Source-dependent variation in phenolic compounds and antioxidant activities of Prinsepia utilis Royle fruits.

Prinsepia utilis, a wild-growing Himalayan shrub, is a good source of phytoceuticals, cosmeceuticals, and antioxidants. The present study is an attempt to investigate the effect of altitude and edaphic factors on phenolics and antioxidant activity in fruit pulp of Prinsepia utilis. The ripened fruits and soil samples were collected for detailed investigation. The fruits (pulp) were extracted in methanol for analyzing total phenolics and antioxidant activity using a spectrophotometric method and phenolic compounds by high-performance liquid chromatography (HPLC). Similarly, standard methods for soil analysis were used. Results reveal that altitude negatively correlated with total phenolics and flavonoid contents determined by a spectrophotometric method and with specific phenolic compounds determined by HPLC. For instance, Dwarahat population (PU-1) at lower altitude (1400 m asl) exhibited higher values of total phenolics and flavonoids, while total tannin was higher at Nainital (PU-6) population (2000 m asl). The antioxidant activity measured by 2, 2-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) was found higher in Narayan Ashram (PU-9) population (2750 m asl), while ferric reducing antioxidant power (FRAP) was significantly higher in Badechena (PU-2) population (1600 m asl). Soil nutrients (edaphic factors) showed a good correlation among measured parameters. Neighbor-joining and principal component analysis identified phenolics and antioxidant-rich populations that can be utilized for collection of fruits from these populations.

Food and Antioxidant Supplements with Therapeutic Properties of Morchella esculenta (Ascomycetes): A Review.

Morchella esculenta, commonly known as yellow morels, is an edible and medicinal mushroom popular worldwide for its unique flavor and culinary purposes. The traditional medical system effectively uses morels against infertility, fatigue, cancer, muscular pain, cough, and cold. The M. esculenta possesses many health-promoting nutritional components such as mono and polyunsaturated fatty acids, polyphenols, protein hydrolysates, vitamins, amino acids and minerals. The potential medicinal properties of morels is due to polysaccharides (galactomannan, chitin, ß-glucans, and ß-1,3-1,6-glucan) present that has high economic importance worldwide. Polysaccharides present possess a broad spectrum of biological activities such as anti-cancer, anti-inflammatory, anti-microbial, anti-diabetic, and antioxidant. However, the toxicity and clinical trials to prove its safety and efficacy for medicinal uses are yet to be evaluated. Moreover, the separation, purification, identification, and structural elucidation of active compounds responsible for the unique flavors and biological activities are still lacking in M. esculenta. The available information provides a new base for future perspectives. It highlights the need for further studies of this potent medicinal mushroom species as a source of beneficial therapeutic drugs and nutraceutical supplements.

Predicting phytochemical diversity of medicinal and aromatic plants (MAPs) across eco-climatic zones and elevation in Uttarakhand using Generalized Additive Model.

The present study uses a systematic approach to explore the phytochemical composition of medicinal plants from Uttarakhand, Western Himalaya. The phytochemical composition of medicinal plants was analyzed based on (i) the presence of different chemical groups and (ii) bioactive compounds. The Generalized Additive Model (GAM) analysis was used to predict the occurrence of chemical groups and active compounds across different eco-climatic zones and the elevation in Uttarakhand. A total of 789 medicinal plants represented by 144 taxonomic families were screened to explore the phytochemical diversity of the medicinal plants of Uttarakhand. These medicinal plant species are signified in different life forms such as herbs (58.86%), shrubs (18.24%), trees (17.48%), ferns (2.38%), and climbers (2.13%). The probability of occurrence of the chemical groups found in tropical, sub-tropical, and warm temperate eco-climatic zones, whereas active compounds have a high Probability towards alpine, sub-alpine, and cool temperate zones. The GAM predicted that the occurrence of species with active compounds was declining significantly (p < 0.01), while total active compounds increased across elevation (1000 m). While the occurrence of species with the chemical group increased, total chemical groups were indicated to decline with increasing elevation from 1000 m (p < 0.000). The current study is overwhelmed to predict the distribution of phytochemicals in different eco-climatic zones and elevations using secondary information, which offers to discover bioactive compounds of the species occurring in the different eco-climatic habitats of the region and setting the priority of conservation concerns. However, the study encourages the various commercial sectors, such as pharmaceutical, nutraceutical, chemical, food, and cosmetics, to utilize unexplored species. In addition, the study suggests that prioritizing eco-climatic zones and elevation based on phytochemical diversity should be a factor of concern in the Himalayan region, especially under the climate change scenario.

