Organoleptic and physicochemical properties of natural-based herbal shampoo formulations with Cyclea peltata as a key ingredient.

BACKGROUND: Synthetic shampoos have toxic chemical agents like chemicals such as parabens and sodium lauryl sulfate which damage the hair. To combat this issue, the use of natural herbal shampoos, as opposed to synthetic shampoos, is becoming increasingly popular. One of the many medicinal plants present in Karnataka and Kerala is Cyclea peltata. This plant has long been known to assist in wound healing, allergy relief, and hair and scalp improvement, as well as serving as a coolant for hair applications. OBJECTIVE: The key subject of this research was the preparation of plant extracts and fermentation of Cyclea peltata leaf extract with Lactobacillus plantarum, resulting in the formulation of an herbal shampoo. METHOD: The leaf extract contained alkaloids, flavonoids, tannins, phenolic acid, saponins, and proteins, according to previous research by this group. The fermented product showed the presence of lactic acid, which was a boon for shampoo base as it protects the hair from the sunlight and improves the texture and strength of hair fibers. Cyclea peltata was used as the main ingredient in herbal shampoo formulations, along with other herbal ingredients, and the formulated shampoo was characterized for its different organoleptic (Color, odor) and physicochemical properties (pH, solid content, wettability, emulsification, and foam stability) to find the best formulation. RESULT: Formulation H2 showed better organoleptic and physicochemical properties and thus was chosen as the best formulation among the 11 formulations. CONCLUSION: Formulation H2 is regarded as the best formulation based on the results of the physicochemical tests (Pleasant odor, pH 3.01, solid content of 5.75%, wettability of 1.68 s, and percentage emulsification of 68.75%).

Tetrandrine isolated from Cyclea peltata induces cytotoxicity and apoptosis through ROS and caspase pathways in breast and pancreatic cancer cells.

Tetrandrine is a bisbenzylisoquinoline alkaloid known to exhibit anticancer activity against different cancers. In the present study, the cytotoxic effect of tetrandrine isolated from Cyclea peltata on pancreatic (PANC-1) and breast (MDA-MB-231) cancer cells was evaluated in vitro with an attempt to understand the role of tetrandrine on the generation of reactive oxygen species (ROS) and caspase activation. Results demonstrate the dose- and time-dependant cytotoxic effect of tetradrine on both MDA-MB-231 and PANC-1 cells with IC50 values ranging between 51 and 54 µM and 22 and 27 µM for 24 h and 48 h of incubation respectively. In addition, treatment of MDA-MB-231 and PANC-1 cells with tetrandrine showed the shrunken cytoplasm and damaged cell membrane in a dose- and time-dependant manner under the microscope. Also, tetrandrine treatment revealed an elevated levels of reactive oxygen species and increased activities of caspase-8, -9 and -3 confirming the apoptosis of cells through both extrinsic death receptor and intrinsic caspase activation. Therefore, the present study suggests the apoptosis of cells with the activation of caspase pathways mainly intrinsic pathway as a downstream event of tetrandrine-induced ROS generation. Hence, reactive oxygen species-mediated caspase activation pathway may be potentially targeted with the use of tetrandrine to treat breast and pancreatic cancers.

Optimization of column chromatography technique for the isolation of tetrandrine from Cyclea peltata and LC-ESI-MS based quantification and validation of the method.

Reverse phase column chromatography technique was employed to isolate tetrandrine from methanolic extract of Cyclea peltata roots. Tetrandrine was efficiently isolated using 0.02% aqueous diethylamine and methanol (25:75, v/v) as mobile phase with a purity of 98.63%. Compound characterisation was achieved using high-performance liquid chromatography coupled with electrospray ionization mass spectrometry and other spectroscopic methods. In addition, quantification of tetrandrine and validation of the method was carried out following International Conference on Harmonisation guidelines. The study provides a simple and cost effective method to isolate substantially good quantity and pure tetrandrine from Cyclea peltata.

Two azafluoranthene alkaloids and a phytoecdysone from the stems of Cyclea barbata.

