“…It is well established that biosynthesis of active principles in medicinal plants is largely depends on the environmental conditions [21,22]. Variations found in the contents of curcuminoids in two samples may be due to their two different habitats -Sample A growing in plains, whereas Sample B growing in Western Ghats region.…”

Objective: To estimate the contents of curcuminoids in two samples of Curcuma karnatakensis collected from different localities.Methods: Quantification of curcuminoids was estimated by ultra-high performance liquid chromatography-mass spectrometry/selected reaction monitoring (UHPLC-MS/SRM) method in two samples of C. karnatakensis for the first time. Fine powder of rhizomatous rootstocks of two plant samples collected from different habitats were served as Samples A and B. The MS used for the metabolite analysis is a Vantage TSQ triple stage quadrupole MS equipped with heated electrospray ionization. The MS is coupled with an Agilent 1290 infinity UHPLC system. A stock solution of curcuminoid standard was prepared by dissolving 5 mg of standard in 1 mL of methanol. Seven different concentrations of standard (0.15-10 ng on column) were injected for the UHPLC-MS/SRM analysis. Separations were performed using a C-18 column with a flow rate of 0.2 mL/minute. Results:Contents of curcumin, demethoxycurcumin, and bisdemethoxycurcumin were found to be varied in two samples and lowest than any other species of Curcuma studied. Variation in the contents may be due to their different habitats in which they are growing. Conclusion:The present attempt of analyzing the contents of curcuminoids in this endemic taxon for the first time will provide the basis for further pharmacological analysis to authenticate the efficacy of these active principles as the curcuminoids are known for varied pharmacological activities.

Higher plants are the major source of crude drugs used in herbal therapy. Adulteration in crudedrug material has necessitated scientific characterization of plant drugs, which is based primarily on morphological, anatomical and physico-chemical characters studied through microscopy and some analytical techniques. These criteria are helpful in isolating the adulterants from the actual drug, but fail to deliver when the very botanical identity of a plant drug is controversial, and several different plant species are used under a single drug name. This article suggests how to face this situation and overcome the problems likely to occur. Quantification of active ingredients in plant tissues is the only dependable way to identify the actual drug out of the different species in use. However, the amount of active ingredients in plants, responsible for the therapeutic efficacy of those plants, may vary with plant genotype and the habitat ecology, regulated largely by soil c h a r a c t e r s a n d a g r o -c l i m a t i c conditions. Even within the individual plant, concentration of active ingredients often varies with plant p a r t s / o r g a n s , s t a g e o f p l a n t development and status of plant nutrition. Besides, degradation of environment may not only affect the quantity, but even the composition of the secondary metabolites produced. This situation may alter the chemical properties, and hence the degree of therapeutic effectiveness of these bioactive compounds. Thus, a careful estimation of active ingredients, taking all the above-said situations into account, may decide which species should be regarded as the actual drug, which as an alternative drug and which as the non-drug (if the amount of the ingredient in question is just negligible). It may also indicate which plant organ should preferably be used and what should be the proper stage for harvesting. Further, environmental degradation may have a far-reaching influence on the therapeutic potential of medicinal plants and may also necessitate a re-fixing of drug doses, keeping in view the overall impact of environmental degradation on the active ingredients of these plants on one hand, and on the resistance level / immune system of human beings on the other.

Abstract. A set of rapid near infrared spectroscopy analysis methods were developed for the content determination of Polygonum perfoliatum L.. Investigate the relation between climate and proportion of the active ingredient content. Models were established with partial least squares (PLS) algorithm. The correlation coefficients between predicted value and measured value of the three calibration models are above 0.9 which indicated that there have no differences between NIR and UV in content determination. NIR has a broad prospect of application in the quality control of Chinese traditional medicine. Proportion of polyphenol and flavone is from 1.71 to 2.26. Combined with the local climate analysis shows: Tropical or subtropical humid monsoon climate conducive to the accumulation of polyphenol ingredient, large temperature difference between day and night conducive to the accumulation of flavone ingredient． The result can provide reference for the cropping of Polygonum perfoliatumL.. IntroductionPolygonum perfoliatum L. (PPL) is the aerial parts of the polygonaceae plant which was recorded in "all diseases rejuvenation" written by Tingxian Gong in Ming Dynasty(1587) [1] . Its nature and flavors are plain, sour and bitter. It can induce diuresis for removing edema, cleanup heat detoxifcation, relieve a cough. Modern pharmacological studies have shown that PPL have activities in anti-inflammatory and anti-tumor effect. Owing to its curative effects, it had been recorded in the 2010 and 2015 edition of the Chinese pharmacopoeia (ChP) as a new variety which is payed extensive attentionin in recent years [2] . PPL is widely distributed in China. Accordingly, the quality of the herbal raw materials fluctuates, owing to varying ecological environments [3][4][5] . For the efficacy of Traditional Chinese Medicine (TCM) are based on a certain ratio of multi-component, so study the ratio of active components and its relationship with climate are very important [6,7] . Near-infrared spectroscopy (NIR) technology combined with chemometric can directly analysis of multi-components in a few seconds no matter the opaque samples are granulated, paste or solid and needn't pretreated of the sample. AS a high-speed, non-destructive technique, it has showed vast prospect in TCM research [8][9][10][11][12] . This study aimed to establish a fast determination of multi-component method by NIR. Materials and Methods Equipment and MaterialsNIR analyzer (Nicolet 6700, Thermo Scientific) with an InGaAs detector was used for NIR spectra collection and analysis; UV-visible spectrophotometer (UV 1200, Shanghai Precision & Scientific Instrument Co., Ltd.) was used to detect the content of PPL; gallic acid (110831-200302, Sample preparationThe samples were milled into powder with a grinder. The final powder samples were prepared by passing the ground powder through a 50-mesh sieve. To ensure that moisture was not an interfering factor, all samples were dried in an oven at 40°C for 12 h, placed in the dryer alternate. NIR spectra collection5g po...
