Background: The Cucurbitaceae family has been known for its presence of phytoconstituents, namely, lupeol, β-sitosterol, terpenoids, phenols, and proteins with therapeutic potential. Objectives: The research paper tries to focus on major therapeutic field of people demographic area of type of cancer. Soxhlet extraction of Benincasa hispida (BH) was carried out and crude extract was converted to powder. Niosomal gel was formulated after the optimization of drug concentration from the extract of Niosomal solution. Solution with maximum entrapment was selected for the preparation of gel. Gel was prepared by using different Carbopol grades and with comparison of different parameters. Gel was studied for gas chromatography-high-resolution mass spectrometry (GC-HRMS) evaluation for check toxicity. Biologic activity was analyzed by SRB (Sulforhodamine B) assay with in vitro cell lines (human oral cancer cell line KB and Mus Musculus skin melanoma B16-F10). Results: Solution which was clear and white was selected for gel development. Carbopol 934 (1{\textquoteright}) as gelling agent showed good formulation properties. It was non-gritty, easily spreadable, and washable. The gel with maximum entrapment efficiency was evaluated further. GC-HRMS revealed 1.2-ethyl 2-Hexen-1-ol; 1,8-(3-Octyl-2-oxiranyl)-1-octanol; Dodecanoic acid, 2-penten-1-yl ester; Cholestane, 4, 5-epoxy-,(4α,5α); Cyclopentaneundecanoic acid; 17-octadecynoic acid; Octadecanoic acid, methyl ester; Methyl oleate; Tridecanoic acid, methyl ester; and Silane, dimethyl (2,3,6, tricholrophenoxy) heptadicycloxy. The selected cell lines did not show satisfactory activity at different concentrations in SRB assay. Conclusion: This research paper tried to witness the probable potential of BH for cancer with analytical base. Future studies may be undertaken at various stages and levels to further explore the potential of these families of plants.

Background: Annonaceae and Apocynaceae families are known for their plethora of pharmacotherapeutic potential. Objectives: To evaluate antipsoriatic potential (ultraviolet [UV]-induced photodermatitis and tail model) and gas chromatography-mass spectrometry (GC-MS) studies on developed formulations from the plant extracts. Materials and Methods: Formulations of ethanolic extracts of Carissa congesta and Catharanthus roseus and petroleum ether extracts of Annona squamosa and Polyalthia longifolia were evaluated for antipsoriatic activity (UV-induced photodermatitis and tail model) at 250 and 500 mg/ kg. GC-MS studies were done subsequently after 6 months. Formulation batches were tested by different tests, viz., pH, viscosity, spreadability, washability, homogeneity, grittiness, drug content, Sudan red, bleeding, and sensitivity tests. Results: Histopathology studies indicated the absence of Munro{\textquoteright}s microabscess, regular elongation of rete ridges, capillary loop dilatation, granular cell layer, and prominent parakeratosis at 500 mg/kg. Formulations of the plant extracts did not reveal toxic components by GC-MS interpretation. No greasiness was observed during washing. Uniform homogeneity was observed with neither clumps nor large aggregates. The dispersed globules appeared red against colorless water background. Bleeding time was found to be stable during the experimentation. Conclusion: Developed topical plant formulations showed antipsoriatic potential on selected models. The GC-MS studies confirmed the presence of no drastic changes in the quantity of active constituents assuring its stability.

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.

Background: Polyalthia longifolia Thwaites is an important traditional plant in India. Rutin, an active constituent has been reported to possess good amount of pharmacological as well as therapeutic potential. Objective: The aim of the present study was to find out by analytical techniques how much percentage of rutin is present in the plant leaves{\textquoteright} ethanolic extract by analytical techniques. Materials and Methods: Shade dried leaves of Polyalthia longifolia were subjected to cold ethanolic extraction followed by monitoring the isolated rutin high-pressure liquid chromatography (HPLC) and high performance thin layer chromatography (HPTLC) after carrying out preliminary phytochemical screening. Results: Extraction yield was found to be 13.94\% w/w. Phytochemical screening of the extract showed the presence of flavonoids, steroids, diterpenoids, alkaloids, saponins, tannins and phenolic compounds and mucilage. From the Rf value, the ethanolic extract was found to be having constituent identical to rutin. By HPTLC and HPLC the amount of rutin was found to be 11.60\% w/w and 4.03\% w/v, respectively. Conclusion: The active constituent isolated was found to be equal to rutin.
