The effect of various solvent extracts ofGelidiella acerosaon acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) activities was investigated. AChE and BuChE inhibitory activities were analyzed by spectrophotometric method. Phytochemical screening of the compounds present in the solvent extracts was done qualitatively. Characterization of the compounds present in the benzene extract ofG. acerosawas done by GC-MS analysis. The results showed that, at 487.80 μg/mL, benzene extract showed significant (P<0.05) inhibitory activity against both AChE and BuChE with the percentage of inhibition54.18±5.65% (IC50 = 434.61±26.53 μg/mL) and78.43±0% (IC50 = 163.01±85.35 μg/mL), respectively. The mode of inhibition exhibited by benzene extract against the AChE and BuChE was found to be competitive and uncompetitive type of inhibition, respectively. Preliminary phytochemical analysis coupled with GC-MS illustrates that the benzene extract possesses high amount of terpenoids, which could be the reason for potential cholinesterase inhibitory activity.

Carum carvi (Caraway) is a member of Apiaceae family which originated in Asia. Due to its economic importance, it is widely cultivated. Caraway is the only annual species, commonly present in arable land, moist meadows and on low lands to mountains. Caraway has different applications in pharmaceutical and food industries. Phytochemical screening of different medicinal plants is helpful in identifying new sources of industrially and therapeutically important compounds. In this study, Caraway obtained from forest surrounding the village Goherman, Lahaul and Spiti, Himachal Pradesh (India) was used. Seed extract of caraway extracted in methanol (MSE) and distilled water (WSE) was used for phytochemical analysis to determine the constituents of caraway seeds. Further, caraway seeds extract was checked for antibacterial activity [Staphylococcus aureus (ATCC 6538), Salmonella typhimurium (NCTC 74), Escherichia coli (ATCC 25922) and Staphylococcus epidermidis (ATCC 12228)], antioxidant activity and acid neutralizing activity. After analysing the results, it can be said that caraway seeds possess many medicinal properties and it can be used in enhancing human health.

Acacia mearnsii (Fabaceae) contains acacia polyphenols, which are a complex mixture of proanthocyanidins that are mainly composed of 5-deoxycatechin units. In this study, an aqueous extract of A. mearnsii bark was fractionated and the α-amylase inhibitory activity of each fraction was evaluated. The 13C NMR and MS data and the pyrolysis products obtained from the active and inactive fractions were compared. The spectroscopic results clearly indicated that fractions with strong inhibitory activity contained proanthocyanidin oligomers with catechol-type B-rings rather than pyrogallol-type B-rings. HPLC analysis of the pyrolysis products showed peaks for pyrocatechol were only observed in the mixtures obtained from the fractions with high inhibitory activities. In addition, (+)-pinitol was isolated as a major polyol of the extract at a level comparable with that of sucrose.

The present study was carried out to investigate the phytochemical profile of Incarvillea emodi and Malva neglecta. The two plants were screened for the presence of nine different classes of bioactive compounds. The qualitative tests were performed on the aerial and underground parts of the selected plants to relate the presence of phytochemicals with bioactivities of the plants. The selected plant material was extracted with three different solvents. These extracts were then subjected to phytochemical screening and the presence of various phytochemicals was confirmed by different standard confirmatory tests. Most of the phytochemicals were found to be present. Results showed that the underground parts of Incarvillea emodi contain comparatively greater number of phytochemicals than the aerial parts. Whereas, in case of Malva neglecta the aerial parts showed more positive results than the underground parts. The current study offers proof for the presence of important bioactive compounds in the studied plants and recommends isolation and characterization of these compounds in the future.

Ayurveda, the oldest paradigm of health and healing known to the world, grew out of the Rishi tradition. The medical and research community is constantly seeking for new natural agents. Sphaeranthus indicus Linn. (Gorakhmundi, Family: Asteraceae), is widely used in Ayurvedic system of medicine to treat various diseases. The present investigation was designed to perform physicochemical and phytochemical analysis with HPTLC fingerprints of Sphaeranthus indicus (leave, flower, and stem) to establish the standard parameters of this herb. Different analytical parameters like extractive values, total ash, acid insoluble ash and water-soluble ash, moisture content, pH values of different parts of the drug were performed. Preliminary phytochemical screening was done to detect and quantify different active constituents such as alkaloids, flavanoids, proteins and total poly phenol using various analytical methods. Our preliminary data of phytochemical screening of the extracts revealed the presence of steroids, carbohydrates, proteins, terpenoid, flavonoid, tannins, alkaloids, resin and saponin. In the current study we established the HPTLC fingerprint of the extract using phytochemical standards. We believe that our study provides a substantial data for identification, purification, standardization, and phytochemical characterization of novel therapeutic compounds that can be used potential drug to combat various diseases for betterment of mankind.

Leave extract were prepared with methanol by Soxhlet apparatus. Total phenolic contents were determined by Folin-Ciocalteus reagent method.  Alkaloid, phenol, flavonoid, terpenoid, glycoside, saponin and steroid were detected in Paederiafoetida but high concentration in terpenoid and steroid.  Saponin was absent inBlumeopsisflava. Steroid was also not found in Blumeopsisflava and Clerodendrumsiphonanthes. The  total  phenolic contents  of  the methanol  e¬xtract  of P. foetida, C. siphonanthes and B. flava  in terms of Gallic acid  equivalent were 138.33 ± 6.41, 131.67 ± 5.77 and 71.25 ± 7.60 mg/g  of  extract   respectively.  Paederiafoetida   exhibited highest total phenolic contents then followed by C. siphonanthes and B. flava. It is evident that Paederiafoetidahas highest therapeutic efficacy. The present study indicates that these plants are of therapeutic potential due to the presence of various phytochemicals.

Six aporphine alkaloids (1–6) were isolated from Artabotrys spinosus roots based on bioassay-guided fraction and chromatographic methods. All isolated alkaloids were evaluated for their cholinesterase (ChEs) inhibitory activities, in which compounds 4 and 6 exhibited the highest activity toward butyrylcholinesterase (BChE) and acetylcholinesterase (AChE), respectively. The Lineweaver-Burk plots suggested that 4 and 6 were mixed mode inhibitors toward BChE and AChE enzymes, respectively. In addition, the experimental results were also confirmed by molecular docking analysis. This information can help in designing a new inhibitor in the class of aporphine alkaloids in against Alzheimer's disease.
