Taxiphyllin
|
Bamboo shoots contain high amounts of cyanogen glycoside, and the maximum concentration is at the shoot tip. |
Taxiphyllin is highly unstable and easily decomposed in boiling water. |

Glucosinolates
|
Levels of glucosinolates of all species vary slightly and range from 26.45 to 29.99 mg 100 g−1 f.w. |
Drying, fermentation, boiling, and soaking can significantly reduce the total glucosinolate content. |

Oxalates
|
Oxalate content depends on different species and ranges from 112.2 to 462.0 mg 100 g−1 f.w. |
All processing treatments cause a decrease in the oxalate content of fresh shoots, among which fermentation and freeze-drying are the best techniques for removing oxalates from bamboo shoots. |

Saponins
|
Ranging from 229.58 to 246.22 mg 100 g−1 f.w. |
Drying, fermentation, boiling, and soaking can significantly remove saponin. |

Phytate
|
Phytate content in the fresh shoots ranges from 86 (B. tulda) to 97 mg 100 g−1 f.w. (D. membranaceous). |
Fermentation, boiling, storage, and soaking can significantly remove phytate, but drying has no effect on phytate, and 100% reduction in phytate was obtained after six-month storage. |

Tannins
|
Tannins, being polyphenolic compounds, are heat labile and water soluble, and their content ranges from 31 to 51 mg 100 g−1 f.w. |
Boiling, fermentation, and soaking can effectively remove tannins but drying has no significant effect on tannins. |
