ringworm and other parasitic skin diseases.The larvicidal activities of aqueous and ethanolic leaf and stem extracts of S. alata were evaluated in static bioassays, on fourth instar larvae of Anopheles gambiae, Culex quinquefasciatus and Aedes aegypti, at extract concentrations of 0.15, 0.30, 0.45, 0.60 and 0.75% w/v, for 72 hours. Mortality of larvae exposed to the different extracts increased with increase in extract concentration and time of exposure. This study revealed a differential potency of the extracts used and a difference in susceptibility of larvae to the extracts as evident by the 72hLC₅₀ values obtained. The leaf extract proved to be more lethal to the larvae than the stem extract as judged by the 72hLC₅₀ values obtained both for the aqueous as well as the ethanolic extracts assayed. Phytochemical screening of the plant parts investigated revealed the presence of some plant metabolites, which have been reported in separate studies to be lethal to mosquito larvae. Results obtained from this study suggest that the leaf and stem extracts of S. alata possess a promising larvicidal potential which can be exploited in mosquito vector control.

Abstract
As a contribution to the on-going search for alternative, available and affordable treatment of common infections in Sub-saharan Africa, the efficacy of local herbs, Senna alata(Linn) and Borreria ocymoides (Burm), in comparison with conventional drugs, griseofulvin and clotrimazole in the treatment of dermatophytosis among primary school children, was examined in the three districts of Cross River State, South-South Nigeria. Out of 840 pupils screened, 68 (8.1%) were infected, with incidence ranging from 11 (1.3%) in the southern to 33 (3.9%) in the northern districts, indicating a widespread of the infection. Specimens taken from the infected pupils and analyzed for the causative agents, showed that Trichophyton tonsurans 29 (20.4%) followed by Microsporum soudanense 24 (16.9%) was most frequent. The greater sensitivity of the isolated dermatophytes to the local plants than the chemotherapeutic drugs (control) offers some hope of treatment and control. The antifungal activity of the plants was associated with their very high levels of chemical components, saponins, anthraquinones and flavonoids. We recommend further studies on the chemical properties and safety of the plants before total dependence on them for treatment.

Abstract
Interactions between widely used anthranoid laxatives and other simultaneously administered drugs are not known. In this paper, the influence of rhein, danthron, sennidins A/B, sennosides A/B, and senna leaf infusion was investigated on the permeability of furosemide, ketoprofen, paracetamol, propranolol, verapamil, digoxin, and Rhodamine 123 across Caco-2 monolayers. The effects on monolayer integrity ([(14)C]mannitol permeability, TEER) were also determined. The in vitro absorption of highly permeable drugs was not strongly affected during co-administration of the laxatives. Furosemide permeability was enhanced by rhein and danthron (3.6 and 3.0-fold), which may partly be due to opening of the paracellular spaces and/or effects on active efflux. However, the secretory permeability of digoxin and Rho 123 was not strongly affected by rhein and danthron, suggesting that inhibition of MDR1 was not responsible for the increased permeation of furosemide. The absorptive permeability of digoxin was decreased by rhein and danthron, offering evidence for effects on apical membranes. The effects on monolayer integrity were detectable, but reversible. According to presented experiments, daily use of laxatives with well-absorbing drugs would seem unlikely to affect drug permeability, but the effects on the absorption of poorly permeable drugs cannot be excluded.

Abstract
Powdered senna leaves and a commercial methanolic senna leaf extract were investigated for apparent degradation pathways of known constituents. Different defined storage conditions were chosen according to the guidelines of the international conference on harmonization. Analytical fingerprinting was carried out by HPLC with photodiode array detection. Differences in degradation pathways were observed between the powdered herbal drug material and the extract, depending on storage conditions and packaging materials. Within the crude plant material sennosides were shown to be degraded to sennidine monoglycosides, while rhein 8-O-glucoside was hydrolysed to rhein by enzymatic processes. Degradation of the anthranoid compounds was not due to the same pathways in the investigated commercial extracts. Only unspecific alterations of all compounds were observed. Forced decomposition of this herbal drug preparation under high temperature caused oxidative decomposition of the sennosides to rhein 8-O-glucoside. Furthermore flavonoid glycosides decomposition were observed with an apparent increase in the content of flavone aglyca.

