Aucklandia costus (Syn. Saussurea costus): Ethnopharmacology of an endangered medicinal plant of the himalayan region.
Aucklandia costus Falc. a medicinal plant is native to the Himalayan region and synonymous with Saussurea costus, Saussurea lappa, and Aucklandia lappa. It has an ancient background of being used ethnopharmacologically for various body ailments. According to Ayurveda, Unani, Siddha, and Traditional Chinese Medicine, Costus roots are recommended for leukoderma, liver, kidney, blood disorders, Qi stagnation, and tridosha. Root and powder are used orally with warm water to cure gastric problems, and the paste is applied to the inflamed area to relieve pain. Root paste is applied on the skin to cure boils, blisters, and leprosy.
The aim of the present review is to establish a correlation among the ethnopharmacological uses and scientific studies conducted on A. costus with chemical constituents, safety & toxicity data including future directions for its conservation with higher yield and effect.
The study was conducted by studying books, research papers, and literature in history, agroforestry, phytopharmacology of Himalayan plants using international databases, publication, Red data book, and reports. The search engines: Pubmed, Scopus, Wiley Inter-science, Indian Materia Medica, Science Direct, and referred journals are referenced.
The literature collected from databases, journals, websites, and books mentioned the use of costus roots in local and traditional practices. CITES included A. costus in a critically endangered category due to lack of cultural practices and overexploitation from wild. A. costus roots are known since 13th century for use in ancient Ayurvedic products but the scientific evaluation is of future research interest. A correlation of traditional uses with scientific studies has been explored to assess the effect of root powder, extract, oil and isolated constituents: Costunolids, Saussureamine B and Dehydrocostus lactone etc. in gastric ulceration and lesions; inhibition of antigen-induced degranulation, mucin production, number of immune cells, eosinophils, and expression and secretion of Th2 cytokines (IL-4 and IL-13) in asthma. The inhibition of pro-inflammatory mediators is also reported by Cynaropicrin, Alantolactone, Caryophyllene, Costic acid. Also, the sesquiterpene lactones has profound effect in inhibition of inflammatory stages and induced apoptotic cascades in cancer. Very few data on the safety and toxicity of plant parts have been noted which needs to be evaluated scientifically.
A. costus have been noted to have remarkable effect for gastric, hepatic, inflammatory, respiratory, cancer, skin problems but there were several errors in selection of plant material, authentification, selection of dose, assessment, selection of standard and control have been identified. Therefore, a schematic drug development and research strategy exploiting the potential of plant extract, fraction, products and probable constituents, costunolide, dehydrocostus lactone, cynaropicrin, saussureamine assuring dose-response relationship and safety may be determined under pre-clinical which may be extrapolated to clinical level. An evaluation of phytochemicals in A. costus collected from different geographical location in Himalayas may be drawn to identify and conserve the higher yielding plant.

UPLC/MS/MS method for quantification and cytotoxic activity of sesquiterpene lactones isolated from Saussurea lappa.
Saussurea lappa (Asteraceae) roots have been reputed for the usage in traditional medicinal systems of India, China and Japan for the treatment of various kinds of disorders such as anti-ulcer, anti-convulsant, anti-cancer, hepatoprotective, anti-arthritic and anti-viral activities.
Compounds were isolated using a column chromatographic technique. The root extract, fractions and isolated compounds were tested for cytotoxicity against A549 (human lung carcinoma) and C-6 (rat glioma) cells using the Sulphorhodamine B assay. Chromatographic separations of active sesquiterpene lactones were accomplished on BEH-HSS-T3 column at 25°C.
Phytochemical investigation of Saussurea lappa root extract resulted in the isolation of isoalantolactone (1), β-cyclocostunolide (2) α-cyclocostunolide (3), 4-hydroxy-3,5-dimethoxycinnamyl-9-O-β-D-glucopyranoside (4), sucrose (5), and alantolactone (6). Their structures were determined by spectroscopic means. Ethanolic extract, chloroform fraction, compounds 1, 2, 3 and 6 possessed significant activity against both tested cells. The quantification was performed using the transitions of m/z 233/105 for isoalantolactone and m/z 233/105 for alantolactone respectively. Costunolide and dehydrocostus lactone were also characterised by comparison of MS/MS fragmentation pattern.
This is the first study on simultaneous quantification of isoalantolactone and alantolactone by the UPLC/MS/MS method in Saussurea lappa. Our study against A549 and C-6 cells showed higher cytotoxicity. It is suggested that roots of Saussurea lappa might be a potential source of anticancer compounds.

Antitrypanosomal sesquiterpene lactones from Saussurea costus.
In the course of a larger screen of 1800 plant and fungal extracts, the ethyl acetate extract of Saussurea costus roots potently inhibited the growth of Trypanosoma brucei rhodesiense. Subsequent HPLC based activity profiling led to the identification of the sesquiterpene lactones arbusculin B (1), α-cyclocostunolide (2), costunolide (3), and dehydrocostuslactone (4). They were tested for in vitro antitrypanosomal activities and cytotoxicity alongside the structurally related sesquiterpene lactones parthenolide (5), zaluzanin D (6), and eupatoriopicrin (7), and had IC(50)s between 0.8 and 22 μM. Cytotoxic IC(50)s were from 1.6 to 19 μM, and selectivity indices from 0.5 to 6.5.
