“…Both leaf and stem showed presence of phenols and flavonoids and it is known that plants rich in phenols and flavonoids show good antioxidant activity and plants rich in antioxidant activity show good pharmacological or biological activity (Chanda and Dave, 2009). Similar phytochemical analysis is reported by Tang et al, (2018) for Psychotria rubra root, stem and leaves; Kanthale and Biradar (2017) for Helicteres isora fruits; Trianthema portulacastrum (Pande et al, 2018).…”

Phyla nodiflora L. Greene (Verbenaceae) is a medicinal plant commonly known as Ratoliya in Gujarati and Bhujokra in Hindi. Traditionally it is used to cure many diseases like diarrhoea, ulcers, asthma, bronchitis, knee joint pain, gonorrhoea and also there are many reported pharmacological activities like antibacterial, antifungal, antiinflammation, antiulcer, antidiuretic, etc. Thus, it is very essential to lay down quality control parameters so that the therapeutic efficacy of the plant can be maintained. In order to achieve this, in the present work, Phyla nodiflora leaf and stem were evaluated for their physicochemical, phytochemical and pharmacognostic parameters. For phytochemical analysis, different phytoconstituents like saponins, tannins, glycosides, phenols, triterpenes, flavonoids, steroids, etc. were evaluated. For physicochemical analysis, different ash values, extractive values and loss on drying was determined following all standard procedures. Both leaf and stem were rich in phenols, flavonoids and alkaloids; however, leaf had steroids and stem had saponins in maximum amount. The ash values were more in leaf than in stem while loss on drying was almost same (> 10%) in both the parts. Likewise, extractive value was maximum in methanol and minimum in petroleum ether. The diagnostic characters laid down in this study will be helpful for its correct identification and ensure its purity. They are the most simple, easy and cheapest quality control parameters.

“…Different solvent extracts of different parts of plant analysis revealed the presence of various types of phytoconstituents in different amounts that help in the selection of specific extract for isolating the active principle [48]. The pharmacological activity studies are not part specific of medicinal plant rather all organs are important and evaluated for various therapeutic efficacies of plant such as leaf of Ageratum conyzoids and Homalium ceylanium [1,7,22], root of Argyreia pilosa [45], stem of Psychotria rubra and Acacia auriculiformis [38,50,56], bark of Chloroxylon swietenia [14], fruit of Benincasa Hispida [37], flower of Woodfordia fruticosa [5], seed of Aegle marmelos [42], aerial parts of Heracleum persicum and Achyranthes aspera [54,63], rhizome [23] and pseudobulbs of Coelogyne cristata [43].…”

The present study about Trianthema portulacastrum (Linn.), family Aizoaceae, is an effort to evaluate physicochemical parameters, phytochemical screening, pharmacognostic properties of stem, root, leaf and seed and preparedness of different extracts by solvent system of wide-range polarity. Physicochemical analysis includes loss on dryness, total ash value, water-soluble ash value, acid-insoluble ash value, pH analysis, fluorescence study and extractive values in different solvent systems. All the parts of the plant showed loss on dryness in the range of 2 ± 0.69 to 7 ± 0.73. Foreign organic matters recorded in different parts of plant were in the range of 0.8 ± 0.045 to 2.0 ± 0.081. The total ash values were determined from 9.59 ± 1.87 to 15.54 ± 1.21% (w/w). The water-soluble ash values were from 7.5 ± 1.10 to 9.38 ± 1.54% (w/w), and acid-insoluble ash values were from 0.92 ± 0.84 to 4.19 ± 0.75% (w/w). Macroscopic, powder microscopy, fluorescence studies, extractive values, different properties of extracts and phytochemical screening studies were completed by a series of standard tests. The parameters evaluated under this study will safeguard the authenticity and efficacy of crude drug and provide referential information in distinguishing the drug from its adulterants. The observations of studied parameters will be useful and helpful in setting diagnostic indices for identification and preparation of monograph of this plant and in differentiating root, stem, leaf and seed of this species from closely related species of same genus and family.

“…The therapeutic efficacy was not limited to a specific plant part; every plant part displays a pharmacological activity. Henceforth, the pharmacognostic studies of different plant parts have been performed for different plant organs [63], such as aerial parts, flower, fruit, leaf root, and stem [64][65][66][67][68][69][70][71]. The fatty acid profile of C. conglomeratus showed the presence of palmitic, linoleic, heptadecanoic, oleic, myristic, arachidonic, lignoceric, and stearic acid.…”

Cyperaceae are a plant family of grass-like monocots, comprising 5600 species with a cosmopolitan distribution in temperate and tropical regions. Phytochemically, Cyperus is one of the most promising health supplementing genera of the Cyperaceae family, housing ≈950 species, with Cyperus rotundus L. being the most reported species in pharmacological studies. The traditional uses of Cyperus spp. have been reported against various diseases, viz., gastrointestinal and respiratory affections, blood disorders, menstrual irregularities, and inflammatory diseases. Cyperus spp. are known to contain a plethora of bioactive compounds such as α-cyperone, α-corymbolol, α-pinene, caryophyllene oxide, cyperotundone, germacrene D, mustakone, and zierone, which impart pharmacological properties to its extract. Therefore, Cyperus sp. extracts were preclinically studied and reported to possess antioxidant, anti-inflammatory, antimicrobial, anticancer, neuroprotective, antidepressive, antiarthritic, antiobesity, vasodilator, spasmolytic, bronchodilator, and estrogenic biofunctionalities. Nonetheless, conclusive evidence is still sparse regarding its clinical applications on human diseases. Further studies focused on toxicity data and risk assessment are needed to elucidate its safe and effective application. Moreover, detailed structure-activity studies also need time to explore the candidature of Cyperus-derived phytochemicals as upcoming drugs in pharmaceuticals.