Abstract
A method for the separation and determination of sennosides A and B and the main composition (sennidins A and B) in degraded products of sennosides by linear gradient high performance liquid chromatography has been developed. Separation conditions were as follows: column, a Spherisorb C18 column (250 mm x 4.6 mm i.d., 10 microm); column temperature, 40 degrees C; detection wavelength, 360 nm; mobile phase A, 1.25% acetic acid aqueous solution; mobile phase B, methanol; linear gradient, 100% A --> (20 min) 100% B. The method is effective, quick, accurate and reproducible. The satisfactory results show that this new method has certain practical values as an approach of real-time analysis in the process of sennoside metabolism.

Abstract
From the hexane extract of the bark of the stems of Senna racemosa (syn. Cassia racemosa) a new dihydroanthracenone derivative, named racemochrysone, was isolated. Its structure was established as 8,9-dihydroxy-3-methoxy-2,2,6-trimethyl-(2H)-anthracen-1-one based on spectroscopical data, mainly 1D and 2D NMR experiments. In addition beta-sitosterol, stigmasterol, chrysophanol and physcion were obtained. From the leaves extracts the piperidine alkaloid cassine and the hexitol pinitol were obtained.

Abstract
BACKGROUND Senna laxatives are used worldwide. However, their misuse can lead to chronic mucosal inflammation with the accumulation of pigment-laden leukocytes and may cause colon cells to undergo apoptosis. This study explores the mechanisms by which rhein, an active component of senna, acts on a human intestinal cell line to induce ion secretion, apoptosis, and indirect chemotaxis of polymorphonuclear leukocytes. METHODS Human colonic adenocarcinoma (CaCo-2) monolayer cells, in the presence or in the absence of rhein, were used to monitor the production of reactive nitrogen species using the Griess reaction. Modified Ussing chambers were used to study electrolyte secretion. The capacity to recruit human polymorphonuclear leukocytes was evaluated using masked well chemotaxis chambers. Rhein-induced apoptosis was investigated by counting apoptotic nuclei stained with Hoechst 33258 dye. RESULTS Rhein caused a dose-dependent increase in short-circuit current that was abolished in chloride-free bathing buffer or by preincubating with 100 micromol/L NG-nitro-L-arginine (L-NAME) methyl ester. The concentration that maximally stimulated intestinal secretion, 50 micromol/L rhein, induced nitrate production. Supernatants obtained from CaCo-2 cultures after incubation with 50 micromol/L rhein stimulated a time-dependent polymorphonuclear leukocytes chemotaxis that was significantly decreased with 100 micromol/L L-NAME, whereas rhein per se was not active. Neutralizing antibodies anti-interleukin-8 (IL-8) and anti-ENA78 also inhibited chemotaxis. Overnight rhein incubation produced an increased number of apoptotic cells in the culture supernatant that was significantly decreased by preincubation with 100 micromol/L L-NAME. Light-degraded rhein had no effects on CaCo-2 monolayers. CONCLUSIONS The integrity of rhein is crucial to generating nitric oxide, which mediates, with different time courses, ion secretion, chemotaxis, and apoptosis of human-derived cells.

Abstract
The hydroalcoholic extract of Tinnevelli senna is widely used as a laxative phytomedicine. In order to improve the knowledge of the chemical composition of this extract, LC/MS and LC/MS(n) studies were performed, allowing the on-line identification of most of the known constituents, i. e., flavonoids, anthraquinones and the typical dianthronic sennosides. However, the identity of four compounds could not be ascertained on-line under the given LC/MS conditions. These substances were isolated and their structures elucidated as kaempferol, the naphthalene derivative tinnevellin 8-glucoside and two new carboxylated benzophenone glucosides.

