Abstract
Swertia chirayita is used as a traditional medicinal plant due to its pharmacological activities, including antioxidant, antidiabetic, antimicrobial, and cytotoxic. This study was aimed to evaluate the therapeutic efficacy of newly synthesized nanosuspensions from Swertia chirayita through nanotechnology for enhanced bioactivities. Biochemical characterization was carried out through spectroscopic analyses of HPLC and FTIR. Results revealed that extract contained higher TPCs (569.6 ± 7.8 mg GAE/100 g)) and TFCs (368.5 ± 9.39 mg CE/100 g) than S. chirayita nanosuspension, TPCs (500.6 ± 7.8 500.6 ± 7.8 mg GAE/100 g) and TFCs (229.5± 3.85 mg CE/100 g). Antioxidant activity was evaluated through DPPH scavenging assay, and nanosuspension exhibited a lower DPPH free radical scavenging potential (06 ±3.61) than extract (28.9± 3.85). Anti-dabetic potential was assessed throughα-amylase inhibition and anti-glycation assays. Extract showed higher (41.4%) antiglycation potential than 35.85% nanosuspension and 19.5% α-amylase inhibitory potential than 5% nanosuspension. Biofilm inhibition activity against E. coli was higher in nanosuspension (69.12%) than extract (62.08%). The extract showed high cytotoxicity potential (51.86%) than nanosuspension (33.63%). These nanosuspensions possessed enhanced bioactivities for therapeutic applications could be explored further for the development of new drugs.

Abstract
The search for novel heterocyclic compounds with a natural product skeleton as potent enzyme inhibitors against clinical hits is our prime concern in this study. Here, a simple and facile two-step strategy has been designed to synthesize a series of novel coumarin-based dihydropyranochromenes (12a-12m) in a basic moiety. The synthesized compounds were thus characterized through spectroscopic techniques and screened for inhibition potency against the cytosolic hCA II isoform and β-glucuronidase. Few of these compounds were potent inhibitors of hCA II and β-glucuronidase with varying IC50 values ranging from 4.55 ± 0.22 to 21.77 ± 3.32 μM and 440.1 ± 1.17 to 971.3 ± 0.05 μM, respectively. Among the stream of synthesized compounds, 12e and 12i were the most potent inhibitors of β-glucuronidase, while 12h, 12i, and 12j showed greater potency against hCA II. In silico docking studies illustrated the significance of substituted groups on the pyranochromene skeleton and binding pattern of these highly potent compounds inside enzyme pockets.

Abstract
Swertia chirata Buch.-Ham. ex C.B. Clarke is an important medicinal plant used in various herbal formulations as it shows significant biological activities such as hepatoprotective, hypoglycemic, anti-inflammatory, antimalarial, antioxidant and anti-parkinson. C-glucosyl xanthone glycoside (mangiferin) is known as bio-marker compound of genus Swertia L. Development of efficient extraction methods of C-glucosyl xanthone mangiferin from Swertia chirata was attempted by optimizing the pre-harvest, post-harvest and extraction techniques by full factorial design. Firstly, a full factorial design was implemented to evaluate the single and interactive effects of pre-harvest (growth stage and plant part), post-harvest (drying condition and storage periods) followed by selection of best extraction technique such as heat reflux extraction (HRE), microwave assisted extraction (MAE) and ultrasound assistant extraction (UAE) at different solvent types on mangiferin yield. HPTLC and HPLC techniques were used for the determination of mangiferin content in extracts generated from different plant samples. In addition, anti-oxidant and anti-diabetic properties were determined by using DPPH assay and percentage inhibition of α‑amylase enzyme. Substantial variation of mangiferin yield, ranged from 1.46 to 4.86% was observed, depending on the growth stage, plant part, drying condition, storage periods and extraction method. Results showed that drying of the leaves of Swertia chirata in the shade harvested at budding stage and stored for not more than 1 month was recommended for obtaining a higher mangiferin yield. Among different extraction techniques, MAE and UAE in 50% aqueous ethanol solvent were found to be efficient and cost-effective with better yield of mangiferin (4.82% and 4.86%, respectively) as compared to HRE (4.14%). Highest DPPH activity and percentage inhibition of α‑amylase was observed in the aqueous ethanol extract of S. chirata leaves harvested at bud-stage of plant followed by flowering stage. The study shows that optimization of various factors by full factorial design was found to be an effective procedure to improve mangiferin yield from Swertia chirata and can be used for extraction of mangiferin.

Abstract
Diabetes is a common chronic disease where therapeutics innovation is much needed. The search for novel antidiabetic molecules can be greatly facilitated by high throughput metabolomic characterization of herbal medicines. Cassia auriculata is a shrub used in Ayurvedic medicine and native to India and Sri Lanka. While C. auriculata has been used as a medicinal herb in diabetes, the molecular evidence for its antidiabetic medicinal potentials and components needs to be established. Moreover, the phytocomposition of the various plant parts is not fully known. We report a comprehensive metabolomic gas chromatography mass spectrometry study of the C. auriculata plant parts, including the leaf, flower, and bud. We identified a total of 102 primary and secondary metabolites in seven chemical groups, including amino acids (AA), carboxylic acids, nucleosides, fatty acids, among others. Interestingly, plant parts differed in their metabolomic signatures. While in the flowers and leaves nine and six AA were identified, respectively, no AA was detected in the buds. Some of the identified compounds have been previously noted for their antidiabetic, hypoglycemic, and hypolipidemic bioactivities. These findings offer a concrete metabolomic basis on the phytocomposition of individual C. auriculata plant parts. These omics data call for future research on the function of the identified compounds, and clinical studies to further evaluate their antidiabetic potentials and mechanisms of action in the clinic. Finally, we note that plant omics research offers an important avenue to inform, verify, and strengthen the evidentiary base and clinical testing of herbs with medicinal potentials.