Two new azafluoranthene alkaloids (1 and 2), and a new phytoecdysone (3), were isolated from the stems of Cyclea barbata Miers, together with six known compounds (4-9). Their structures were elucidated by spectroscopic data analysis and comparison with published data. This is the first report of azafluoranthene alkaloids (1 and 2) and phytoecdysones (3, 8, and 9) from Cyclea genus. In in vitro bioassay, four isolates (3, 5, 6, and 9) showed moderate hepatoprotective activity against N-acetyl-p-aminophenol (APAP)-induced toxicity in HepG2 cells.

Composition of phenolic compounds and antioxidant attributes of Cyclea gracillima Diels extracts.

Cyclea gracillima Diels is a Taiwanese native medicinal herb. However, there are currently few relevant reports on its biochemical activity. In this study, the antioxidant attributes of the ethanol and hot water extracts of this herb were assayed using in vitro models, including the following: 2,2-diphenyl-1-(2,4,6-trinitrophenyl)-hydrazyl radical scavenging, Trolox equivalent antioxidant capacity, reducing power, and chelating ferrous ions. The following biochemical models were also assayed: inhibition of human low density lipoprotein oxidation, inhibition of human erythrocyte hemolysis, and scavenging oxygen radicals in human blood. The composition and content of flavonoids and phenolic acids in these extracts were also analyzed. The results showed that these extracts with high polyphenol levels presented remarkable antioxidant effects in all assays, especially when extracted with ethanol. Six phenolic acids (mainly ferulic acid, sinapic acid, and syringic acid) and 12 flavonoids (mainly narigenin, myricetin, naringin, and apigenin) were found in these extracts.

Physicochemical properties of pectin from green jelly leaf (Cyclea barbata Miers).

The water extract of Green Jelly leaves (GJL) obtained by crushing the leaves in water (1:40) was capable of forming a gel at room temperature. The composition of GJL consisted mainly of carbohydrate (∼70w/w), protein (∼13% w/w) and minerals (∼6% w/w). The mineral portion consisted of mainly calcium (∼1.2% w/w), zinc (∼0.12% w/w) and magnesium (∼0.11% w/w). The isolated polysaccharide fraction (∼42.6% w/w) consisted of mainly galacturonic acid (∼35.8% w/w) and neutral sugars (∼6.8% w/w), with a weight-average molecular weight of ∼4.4×105g/mol. The results obtained by Fourier Transform Infra-Red (FTIR) showed that GJL polysaccharide fraction had a fairly similar FTIR fingerprint as the commercial low-methoxyl pectin (LMP). The degree of esterification of the polysaccharide changed drastically (from 97% to 10%) depending on the temperature used during the extraction process. The zeta potential of the extracted polysaccharide showed high negative charged as compared to the commercial LMP but close to sodium alginate. The study showed that the gelation was divalent cation-mediated and probably facilitated by the low degree of esterification which reduced steric hindrance from the methyl ester groups.

Bisbenzylisoquinoline alkaloids from the roots of cyclea tonkinensis.

Cissampentine A (1), an enantiomer of cissampentin, three new cycleatjehenine-type bisbenzylisoquinoline alkaloids, cissampentine B-D (2-4), and five known alkaloids were isolated from the roots of Cyclea tonkinensis. Their structures were established by interpretation of NMR, high-resolution ESI-MS data, and CD spectra. In vitro studies indicated that compounds 1 and 4 exhibited cytotoxicity against the HCT-8 tumor cell line (IC50 values of 8.97 and 9.73 µM, respectively), and compound 4 was also active against the Bel-7402 tumor cell line (IC50 value of 5.36 µM).

Effect of Cyclea peltata Lam. roots aqueous extract on glucose levels, lipid profile, insulin, TNF-alpha and skeletal muscle glycogen in type 2 diabetic rats.

