Abstract
Rheumatoid Arthritis (RA) is an autoimmune disorder that generally causes joint synovial inflammation as well as gradual cartilage and degenerative changes, resulting in progressive immobility. Cartilage destruction induces synovial inflammation, including synovial cell hyperplasia, increased synovial fluid, and synovial pane development. This phenomenon causes articular cartilage damage and joint alkalosis. Traditional medicinal system exerts their effect through several cellular mechanisms, including inhibition of inflammatory mediators, oxidative stress suppression, cartilage degradation inhibition, increasing antioxidants and decreasing rheumatic biomarkers. The medicinal plants have yielded a variety of active constituents from various chemical categories, including alkaloids, triterpenoids, steroids, glycosides, volatile oils, flavonoids, lignans, coumarins, terpenes, sesquiterpene lactones, anthocyanins, and anthraquinones. This review sheds light on the utilization of medicinal plants in the treatment of RA. It explains various phytoconstituents present in medicinal plants and their mechanism of action against RA. It also briefs about the uses of polyherbal formulations (PHF), which are currently in the market and the toxicity associated with the use of medicinal plants and PHF, along with the limitations and research gaps in the field of PHF. This review paper is an attempt to understand various mechanistic approaches employed by several medicinal plants, their possible drug delivery systems and synergistic effects for curing RA with minimum side effects.

Abstract
Around 3000 species of Saussurea are known, however Saussurea lappa Clarke
which is perennial herb and has been traditionally used as anticancer, anti-inflammatory,
antiviral, medicine without many adverse effects. Phytochemistry of Saussurea lappa after
thorough literature survey revealed various varied and copious metabolites such as sesquiterpenes,
flavonoids, phytosterols, lignans, terpenes. Many of these compounds have been
found to possess a wide range of biological activity such as anticancer, anti-inflammatory,
anti-hepatotoxic, anti-viral, etc. Among sesquiterpenes particularly Dehydrocostuslactone,
dihydrocostunolide, costunolide Lappadilactone, have been isolated as the main chemical
constituents. This review aims to cover published work from public databases (e.g. PubMed,
Google Scholar, ResearchGate) and Non-English, Ph.D./MS thesis databases (e.g. CKNIChina,
Jairo-Japan, Myto-Malaysia, Shodhganga-India) with a particular focus on

Huang G, Tong Y, He Q, Wang J, Chen Z. Aucklandia lappa DC. extract enhances gefitinib efficacy in gefitinib-resistance secondary epidermal growth factor receptor mutations. JOURNAL OF ETHNOPHARMACOLOGY 2017; 206:353-362. [PMID: 28619365 DOI: 10.1016/j.jep.2017.06.011] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/09/2017] [Revised: 06/06/2017] [Accepted: 06/10/2017] [Indexed: 06/07/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Aucklandia lappa DC. is a widely used medicinal plant in China, India and Pakistan for a long time. Previously, a number of different pharmacological experiments in vitro and in vivo have convincingly demonstrated the abilities of it to exhibit anticancer activities. Reynoutria japonica Houtt. has also been widely used as traditional Chinese medicinal plant. Previous studies have demonstrated that it is bioactive to exhibit anticancer activities. AIM OF THE STUDY This study aims to investigate whether the extracts of Aucklandia lappa DC. and Reynoutria japonica Houtt. are capable of treating drug-resistant non-small cell lung cancer (NSCLC), providing support for novel usage beyond traditional uses. MATERIALS AND METHODS Extracts combined with gefitinib have been tested taking the vulval development of transgenic C. elegans (jgIs25) as an effective and simple in vivo model system, evaluating their efficacy against acquired NSCLC. Synchronous larval 1 (L1) larvae were treated with extracts plus gefitinib and cultured to obtain mainly L4 larvae. The multivulva (Muv) phenotype was recorded at the adult stage. RESULTS Our data showed that Aucklandia lappa DC. extract could significantly enhance the efficacy of gefitinib, suppressing the Muv phenotype of jgIs25. Meanwhile, it could also down-regulate the mRNA and protein expression of EGFR in jgIs25. Collectively, our results verified that the capability of Aucklandia lappa DC. to inhibit Muv phenotype may be based on the EGFR signaling pathway inhibition. CONCLUSION We demonstrated that the co-administration of Aucklandia lappa DC. with gefitinib may provide an effective strategy for the therapy of EGFR inhibitor resistant NSCLCs.

