Diabetes is a metabolic disorder that causes higher levels of blood sugar due to insulin deficiency. Some of the natural products used for diabetes are CUR, capsicum oleoresin, quercetin, emodin, scutellarin, silybin, etc. CUR exhibits antitumour, anti-inflammatory, antioxidant and hypolipidemic properties. The poor water solubility of CUR is resolved by encapsulated CUR with nanoparticles. Capsicum oleoresin is an organic solvent that possesses antioxidant, anti-inflammatory and anticancer activities. Nanoemulsions of capsicum oleoresin decrease higher glucose levels. QC nanoparticles increase insulin secretion by reducing nitric oxide (NO) synthase activation. Nanoformulation of scutellarin promotes neovascularization by enhancing vascular permeability, which further improves diabetic retinopathy (16).

Cardamom (Elettaria cardamomum Maton) is a plant species native to Southeast Asia belonging to the family of Zingiberaceae.[1] Its dried fruit has a pleasant aroma, and it is used as a flavoring agent for food products[2] and also in the medicinal preparations. Cardamom essential oil (CEO) is the most important constituent of this plant that is obtained from dried fruit by steam distillation or solvent extraction. Essential oil or oleoresin contains the volatile essential oils of the plant as well as non-volatiles such as fixed oils, antioxidants such as phenolic compounds and pigments.[3] Essential oils are used in the food industry as flavorings agents. CEO is a colorless or very pale yellow liquid with an aromatic, penetrating odor and a strongly aromatic taste.[4] The major compounds of CEO are 1,8-cineole, α-terpineol, terpinyl acetate, d-limonene, sabinene and borneol.[5] CEO shows antimicrobial, antifungal, antioxidant, anti-inflammatory, antiseptic, carminative and diuretic activities.[3] CEO can be used as a functional food component representing higher health benefits compared to ordinary food products.

Pine oleoresin is an important forestry product. Oleoresin is a mixture of acidic and neutral diterpenes together with a variable fraction of volatile components (monoterpenes and sesquiterpenes, Langenheim 2003). Resin flows from existing (constitutive or primary resin) or traumatic (induced or secondary resin) resin canals (Barbosa and Wagner 1989). In the industry, the crude oleoresin is converted by steam distillation into gum turpentine (volatile compounds) and gum rosin (diterpenes), both gums, in turn, are processed into chemical industrial products such as food gums, adhesives, coatings, printing inks, disinfectants, cleaners, pharmaceuticals, fragrances, and flavoring (Rezzi et al. 2005).

Oleoresins are complex mixtures of acidic and neutral diterpenes together with a more or less important fraction of volatile compounds (monoterpenes and sesquiterpenes). Industrial processing by steam distillation converts the crude oleoresin into gum turpentine (volatile compounds) and gum rosin (diterpenes). Both gums in turn are further processed into chemical industrial products such as food gums, coatings, adhesives, cleaners, printing inks, disinfectants, pharmaceuticals, fragrances, and flavoring (Rezzi et al. 2005). Diterpene (C20) resin acids are the major components of rosin (da Silva Rodrigues-Correˆa, De Lima, and Fett-Neto 2013). Yadav, Yadav, and Goyal (2014) reported that diterpenoids and triterpenoids are not steam volatile, and they are obtained from plants, tree gums, and resins. Natural and synthetic resins (e.g. acrylic, phenolic, and formaldehyde) (Drobíková et al. 2015) have been used in several studies for the production of briquettes. Thoms, Snape, and Taylor (1999) studied the physical characteristics of cold cured anthracite/coke breeze briquettes prepared from a coal tar acid resin. Briquettes with excellent properties such as mechanical strength, thermal degradation, and water-proofing characteristics were produced. Benk (2010) studied briquette binders using air blown coal tar pitch and phenolic resins as raw materials. The optimum amount of air blown coal tar pitch was 50% w/w in the blended binder. The briquettes cured at 200°C for 2 h had a tensile strength of 50.45 MN/m2. When the cured briquettes were carbonized at temperatures of 470°C, 670°C, and 950°C, their strength increased with temperature up to 71.85 MN/m2. Sotannde, Oluyege, and Abah (2010) produced charcoal briquettes from neem wood residues using starch and gum arabic (gum extract from Acacia senegal L.) as binders. The briquettes were analyzed for fixed carbon, volatile matter, ash content, and heating value. The results showed that gum arabic bonded briquettes with a blending ratio of charcoal: binder of 10:3 had better physical and combustion qualities than starch bonded briquettes with a blending ratio of charcoal: binder of 5:1.