Abstract
OBJECTIVE Compare effectiveness of antegrade bowel preparation by liquid diet, polyethylenglycol (PEG) and electrolytes solution plus sennosides A and B, vs. liquid diet plus sennosides A and B only. BACKGROUND DATA Preparation for colonoscopy with a balanced solution (PEG and electrolytes) has some physiological advantages. Nonetheless, drawbacks of such preparation include nasty flavor, large volumes and low availability in our country. METHOD A randomized, comparative, prospective, transversal and blind trial that included 200 patients scheduled for colonoscopy were randomly assigned (one hundred each group) to receive: group 1: liquid diet, sennosides A and B and a two litter of solution with PEG and electrolytes; and group 2: liquid diet plus sennosides A and B. Compliance, tolerance and effectiveness of both preparations were evaluated blindly. The results were assessed by Student's T test. RESULTS The effectiveness of group 2 preparation proved superior (p < 0.05) to group 1. Tolerance and side effects were similar for both groups with no related complications.

Abstract
Laxative senna products and several of their specific components have been submitted to a large number of genetic tests. While most studies gave negative responses, results from some of the studies suggest that components of senna products, particularly emodin and aloe-emodin, have genotoxic activity. Assessment of the genotoxicity profile of these substances, in light of other data from animal and human metabolism or kinetic studies, human clinical trials and rodent carcinogenicity studies do not support concerns that senna laxatives pose a genotoxic risk to humans when consumed under prescribed use conditions.

Abstract
The seeds of Senna multijuga were extracted with water or 1% acetic acid and treated with ethanol, resulting in two insoluble fractions. After purification, the major one (FIA, 23%) was shown to be a galactomannan (Man:Gal 2.3:1; [alpha] = +54.6; [eta] = 1340 ml g-1). It consists of a main chain of (1-->4)-linked beta-D-mannopyranosyl residues substituted at O6 by single-unit alpha-D-galactopyranosyl side chains. The second fraction (FIB, 2.5%) was an O-acetyl-glucuronoarabinoxylan from the seed coats (O-acetyl 8.3 mol%; glucuronic acid 11.7%, Xyl:Ara ratio 20:1), which showed a predominance of 4-O-substituted Xylp units (84.4%), branched at O3 with non-reducing end units of Xylp, Araf and glucuronic acid. The O-acetyl positions in D-xylosyl units are at O2 (4.8%), O3 (4.4%) and O2,3 (0.9%). The ratio between O3 and O2 determined by 13C-nuclear magnetic resonance spectroscopy is 1.5:1.

Abstract
Senna consists of the dried leaflets or fruits of Cassia senna (C. acutifolia) known in commerce as Alexandrian senna and of Cassia angustifolia commonly known as Tinnevelly senna. The senna plants are small shrubs of Leguminosae cultivated either in Somalia, the Arabian peninsula and near the Nile river. Tinnevelly senna is obtained from cultivated plants mainly in South India and Pakistan. Owing to the careful way in which the plant is harvested, the leaflets of the drug are usually little broken. Damaged leaves and lower quality products are often used for making galenicals. The senna pods (fruits) are collected during the same period as the leaves, then dried and separated into various qualities. The active principle of Senna was first isolated and characterized by Stoll in 1941. The first two glycosides were identified and attributed to the anthraquinone family. These were found to be dimeric products of aloe emodin and/or rhein which were named sennoside A and sennoside B. They both hydrolyze to give the aglycones sennidin A and B and two molecules of glucose. Later work confirmed these findings and further demonstrated the presence of sennosides C and D. Small quantities of monomeric glycosides and free anthraquinones seem to be present as well. The active constituents of the pods are similar to those of the leaves but present in larger quantities. Two naphthalene glycosides isolated from senna leaves and pods are 6-hydroxymusicin glucoside and tinnevellin glucoside. Both compounds can be utilized to distinguish between the Alexandrian senna and the India senna, since tinnevellin glucoside is only found in the latter and the first only in the C. senna.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Toxicological studies indicate that two hydroxyanthraquinones (HAs), aloe-emodin and emodin, present as minor components in senna, might represent a genotoxic or cancerogenetic risk for man. Since aloe-emodin and emodin occur in senna in the free form as well as their glucosides and dianthrone glucosides, a HPLC method was established to allow the quantification of all free and glycosidic 1,8-dihydroxy anthranoids. The sum of the free HAs and their calculated content in each of their prodrug forms is defined as the potential HA content. For the comparison of different senna drugs in respect to the genotoxic risk arising from their potential aloe-emodin or emodin contents, a risk index has been established.