Abstract
There are 300 known Saussurea species. Among them, Saussurea lappa (S. lappa) is a representative perennial herb, globally distributed across Himalaya region. S. lappa has been traditionally used in medicines without obvious adverse effects. Despite significant progress in phytochemical and biological analyses of S. lappa over the past few years, inclusive and critical reviews of this plant are anachronistic or quite limited in scope. The present review aims to summarize up-to-date information on the active constituents, pharmacology, traditional uses, trade and challenges in conservation and sustainable use of S. lappa from the literature. In addition to botanical studies and records of the traditional use of S. lappa in over 43 diseases, scientific studies investigating the latent medicinal uses of this species and its constituent phytochemicals for a range of disorders are presented and discussed. The structure, bioactivity, and likely mechanisms of action of S. lappa and its phytochemicals are highlighted. Although some progress has been made, further scrupulous efforts are required to investigate the individual compounds isolated from S. lappa to validate and understand its traditional uses and develop clinical applications. The present review offers preliminary information and gives direction for further basic and clinical research into this plant.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Radix Aucklandiae (RA), a well known traditional Chinese medicine, is widely used for treating various problems in digestive system. A selective and sensitive high-performance liquid chromatography coupled with mass spectrometry method was first developed and validated for simultaneous quantification of costunolide and dehydrocostuslactone in rat plasma with diazepam as internal standard after oral administration of RA extraction. MATERIALS AND METHODS Plasma samples were extracted via solid-phase extraction and detected by multiple-reaction monitoring mode under positive electrospray. Chromatographic separation was accomplished on an Agilent C18 column (2.1 mm × 150 mm, 5 µm), with 0.1% formic acid and acetonitrile (1:1) as the mobile phase at a flow rate of 0.5 mL/min. RESULTS The quantification was performed using the transitions of m/z 233/187 for costunolide, m/z 231/185 for dehydrocostuslactone and m/z 285/193 for diazepam, respectively. Calibration curves were linear over the concentration range of 0.7-769.7 ng/mL for costunolide and 0.9-956.0 ng/mL for dehydrocostuslactone. The intra-day and inter-day precisions (RSD%) for two compounds was less than 8.76% and 9.70% and the accuracy (RE%) range from 6.14% to 5.35%. The time to reach the maximum plasma concentration (Tmax) was 10.46 h for costunolide, 12.39 h dehydrocostuslactone. The elimination half-time (t1/2) of costunolide and dehydrocostuslactone was 5.54 ± 0.81 and 4.32 ± 0.71 (h). The AUC of costunolide and dehydrocostuslactone was 308.83 and 7884.51 respectively (ngh/mL). CONCLUSIONS It was the first report for the study of pharmacokinetic profile of costunolide and dehydrocostuslactone in rat plasma after oral administration of RA extract. These results provided a meaningful basis for better understanding the absorption of traditional medicine, RA, and provide useful scientific data for clinical application.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Senecio candicans DC (Asteraceae) is used as a remedy for gastric ulcer and stomach pain in the Nilgiris district, Tamil Nadu for which no scientific evidence exists. AIM OF THE STUDY The present study was performed to evaluate the gastroprotective effects and acute oral toxicity of aqueous leaf extract of Senecio candicans (AESC) in experimental models. MATERIALS AND METHODS The antiulcerogenic activity of AESC was performed in two different ulcer models viz., pylorus-ligated model and ethanol-induced model using Wistar albino rats. Acute toxicity study was also performed to get information on the admissible dose for treatment of ulcer. Preliminary phytochemical screening of AESC was performed to find the active principles present, which are thus responsible for the antiulcerogenic activity. DPPH assay was performed to confirm the antioxidant activity of AESC. RESULTS The acute toxicity study did not show any mortality up to 2500mg/kg b.w. of AESC. Both the ulcer models showed gastroprotective effect comparable to that of the standard Omeprazole. The results of antioxidant enzymes, histopathology sections, ATPase and mucus content of gastric secretion showed that several mechanisms are involved in the gastroprotective effect. The preliminary phytochemical screening revealed the presence of alkaloids, flavonoids and steroids in AESC. The DPPH assay confirmed the antioxidant activity of AESC. CONCLUSION The traditional consumption of AESC for the treatment of gastric ulcer is thus true, the antioxidant constituents present in the extract plays a major role in the gastroprotective activity, but since Senecio species are known for the presence of pyrrolizidine alkaloids, a detailed study in future is required to describe the safe dose for a prolonged period.

