Passion Flower Extract

Thovek supplies Passiflora incarnata dry extract produced from the dried aerial parts — leaf, stem, tendril and flower harvested at flowering — and not from the flower alone, since the aerial part (herba) is the plant part recognised in the European pharmacopoeial monograph for this material. The characteristic constituents are C-glycosyl flavones: vitexin (apigenin-8-C-glucoside) and its 6-C isomer isovitexin, alongside orientin, isoorientin, schaftoside and isoschaftoside. Our standard commercial grade assays 4.0% total flavones calculated as vitexin by HPLC. A 1.5–2.0% total-flavonoid grade determined spectrophotometrically and expressed as vitexin is available for buyers working to the pharmacopoeial figure for the herb and its ethanolic extracts, and plain 10:1 and 20:1 native extracts are made for formulators who specify by ratio rather than by marker. Species identity is the real quality risk in this trade. Passiflora edulis and several other Passiflora species are cheaper, visually similar once dried and cut, and do not carry the same flavone profile, so every incoming lot of raw herb is confirmed by HPTLC and HPLC fingerprint against a P. incarnata reference before it enters the extractor. Extraction uses water or food-grade ethanol/water; no class 1 solvents are involved and residual solvents are held within ICH Q3C class 3 limits. Assay is adjusted with maize or tapioca maltodextrin where a fixed percentage is contracted, and a carrier-free native extract can be supplied where the buyer prefers to dilute in-house. The trace beta-carboline alkaloids native to the herb (harman, harmine, harmaline) are monitored and reported on request, because a few destination markets ask for a declared ceiling on them. The powder is free-flowing at 80 mesh and blends without segregation into two-piece capsules, direct-compression tablet blends, instant sachets and effervescent sticks; the maltodextrin-carried grade disperses in cold water for beverage and gummy work. The material is wholly plant-derived — vegan and vegetarian, with no milk, egg, soy, fish, crustacean, tree nut, peanut, sesame or gluten-containing input at any stage — and it is non-GMO and not irradiated. Brands typically position passion flower in the evening and relaxation category; Thovek makes no representation as to physiological effect and sells the material on its analytical specification alone. Documentation travels with the goods: full COA with HPLC chromatogram, MSDS, allergen and GMO statements, BSE/TSE-free declaration, manufacturing flow chart, and organic certification under NPOP, NOP or EU rules where contracted.