In view of multi-dimensional activity of plant drugs beneficial to complex disorders like diabetes, the present study has been undertaken to evaluate the effect of aqueous extract of C. peltata roots on serum glucose, lipid profile, insulin, inflammatory marker namely tumour necrosis factor (TNF)-alpha and muscle glycogen in type 2 diabetic rats. Aqueous extract of C. peltata at 40 and 60 mg/kg dose significantly decreased both the fasting and postprandial blood glucose of type 2 diabetic rats; 60 mg/kg dose having more pronounced effect on hyperglycemia. An enhanced insulin levels by the aqueous extract is primary for its glucose and lipid lowering activity. The extract significantly decreased the elevated TNF-alpha in type 2 diabetic rats. The extract at 40 and 60 mg/kg dose increased the glycogen levels in skeletal muscle by 58 and 60% respectively. Improved glycogen in peripheral tissue such as skeletal muscle indicates the ability of plant drug to combat insulin resistance of type 2 diabetes.

Cytotoxic bisbenzylisoquinoline alkaloids from the roots of Cyclea racemosa.

Six new bisbenzylisoquinoline alkaloids, racemosidines A-C (1-3) and racemosinines A-C (4-6), and four known compounds were isolated from the roots of Cyclea racemosa. Compound 1 is the first bisbenzylisoquinoline alkaloid reported that has diphenyl ether bridges at C-11/C-7' and C-8/C-12' and a benzyl-phenyl ether bridge at C-7/C-11'. Structures and absolute configurations of 1-6 were established by interpretation of spectroscopic data and confirmed by X-ray crystallographic analysis of representative compounds. Compounds 1-3 exhibited significant cytotoxicity against HCT-8 and BEL-7402 tumor cells, and compound 1 was also cytotoxic against A2780 tumor cells.

Two new curine-type bisbenzylisoquinoline alkaloids from the roots of Cyclea wattii with cytotoxic activities.

Two new curine-type bisbenzylisoquinoline alkaloids, wattisines A (1) and B (2) along with three known alkaloids were isolated from the roots of Cyclea wattii. Their structures were established by interpretation of NMR and high-resolution electrospray ionization (ESI)-MS data. Absolute configuration of wattisines A and B were determined by single-crystal X-ray diffraction and circular dichroism (CD) spectra, respectively. In vitro, wattisine A (1) showed significant cytotoxic activities with IC(50) value of 1.74 microM against HCT-8, and 7.29 microM against Bel-7402.

Protective effect of Cyclea peltata Lam on cisplatin-induced nephrotoxicity and oxidative damage.

The aim of the present investigation was to evaluate the protective effect of a 70% methanolic leaf extract of Cyclea peltata Lam on cisplatin-induced renal toxicity. The concentration of creatinine, urea, sodium, and potassium in serum and levels of malonyldyaldehyde (MDA), glutathione (GSH), as well as gluathione peroxidase (GSH-Px), superoxide dismutase (SOD), and catalase (CAT) activities were determined in kidney tissue. The marked cisplatin-induced renal damage, characterized by a significant increase in creatinine and urea levels, decreased in extract-treated group, whereas sodium and potassium levels did not change significantly. C. peltata Lam extract significantly changed the increased MDA level and decreased GSH levels found in rats treated with cisplatin alone. The reduced activities of GSH-Px, SOD, and CAT in groups treated with cisplatin alone were significantly increased by the extract. The protective effect was greater in the post-treated than in the pre-treated group of animals. The results indicate that the post-treatment of C. peltata Lam extract might effectively ameliorate the oxidative stress parameters observed in cisplatin induced renal toxicity and could be used as a natural antioxidant against cisplatin-induced oxidative stress.

Modulatory effect of Cyclea peltata Lam. on stone formation induced by ethylene glycol treatment in rats.

The inhibitory effect of the root of Cyclea peltata Lam. on nephrolithiasis induced in rats by feeding with ethylene glycolated water (1%) for 35 days was summarized. Ethylene glycol administration led to oxalate stone formation, as indicated by its high level in urine. Complementary to this anion, the cation calcium level in urine was elevated. These two ions may have contributed to the formation of calcium oxalate stones. In addition to high serum potassium, a low serum magnesium level contributed to stone formation. Simultaneous administration of the powdered root of Cyclea peltata resulted in decreased urinary oxalate and calcium. Likewise, serum potassium was lowered and magnesium was elevated. These observations provided the basis for the conclusion that this plant inhibits the stone formation induced by ethylene glycol treatment.
