Objective: The fruit of Terminalia bellirica Roxb. or Baheda (Family Combretaceae) is an extensively used herb in traditional medicines. The fruit as a whole or a part of it is used in traditional healing. Fruit has two major parts, namely, pericarp and seed, pericarp, in turn, consists of epicarp, mesocarp, and endocarp. Ayurvedic compound formulations such as Triphala and Pathyadi contain pericarp of the fruit. The present study is aiming a comparative phytochemical investigation of fruit parts such as epicarp, mesocarp, and seed along with the whole fruit. Methods: The study included physicochemical evaluation, phytochemical screening, biochemical assay, and thin-layer chromatography profile of the inner parts of the fruit. Results: The study shows that seeds are rich in essential oil (13.25%), but very poor quantity of phenolics (0.65 gallic acid equivalent [GAE]) and flavonoids (0.77 quercetin equivalent [QE]) is present compared to epicarp (139.05 GAE and 141.26 QE) and mesocarp (135.23 GAE and 142.05 QE). In addition to that, qualitative phytochemical screening revealed that seeds are void of steroids and lignans. Conclusion: The study concluded that seeds are less important in respect to the presence of secondary metabolites. It may also be concluded that mesocarp and epicarp are holding major responsibilities of therapeutic values imposed on the fruit.

Extracts of the leaves, stem, roots, and seeds of <em>Mitracarpus scaber</em> plants have been thoroughly investigated in an attempt to determine their phytochemical and antioxidant activities.<em> </em>Phytochemical screening carried out by thin-layer chromatography (TLC) revealed the presence of several secondary metabolites in all the selective extracts of the plant. The levels of phenolic compounds showed that the leaves of <em>M. Scaber</em> are the richest in polyphenols with an average value of 488.291 ± 1.205 μg GAE/g (microgram of gallic acid equivalent per gram of the dry matter of the powdered plant). The total flavonoid assay revealed a high content in the leaves (1.624 ± 0.032 %). Also, studies of the antioxidant activities by DPPH<sup>● </sup>(2,2-diphenyl-1'-picrylhydrazyl) method showed a significant effect compared to vitamin C (96.62 %). The percentages of inhibition are respectively 89.82 % and 82.3 % for ethyl acetate extracts of the leaves and seeds. Furthermore, the inhibitory percentages of n-butanol in the leaves and seeds are 90.57 % and 83.67 %, respectively. Calculated IC<sub>50</sub> showed that the n-butanol fraction of the seeds exhibited the highest activity with an IC<sub>50</sub> of 0.293 mg/mL less than ascorbic acid with an IC<sub>50</sub> of 0.387 mg/mL.

Agrimonia asiatica is a perennial plant with deep green color and covered with soft hairs and has a slightly aromatic odor. This genus Agrimonia has been used in traditional medicines of China, Greece, and European countries. It was mainly used as a haemostatic, a tonic for asthenia, and an astringent for diarrhea. Agrimony is part of the division Magnoliophyta; class is represented by order Rosales, family Rosaceae, of the genus Agrimonia. Family Rosaceae—or pink eels—is one of the largest families of flowering plants, including about 100 genera and 3000 species. Rosaceae is common in almost all areas of the globe where flowering plants can grow, but most of them are concentrated in the temperate and subtropical zones of the Northern Hemisphere. Phytochemical investigation on ethanolic extract of A. asiatica led to isolation of four flavonoid derivatives (kaempferol-3-glycoside, quercetin-3-O-α-arabinofuranosyl-β-D-galactopyranoside, 3-O-kaempherol 2,3-di-O-acetyl-4-O-(cis-p-coumaroyl)-6-O-(trans-p-coumaroyl)-β-D-glucosopyranoside, and catechin) alongside of sucrose. All the extracts, fractions, and isolated compounds were tested for antimicrobial and antiplasmodial activities. We also studied the chemical composition of essential oil obtained from the aerial part of A. asiatica. The essential oil constituents from the aerial part of A. asiatica were obtained using a steam-distillation method in wild growing conditions in Kazakhstan. The essential oil extracted from the aerial part of the plant was analyzed by gas chromatography-mass spectroscopy and its major components amounting to 100% were found to be β-selinene (36.370%), α-panasinsene (21.720%), hexadecanoic acid (7.839%), and 1,2-nonadiene (6.199%). Neither the extract nor the isolated compounds showed antimicrobial and antiplasmodial activities.