Abstract
Diabetes mellitus is referred as common metabolic abnormalities characterized as hyperglycemia, mainly caused due to insufficient production of insulin at cellular level or/and defects in insulin action. Such an endocrine disorder is responsible for serious health problems and its worldwide prevalence is rapidly increasing. Common management of diabetes by oral administration of drugs without creating any side effects is still considered a challenging task and increasing cost of conventional medicine in developing countries is another matter of concern. To address these issues, traditional preparations of herbal plant extracts in the form of medicines already gained immense attention. Swertia chirayita is one among such plants which is known for its hypoglycemic potential. Numerous chemical constituents with promising pharmacological properties have been identified from such plant extracts but still, such compounds have not been well characterized, specifically against human application. Hence, more research efforts are necessitated to understand exact mechanism of such compounds and to develop overall safety of such plant formulations. Present review clearly represents antidiabetic properties of Swertia chirayita extract, strategies to be taken to strengthen its safety application on humans and biotechnological interventions that ensure conservation of such endangered species to promote its future application in modern medicine.

Abstract
The emergence of disease and dearth of effective pharmacological agents on most therapeutic fronts, constitutes a major threat to global public health and man's existence. Consequently, this has created an exigency in the search for new drugs with improved clinical utility or means of potentiating available ones. To this end, accumulating empirical evidence supports molecular target therapy as a plausible egress and, β-glucuronidase (βGLU) - a lysosomal acid hydrolase responsible for the catalytic deconjugation of β-d-glucuronides has emerged as a viable molecular target for several therapeutic applications. The enzyme's activity level in body fluids is also deemed a potential biomarker for the diagnosis of some pathological conditions. Moreover, due to its role in colon carcinogenesis and certain drug-induced dose-limiting toxicities, the development of potent inhibitors of βGLU in human intestinal microbiota has aroused increased attention over the years. Nevertheless, although our literature survey revealed both natural products and synthetic scaffolds as potential inhibitors of the enzyme, only few of these have found clinical utility, albeit with moderate to poor pharmacokinetic profile. Hence, in this review we present a compendium of exploits in the present millennium directed towards the inhibition of βGLU. The aim is to proffer a platform on which new scaffolds can be modelled for improved βGLU inhibitory potency and the development of new therapeutic agents in consequential.

Abstract
The inhibition of the β-glucuronidase released from gut bacteria is associated with specific health-related benefits. Though a number of β-glucuronidase inhibition assays are currently in use, none of them can directly measure the relevant activity of each single constituent in a complex mixture, without prior separation and tedious isolation of the pure compounds. Thus, the hyphenation of the high performance thin layer chromatography (HPTLC) technique with a β-glucuronidase inhibition assay was investigated and successfully demonstrated for the first time. A colorimetric as well as fluorometric detection of the inhibitors was achieved using 5-bromo-4-chloro-3-indolyl-β-D-glucuronide as a substrate. Hence, β-glucuronidase inhibitors were detected as bright zones against an indigo blue or fluorescent background. The established method was optimized and validated employing the well-known inhibitor d-saccharic acid 1,4-lactone monohydrate. As proof of concept, the suitability of the new workflow was verified through analysis of two botanical extracts, Primula boveana and silymarin flavonolignans from Silybum marianum fruits. The found inhibitors were identified by spectroscopic methods; one of them, 3ʹ-O-(β-galactopyranosyl)-flavone, is here described as a newly isolated natural compound. The new hyphenation HPTLC-UV/Vis/FLD-β-glucuronidase inhibition assay-HRMS covers four orthogonal dimensions, i.e. separation, spectral detection, biochemical activity and structural characterization, in a highly targeted time- and material-saving workflow for analysis of complex or costly mixtures. Coupling of HPTLC to the β-glucuronidase inhibition assay is demonstrated. Colorimetric and fluorometric detection of the inhibition was given. A new β-glucuronidase inhibiting flavonoid in P. boveana was elucidated. HPTLC-HRMS analysis of other β-glucuronidase inhibitors is shown for silymarin. Analysis of rare plants (low extract amount) is possible with the new planar assay.

Abstract
RATIONALE Piper betle leaf, used as masticatory in South Asia, is also medicinally important. OBJECTIVE This work was done to analyze phytochemical composition of two solvent fractions (chloroform and ethyl acetate) of the aqueous extracts obtained from eight varieties of P. betle leaves and to identify the active components against β-glucuronidase by chemometric analysis. RESULTS Twenty-four phenolic compounds, in addition to different organic acids, fatty acids, amino acids, sugars, and polyols, were identified from the solvent fractions. The extracts inhibited the enzyme β-glucuronidase. Piceatannol was the most active constituent against the enzyme (activity 12 times higher than that of silymarin), Chlorogenic acid also inhibited β-glucuronidase (activity 4.4 times higher when compared to silymarin). 2,2'-Diphenyl-1-picrylhydrazyl and superoxide free radical scavenging activities of both the fractions of eight varieties of P. betle leaf extracts showed very strong antioxidant potentiality. CONCLUSION The findings validated some medicinal properties of the said leaves. PRACTICAL APPLICATIONS Edible leaves of Piper betle are medicinally and economically important. Leaves of different local varieties are reported to be used for the treatment of different diseases. The leaves have many biological properties, hepatoprotection being one of them. A large number of rural population is economically dependent on the cultivation of betel vine. But with a rapid change in lifestyle, the chewing habit of P. betle is decreasing ultimately affecting the livelihood of farmers dependent on betel cultivation. Knowledge on β-glucuronidase inhibitory activity and the mechanism for hepatoprotection of different P. betle varieties may validate the medicinal properties of betel, which would increase consumption of these leaves.
