Ocimum tenuiflorum L. (syn. Ocimum sanctum L.) · Family: Lamiaceae · Leaf Extract
An adaptogenic Tulsi (Holy Basil) leaf extract standardised to ursolic acid NLT 2.5% by HPLC. Prepared from the leaf of Ocimum tenuiflorum for immunity, respiratory-wellness, adaptogenic, functional-food and beverage formulators. CoA-backed, HPLC-authenticated supply from India.
Standardised Grade
Ocimum tenuiflorum · 2.5% Ursolic AcidA standardised adaptogen active from Ayurveda's "Queen of Herbs"
Tulsi (Ocimum tenuiflorum L.), or Holy Basil, is among the most revered plants in Ayurveda, where it is known as the "Queen of Herbs" and used as a classical rasayana and adaptogen for immunity, respiratory wellness and stress balance. The leaf is rich in triterpenoid acids, rosmarinic acid and an aromatic essential oil, and concentrated, standardised extracts let formulators deliver those actives at a controlled, verifiable specification.
The characteristic constituents of Tulsi are its triterpenoid acids — notably ursolic acid and oleanolic acid — together with rosmarinic acid, eugenol, ocimumosides and a broad flavonoid and polyphenol complex. SV Botanica standardises this extract to ursolic acid of not less than 2.5% by HPLC, so every batch is defined by its most meaningful marker rather than by colour alone. Polyphenol-rich and full-spectrum (native-ratio) grades are also available.
The extract is finished as a free-flowing powder, brown to greenish-brown in colour, with a cold-water-soluble grade offered for beverages and teas. That flexibility makes it well suited to capsules, tablets and herbal blends as well as aqueous functional beverages and wellness shots. Slight colour and aroma variation between batches is normal for a herbal material and reflects natural variation in the raw leaf.
We supply supplement brands, functional-food and beverage manufacturers and Ayurvedic formulators against buyer specifications, with a batch-specific Certificate of Analysis on every shipment.
The triterpenoids and polyphenols that define Holy Basil leaf
The pentacyclic triterpenoid that defines the extract. Standardised here to NLT 2.5% by HPLC — the primary assay basis of every batch.
A triterpenoid isomer of ursolic acid that co-occurs in Holy Basil leaf and contributes to its characteristic marker profile.
A principal phenolic acid of the Lamiaceae family, widely used to characterise the antioxidant profile of Tulsi leaf.
The main phenylpropanoid of Holy Basil's aromatic essential oil and a key point of botanical identity.
Characteristic glycosides of Ocimum studied for the plant's traditional adaptogenic, stress-balancing role.
Apigenin, orientin and the broader phenolic complex underpin the leaf's recognised antioxidant activity.
Why formulators specify a standardised Tulsi extract — the functional role of the markers
Ursolic acid, the characteristic triterpenoid of Holy Basil leaf, is widely studied for antioxidant and metabolic activity. A defined ursolic-acid percentage lets formulators build adaptogen and daily-wellness products on a consistent, verifiable active load.
Standardisation to ursolic acid by HPLC, with identity confirmed by TLC, gives a defensible identity and assay for a leaf extract that is otherwise easy to under-declare or dilute.
A cold-water-soluble grade suits aqueous beverages, wellness shots and teas, while the standard ursolic-acid grade is partially water-soluble and ideal for capsules, tablets and herbal blends.
Tulsi is one of Ayurveda's most recognised herbs for immunity and respiratory wellness, giving brands a familiar, label-friendly hero ingredient for seasonal-support and daily-wellness lines.
As Ayurveda's premier rasayana and “the Incomparable One”, Holy Basil is a recognised adaptogenic active for stress-balance, calm-energy and modern nootropic formats.
A free-flowing powder passing ≥95% through a 40-mesh sieve with controlled bulk density disperses and blends predictably across batches.
These are functional and physico-chemical properties of the actives; SV Botanica does not make medical or therapeutic claims for this ingredient.

The 2.5% ursolic acid grade is our CoA-backed flagship, standardised by HPLC with identity confirmed by TLC. Alternative standardisations, native-ratio (full-spectrum) and cold-water-soluble extracts, custom mesh and packaging can be quoted against buyer specification and order volume. Every batch is released against a batch-specific Certificate of Analysis.
Tulsi Extract is bought in five forms. The standardised extract is the stocked item; granulated and dispersible grades are produced on request and raw botanical forms are sourced against a confirmed order.
| Form | What it is | Specification basis | Availability |
|---|---|---|---|
| Standardised extract powder | Ocimum tenuiflorum leaf extract, dried and milled | NLT 2.5% ursolic acid (HPLC) | Stocked |
| Granulated (direct-compression) | Extract granulated for tablet lines | Same marker, declared on the granule | On request |
| Water-dispersible / soluble | Extract in a dispersible matrix for beverages, gummies and sachets | Marker declared on the matrix basis; carrier named | On request |
| Leaf powder (non-extracted) | Dried Ocimum tenuiflorum leaf, milled to mesh | Botanical identity by TLC; heavy metals and microbial panel | On enquiry, subject to lot; phytosanitary certificate usually required |
| Cut leaf (tea-bag cut) | Dried leaf, tea-bag cut or cut & sifted | Identity, moisture, foreign matter | On enquiry; for teas and in-house extraction |
A marker percentage without its assay method is not a specification; ask for the method and the plant part on every quotation.

*The product is of herbal origin; slight colour variation may occur due to geographical and seasonal variation in the raw material. Ursolic acid is standardised by HPLC and identity is confirmed by TLC. A current Certificate of Analysis and MSDS are issued with every batch. EU pesticide MRL reports are available on request.
From leaf to standardised extract — authenticated, tested, documented
Raw Material & Authentication: The extract is prepared from cultivated Ocimum tenuiflorum leaf. Because leaf extracts can be diluted or under-declared, ursolic-acid identity is confirmed by TLC and ursolic-acid content is assayed by HPLC on every batch before it is accepted.
Manufacturing & Testing: Tulsi Dry Extract is manufactured at certified facilities in India. Each batch runs through a full QC battery — ursolic acid assay by HPLC, loss on drying, pH, bulk density, ash and mesh, heavy metals by ICP-MS, pesticide residue screening, and a complete USP microbiological panel — before release.
Documentation: Every shipment is supplied against a batch-specific Certificate of Analysis with an MSDS. Halal, Kosher and Organic certification are available. Country of Origin and export documentation are provided on request. For buyers shipping into the EU, see our guides on EU pesticide MRL compliance and EU import requirements for botanical extracts.