Comparative assessment of morphological, physiological and phytochemical attributes of cultivated Valeriana jatamansi Jones in Uttarakhand, West Himalaya.

Medicinal plants are global sources of herbal products, drugs, and cosmetics. They are disappearing rapidly due to anthropogenic pressure, overexploitation, unsustainable harvesting, lack of knowledge on cultivation, and the availability of quality plating materials. In this context, standardized in-vitro propagation protocol was followed to produce Valeriana jatamansi Jones, and transferred in two locations at Kosi-Katarmal (GBP) Almora (1200 masl) and Sri Narayan Ashram (SNA) Pithoragarh (Altitude 2750 masl), Uttarakhand. Over the three years of growth, plants were gathered from both locations for determining biochemical and physiological parameters, and growth performance. The plants growing at Sri Narayan Ashram (SNA) showed considerably (p < 0.05) higher amounts of polyphenolics, antioxidant activities, and phenolic compounds. Similarly, physiological parameters (transpiration 0.004 mol m-2 s-1; photosynthesis 8.20 µmol m-2 s-1; stomatal conductance 0.24 mol m-2 s-1), plant growth performance (leaves number 40, roots number 30, root length 14 cm) and soil attributes (total nitrogen 9.30; potassium 0.025; phosphorus 0.34 mg/g, respectively) were found best in the SNA as compared to GBP. In addition, moderate polar solvent (i.e., acetonitrile and methanol) was found suitable for extracting higher bioactive constituents from plants. The findings from this study revealed that large-scale cultivation of V. jatamansi should promote at higher elevation areas such as Sri Narayan Ashram to harness the maximum potential of the species. Such a protective approach with the right interventions will be helpful to provide livelihood security to the local populace along with quality material for commercial cultivation. This can fulfill the demand through regular supply of raw material to the industries and simultaneously promote their conservation.

Saturated and Polyunsaturated Fatty Acids Rich Populations of Prinsepia utilis Royle in Western Himalaya.

The study aims to identify the fatty acid composition in Prinsepia utilis seeds collected from diverse populations of Western Himalaya, India. The seeds contained higher saturated fatty acid (SFA-43.09%; Average of all populations) followed by polyunsaturated fatty acid (PUFA - 29.57%) and monounsaturated fatty acid (MUFA - 25.53%), however variations among growing populations was measured. The correlation analysis reveals a significant (p < 0.05) negative connection between 10-Octadecenoic acid methyl ester (FA1), and altitude. Edaphic factors like available nitrogen showed significantly (p < 0.05) but the negative correlation with cis-11-Eicosenoic acid, methyl ester (FA10; p < 0.001), Docosanoic acid, methyl ester (FA11; p < 0.05), Heptadecanoic acid, methyl ester (FA14; p < 0.05), and Tricosanoic acid, methyl ester (FA29; p < 0.05). Antioxidant activity did not show any variation in the seed oil of different populations but varied among the concentrations (5-50 µL) used. IC50 values of DPPH activity was significantly (p < 0.05) varied connect ranged from 11.31-24.21 µL/mL among the different populations. These variations in fatty acid composition and IC50 values of the DPPH activity can be one of the indicators for selecting a promising population that would be harnessed for its potential in nutraceuticals and cosmeceuticals industries.