The compounds in Ginger (Zingiber officinale-Roscoe) essential oil provenience China and wild oregano (Origanum vulgare) essential oil of Romanian origin were identified by GC/MS and their antioxidant and antifungal properties were evaluated. Wild oregano oil was characterized by high content of oxygenated monoterpenes hydrocarbons (84.05%) of which carvacrol was the most abundant (73.85%) followed by b-linalool (3.46%) and thymol (2.29%). Ginger oil had a higher content of sesquiterpene hydrocarbons including zingiberene (31.47%), b-sesquiphellandrene (13.76%), a-curcumene (10.41%), a-farnesene (8.31%) and b-bisabolene (7.55%) but a lower content of oxygenated monoterpenes (7.97%). The high content of oxygenated monoterpens of wild oregano oil is in accordance with total content of polyphenols determined by the Folin�Ciocalteu method (6.71�0.73 mg of gallic acid equivalent per g oil). Ginger oil had only 1.34�0.22 mg gallic acid equivalent per g oil. Wild oregano oils exhibited appreciable in vitro antioxidant activity as assessed by 2, 2`-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging and 2,2�-azino-bis (3 ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS). The sample concentration required to scavenge 50% of the DPPH free radicals was 0.76�0.13 mg/mL for wild oregano oil compared to 20.22�2.12 mg/mL for ginger oil. Also, wild oregano oils showed significant inhibitory activity against selected pathogenic fungi (Fusarium oxysporum, Aspergillus flavus and Penicillium expansum). 1�L of oregano oil is sufficient for almost 75% growth inhibition of Aspergillus flavus compared to ginger oil which shows antifungal activity at 240�L for 78% growth inhibition. It can be concluded that wild oregano oil could be used as food preservative in some food products in which Fusarium oxysporum, Aspergillus flavus and Penicillium expansum could grow and have potential to produce health hazards mycotoxines.

Background: Vriddhi is one of the Rasayana herbs in Ayurveda broadly used in vitality, strengthening Ayurvedic formulations. To fulfill steeply increased demand and declined supply, tubers have been collected in destructive manner resulting in reduced plant population and pushing the plant in Red list of IUCN endangered species. However, manufacturers are using substitutes and other substandard drugs leading to adulteration which puts the importance of therapeutically rich herbal plants at stake. Lack of chemical markers is the main inability of regulatory authorities for not taking any action against this adulteration. Objective: Isolation of chemical marker of plant that can be used as a reference compound for identification of unauthorized substitution. Methods: Preliminary phytochemical screening of methanolic and toluene extract of H. intermedia D. Don was done using standard methods followed by column chromatography for the isolation of phytoconstituents. A total of 3004 fractions were collected with Thin Layer Chromatography (TLC) profiling and different fractions were pooled. A single compound was isolated and confirmed by chemical test, melting point, spectral analysis and compared with the literature. Results: Phytochemical screening of extracts shows the presence of alkaloids, carbohydrates, steroids, terpenoids, flavonoids, tannins and phenolics. A pure white crystalline powder was isolated by column chromatography which was characterized as 3,5-dimethoxy-4- hydroxycinnamic acid (Sinapic acid) with the help of IR and Mass spectroscopy. Conclusion: This is the first report of Sinapic acid as a novel compound from Vriddhi, Habenaria genus and Orchidaceae family. It can be used as a marker for the identification of unauthorized substitution and adulteration claiming the use of Vriddhi.
