Materials & Methods
Plant Material Collection & Extract Preparation: [38-44]
Flower petals of C. Ternatea were meticulously collected from diverse locations, including Sahibganj, home gardens, and nearby area. Subsequently, these petals were carefully dried for a period of 1-3 weeks before being transformed into a coarse powder using a mortar and pestle. To extract the plant's components, 100 grams of the resulting powder underwent a systematic, successive hot continuous soxhlet extraction with eleven solvents, each selected based on its polarity.
Prior to the extraction with each subsequent solvent, the powdered material was subjected to air-drying in a hot air oven maintained below 50°C. Following the effective extraction process, the solvents were distilled off, and the resulting extract was concentrated on a water bath. The weight of the extract obtained with each solvent was measured, and the percentage was calculated concerning the air-dried weight of the plant material.
To further analyze the different constituents, a TLC Plate Test Method (TLCPTM) [45-51] was employed, and the Retention Factor (R.F) was calculated to discern the various components present in the extracts. This comprehensive methodology provides a detailed insight into the chemical composition of C. Ternatea flower petals collected from distinct geographical locations.

Further analysis of the flower's composition revealed the presence of flavonol glycosides, specifically 3-O-(2"-O-alpharhamnosyl-6"-O-malonyl)-beta-glucoside of kaempferol, quercetin, and myricetin. Delphinidin glycosides, including 3-O-beta-glucoside, 3-O-(2"-O-alpha-rhamnosyl)-beta-glucoside, and 3-O-(2"-O-alpha-rhamnosyl-6"-O-malonyl)-beta-glucoside of delphinidin, were also identified. Furthermore, eight anthocyanins were isolated from the flowers, including ternatins C1, C2, C3, C4, C5, and D3, as well as preternatins A3 and C4 [55-58] (Figure 3).
Flavonoids: To test for the presence of flavonoids, 0.5 ml of alcohol extracts of the C. Ternatea extract were introduced into a test tube. Subsequently, 5-10 drops of diluted hydrochloric acid (HCl) were added, along with a small piece of magnesium. The solution was then boiled for a few minutes. The presence of flavonoids, the solution exhibited a distinctive pink, reddish-pink, or brown coloration. This color change served as an indicator of the presence of flavonoid compounds in the tested sample.
Alkaloids: The Wagner's Test for alkaloids was conducted by acidifying 1 ml of the alcoholic extract of the C. Ternatea extract with 1.5% hydrochloric acid (HCl) and introducing a few drops of Wagner's reagent. The formation of a brown precipitate indicated a positive test for alkaloids. This distinctive color change served as confirmation for the presence of alkaloid compounds in the tested sample.
Glycosides: The detection of glycosides involved dissolving a small amount of alcohol extracts from the C. Ternatea extract in a mixture of 1 ml water and 1N sodium hydroxide (NaOH) solution. The emergence of a yellow color during this process was indicative of the presence of glycosides in the tested sample. This distinct color change served as a positive indication for the presence of glycoside compounds in the tested sample.
Steroids: The Liberman-Burchard’s Test for steroids was conducted by combining the ethanolic extract of the C. Ternatea extract with chloroform (CHCl3) and acetic anhydride. Following this, 1 ml of concentrated sulfuric acid was introduced. The presence of steroids was affirmed by the development of a reddish-brown ring at the interface of the two layers. This distinctive color change acted as a positive indication for the presence of steroid compounds in the tested sample.
Phenols: For the detection of phenols, a small quantity of alcohol extracted from the C. Ternatea extract was dissolved in 2 ml of distilled water, and a few drops of 10% ferric chloride solution were added. The presence of phenols was indicated by the production of a blue or green color. This color change served as confirmation for the presence of phenolic compounds in the tested sample.
Saponins: For the detection of saponins, a small quantity of alcohol extract from the C. Ternatea extract was dissolved in 5 ml of distilled water. The mixture was shaken vigorously and left undisturbed for 3 minutes. The presence of saponins was indicated by the formation of a honeycomb-like froth. This distinctive froth served as confirmation for the presence of saponin compounds in the tested sample.
Tannins: To detect the presence of tannins, a few drops of 5% aqueous ferric chloride solution were added to the ethanolic extract of the C. Ternatea extract. The development of a bluish-black color indicated the presence of tannins in the tested sample.
