| "... sacred or Indian lotus, also known as the Rose of India and the sacred water lily of Hinduism and Buddhism. It is the national flower of India and Vietnam. Its roots and seeds are also used widely in Asian cooking... The flowers, seeds, young leaves, and "roots" (rhizomes) are all edible... The stamens can be dried and made into a fragrant herbal tea called liánhuā cha (蓮花茶) in Chinese, or (particularly in Vietnam) used to impart a scent to tea leaves. This Vietnamese lotus tea is called trà sen, chè sen, or chè ướp sen.

| | The comparative headspace analysis of living vs. picked N.nucifera flowers showed interesting variation of constituents (living/picked): sabinene (6.0/12.0%), 1,4-dimethoxybenzene (18.0/8.0%), terpinen-4-ol (3.0/1.5%), α-terpineol (9.0/1.0%), cis-jasmone (0.1%/not found). "...the character-donating component, para dimethoxy benzene, decreases markedly from 18% in the living lotus to 8% after picking..." \\ |

| "A solvent extract of Nelumbo nucifera ‘Shinnyoren’ flowers was investigated by GC and GC/MS. Seventy compounds were identified with the major constituents being hydrocarbons representing more than 75% of the extract. 1,4-Dimethoxybenzene, 1,8-cineole, terpinen-4-ol and linalool were found to be indispensible in characterizing the scent of lotus flower." \\ | "A solvent extract of Nelumbo nucifera ‘Shinnyoren’ flowers was investigated by GC and GC/MS.

| Main components of the scent (HS-GC/MS) were 1,4-dimethoxybenzene (45%), pentadecane (17%), sabinene (9.9%), hepta-x-ene (5%), 1,8-cineole (4.6%), and limonene (1.3%).

| "Different parts of N. nucifera, including the leaves, rhizomes, seeds and flowers, have been reported to have therapeutic potential in traditional medicine for the treatment of various diseases. Pharmacological activities of different extracts of rhizomes, seeds, leaves and flowers, and the compounds isolated from these extracts, have been demonstrated through numerous in-vitro and in-vivo test models. These include antioxidant, anti-inflammatory, antimicrobial, anti-arrhythmic, antipyretic, anti-ischaemic, anti-diabetic, hypoglycaemic, antidiarrhoeal, immunomodulatory and other activities. The responsible bioactive compounds belong to several chemical groups; mostly they are alkaloids (like dauricine, lotusine, nuciferine, liensinine, roemerine, neferine, armepavine), flavonoids (like kaempferol, quercetin, leucocyanidin, leucodelphinidin, catechin, isoquercitrin, astragalin), glycosides (nelumboroside A, nelumboroside B, isorhamnetin glycoside and isorhamnetin rutinoside), triterpenoid (like betulinic acid), vitamins and minerals. Thus, the pharmacological effects and various active ingredients of different parts of N. nucifera are well understood. This review highlights several pharmacological and phytochemical studies that have demonstrated the therapeutic potential of N. nucifera.