Abstract
Saussurea costus (Falc.) Lipschitz, syn Saussurea lappa C.B. Clarke is a well known and important medicinal plant widely used in several indigenous systems of medicine for the treatment of various ailments, viz. asthma, inflammatory diseases, ulcer and stomach problems. Sesquiterpene lactones have been reported as the major phytoconstituents of this species. Different pharmacological experiments in a number of in vitro and in vivo models have convincingly demonstrated the ability of Saussurea costus to exhibit anti-inflammatory, anti-ulcer, anticancer and hepatoprotective activities, lending support to the rationale behind several of its traditional uses. Costunolide, dehydrocostus lactone and cynaropicrin, isolated from this plant, have been identified to have potential to be developed as bioactive molecules. Due to the remarkable biological activity of Saussurea costus and its constituents it will be appropriate to develop them as a medicine. The present review is an up-to-date and comprehensive analysis of the botany, chemistry, pharmacology and traditional and folkloric uses of Saussurea costus.

Abstract
Phytogenic agents have traditionally been used by herbalists and indigenous healers for the prevention and treatment of peptic ulcer. This article reviews the anti-acid/anti-peptic, gastro-protective and/or anti-ulcer properties of the most commonly employed herbal medicines and their identified active constituents. Botanical compounds with anti-ulcer activity include flavonoids (i.e. quercetin, naringin, silymarin, anthocyanosides, sophoradin derivatives) saponins (i.e. from Panax japonicus and Kochia scoparia), tannins (i.e. from Linderae umbellatae), gums and mucilages (i.e. gum guar and myrrh). Among herbal drugs, liquorice, aloe gel and capsicum (chilli) have been used extensively and their clinical efficacy documented. Also, ethnomedical systems employ several plant extracts for the treatment of peptic ulcer. Despite progress in conventional chemistry and pharmacology in producing effective drugs, the plant kingdom might provide a useful source of new anti-ulcer compounds for development as pharmaceutical entities or, alternatively, as simple dietary adjuncts to existing therapies.

Abstract
UL-409, a herbal preparation was investigated for its anti-ulcerogenic activity and possible mechanism of action in different experimental models. Oral administration of UL-409 at a dose of 600 mg/kg significantly reduced the volume of gastric secretion, total acidity and free acidity in aspirin + pylorus-ligated rats. The drug appeared to strengthen the gastric mucosal defense mechanism by significantly increasing the total carbohydrate:protein ratio in aspirin + pylorus-ligated rats. The major mechanism involved appears to be due to promotion of mucosal protection by augmenting gastric mucin activity. Pre-treatment with UL-409 showed inhibition of alcohol-induced contraction of isolated rat fundus preparation which was reversed by indomethacin suggesting a possible involvement of the cyclo-oxygenase system.

Abstract
Antiulcer activity of four medicinal plants, Diodia sarmentosa (whole plant), Cassia nigricans (leaves), Ficus exasperata (leaves) and Synclisia scabrida (leaves), which are commonly used by the Nigerian traditional healers for the treatment of peptic ulcer were investigated. Acute toxicity tests were also carried out. The results revealed that the four extracts possess significant anti-ulcerogenic properties in a dose-dependent way. They protected rats from aspirin-induced ulcerogenesis, delayed intestinal transit, increased the pH, and decreased both the volume and acidity of gastric secretion. These results correlate with local use of the plants.
