Background:Benincasa hispida (BH) and Carissa congesta (CC) are regarded as ethnopharmacological imperative plants in Asian countries.Objective:Phytochemical screening of the extracts has shown the presence of steroids, flavonoids, saponins, glycosides, tannins, phenolic compounds, fixed oils, and fats in the BH and CC extracts. The presence of lupeol has been reported previously by us using high-performance thin-layer chromatography and high-performance liquid chromatography.Materials and Methods:Present research studies encompasses identification of chemical constituents in BH seeds and CC roots petroleum ether extracts by hyphenated technique such as gas chromatography-mass spectroscopy (MS) which when coupled gives a clear insight of constituents.Results:The components were identified by matching mass spectra with MS libraries. There were 13 and 10 different compounds analyzed from CC and BH, respectively. The components present were Pentanoic acid, 5-hydroxy, 2,4-butylphenyl; n-Hexadecanoic acid (Palmitic acid); Sulfurous acid, 2-ethylhexylhepatdecyl ester; n-Tridecane; 6-methyltridecane; (9E, 12E)-9,12-Octadecadienyl chloride, Hexadecanoic acid, 3-(trimethylsilyl)-oxy] propyl ester; 9,12-Octadecadenoic acid, 2 hydroxy-1-(hyroxymethylethyl) ester; 9,12-Octadecadienoic acid, 2,3 dihydroxypropyl ester; n-Propyl-9,12-Octadecadienoate, Lupeol; Taraxasterol; 6a, 14a-Methanopicene, perhydro-12,4a, 61a, 9,9,12a-hepatmethyl-10-hydoxy and 9-Octadecene; 2-Isoprpenyl-5-methyl-6-hepten-1-ol; n-Hexadecanoic acid, 2-hyroxy-1-(hydroxymethyl) ethyl ether; Butyl-9,12-Octadecadieonate; Friedoolean-8-en-3-one; friedours-7-en-3-one; 13,27-Cyclosuran-3-one; Stigmaste-7,25-dien-3-ol (3β, 5α); Stigmasta-7,16-dien-3-ol; chrondrillasterol in BH seeds and CC roots extracts respectively.Conclusion:Eluted components from the extracts could provide further researchers to work with various pharmacological activities related models and studies.

Ayurvedic therapeutics describes vast number of medicinal herbs used as “Vyadhirodhak Chamatav” that has enlightened the application of herbs used as corner stone in various diseases especially those modulating the immune system. Ayurveda literature comprises of rasayana and non-rasayana herbs. Materia Medica entirely enriched with enormous data of rasayana medicinal herbs acting as immunomodulators in existence. However, as such there is no specific review of literature available for non-Rasayana herbs that have immense potential as immunomodulators. This review article empowers data on non-rasayana medicinal herbs as promising future target for immunotherapy.

Objective:In Indian Ayurvedic system, Benincasa hispida (BH) and Carissa congesta (CC) are well-known plants used for major and minor ailments. BH has been regarded as Kushmanda, whereas CC has been used in immune-related disorders of the human system. Quercetin and rutin identified from the vast plethora of plant extracts have proved to possess ethnopharmacological relevance.Materials and Methods:In present studies, we have determined quercetin and rutin in terms of percentage in BH seeds and CC roots by high-performance thin layer chromatography (HPTLC) and high-performance liquid chromatography (HPLC). After extraction and phytochemical screening, the extracts were subjected to quantification for the presence of quercetin and rutin by HPTLC and HPLC.Results:HPTLC showed quercetin as 44.60, 27.13% and rutin as 32.00, 36.31% w/w, whereas HPLC revealed quercetin as 34.00, 35.00% and rutin as 21.99, 45.03% w/v in BH and CC extracts, respectively.Conclusion:The BH and CC extracts have elucidated peaks that were corresponding with standard peaks on undertaking chromatographic studies.SUMMARY Quercetin and rutin are isolated from BH seeds and CC roots by High Performance. Thin Layer Chromatography and High Performance Liquid Chromatography. HPTLC revealed presence of quercetin as 44.60, 27.13 % and rutin as 32.00, 36.31 % w/w. HPLC revealed presence of quercetin as 34.00, 35.00 % and rutin as 21.99, 45.03 % w/v. Abbreviation Used: HPTLC: High Performance Thin Layer Chromatography; HPLC: High Pressure Liquid Chromatography, UV: Ultraviolet, CC: Carissa congesta, BH: Benincasa hispida

Background:Carissa congesta (CC), Polyalthia longifolia (PL), and Benincasa hispida (BH) are economically important plants.Objective:Current research encompasses identification of quercetin and rutin and their analogues by liquid chromatography-mass spectroscopy (LC-MS) from the selected plant species.Materials and Methods:Fresh roots, leaves, and seeds of CC, PL, and BH plants respectively were shade-dried followed by extraction and elucidation of rutin and quercetin by LC-MS.Results:Structural elucidation of CC, PL, and BH extracts revealed the presence of flavonoids such as quercetin (m/z 301) and rutin (m/z 610) as the parent ions along with presence of close analogues such as quercetin-O-hexoside, Vicenin 2, quercetin-3-O-xyloside/arabinoside, and quercetin-3-O-glucoside were identified as fragments.Conclusions:Thus, CC, PL, and BH extracts revealed the presence of flavonoids belonging to the class of flavonols such as rutin and quercetin.SUMMARY Quercetin and rutin were identified from CC roots, PL leaves and BH seeds by liquid chromatography-mass spectroscopy.Quercetin was characterized at (m/z 301) and rutin (m/z 610) as the parent ion peaks.Analogues such as quercetin-O-hexoside, Vicenin 2 and quercetin-3-O-glucoside were identified as fragments.
